Shih Tzus do not age at the same speed as humans, and they also age differently from larger dog breeds.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The old idea that <strong>one dog year equals seven human years<\/strong> is too simple. Shih Tzus grow quickly during puppyhood, reach maturity early, and then age more slowly through adulthood because they are a small companion breed.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide helps you understand <strong>Shih Tzu age in human years<\/strong> using a small-breed age pattern. It is designed to help you quickly compare dog years, human years, and life stages without treating every dog breed the same.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This Shih Tzu age chart reflects:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Fast development during the first year<\/li>\n\n\n\n<li>Continued maturity during the second year<\/li>\n\n\n\n<li>Slower, steadier aging through adult years<\/li>\n\n\n\n<li>Senior life stages that usually begin around age 10<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a <strong>1-year-old Shih Tzu is about 15 human years old<\/strong>, while a <strong>5-year-old Shih Tzu is about 36 human years old<\/strong>. A <strong>10-year-old Shih Tzu is roughly 56 human years old<\/strong> and is usually considered a senior dog.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This chart is useful for a quick estimate. For an exact input-based result, you can use our <a href=\"https:\/\/petageinhumanyearscalculator.com\/dog-age-calculator\/shih-tzu-dog-age-calculator\/\">Shih Tzu dog age calculator<\/a> after checking the age chart.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Knowing your Shih Tzu\u2019s human-equivalent age can help you understand:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Age-appropriate behavior and energy levels<\/li>\n\n\n\n<li>When your Shih Tzu becomes an adult or senior<\/li>\n\n\n\n<li>How to adjust food, exercise, and daily care by age<\/li>\n\n\n\n<li>When to plan routine vet checkups and senior health monitoring<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">Shih Tzu Age Chart: Dog Years to Human Years Conversion<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The chart below shows the estimated conversion from <strong>Shih Tzu dog years to human years<\/strong>. This is the fastest way to check your dog\u2019s approximate human age and life stage.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Because Shih Tzus are small dogs, they usually age more slowly than large dogs after the first few years. That is why a Shih Tzu age chart is more useful than a general dog age chart.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Shih Tzu Dog Age to Human Age Chart<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Shih Tzu Age<\/th><th>Human Age Equivalent<\/th><th>Life Stage<\/th><\/tr><\/thead><tbody><tr><td>1 year<\/td><td>15 years<\/td><td>Puppy \/ young adolescent<\/td><\/tr><tr><td>2 years<\/td><td>24 years<\/td><td>Young adult<\/td><\/tr><tr><td>3 years<\/td><td>28 years<\/td><td>Adult<\/td><\/tr><tr><td>4 years<\/td><td>32 years<\/td><td>Adult<\/td><\/tr><tr><td>5 years<\/td><td>36 years<\/td><td>Adult<\/td><\/tr><tr><td>6 years<\/td><td>40 years<\/td><td>Adult<\/td><\/tr><tr><td>7 years<\/td><td>44 years<\/td><td>Adult<\/td><\/tr><tr><td>8 years<\/td><td>48 years<\/td><td>Mature adult<\/td><\/tr><tr><td>9 years<\/td><td>52 years<\/td><td>Mature adult<\/td><\/tr><tr><td>10 years<\/td><td>56 years<\/td><td>Senior<\/td><\/tr><tr><td>11 years<\/td><td>60 years<\/td><td>Senior<\/td><\/tr><tr><td>12 years<\/td><td>64 years<\/td><td>Senior<\/td><\/tr><tr><td>13 years<\/td><td>68 years<\/td><td>Senior<\/td><\/tr><tr><td>14 years<\/td><td>72 years<\/td><td>Senior<\/td><\/tr><tr><td>15 years<\/td><td>76 years<\/td><td>Senior<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<p class=\"wp-block-paragraph\">This chart gives an estimate, not an exact medical age.

A <strong>12-year-old Shih Tzu is about 64 human years old<\/strong>, while a <strong>15-year-old Shih Tzu is roughly 76 human years old<\/strong>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For a deeper breakdown of lifespan, breed traits, and care needs, see our complete <a href=\"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-dog\/\">Shih Tzu dog guide<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Shih Tzu Dog Years Are Not Equal to 7 Human Years<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">You may have heard that <strong>one dog year equals seven human years<\/strong>. This rule is common, but it is not accurate for Shih Tzus.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dogs do not age in a straight line. They grow very fast at the start of life, then their aging slows down later. A Shih Tzu can reach adult size in about the first year, while humans take many years to reach the same stage of development.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 7-year rule does not work well because:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Shih Tzus mature quickly in the first year<\/li>\n\n\n\n<li>The second year still adds a large amount of human-equivalent age<\/li>\n\n\n\n<li>Adult aging slows down after age 2<\/li>\n\n\n\n<li>Small dogs like Shih Tzus often live longer than large dogs<\/li>\n\n\n\n<li>One fixed formula cannot match every breed and size<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For example, a <strong>1-year-old Shih Tzu is closer to a teenager than a 7-year-old child<\/strong>. A <strong>10-year-old Shih Tzu is not exactly 70 in human years<\/strong>; using a small-breed chart, they are closer to about 56 human years.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">That is why this page uses a small-breed aging pattern instead of the old 7-year rule. It gives a more useful estimate for understanding your Shih Tzu\u2019s life stage.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Shih Tzu Life Stages Explained: Puppy, Adult, and Senior Years<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding your Shih Tzu\u2019s life stage is just as important as knowing the number in human years. Life stage helps explain changes in behavior, energy, sleep, exercise needs, and health care.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most Shih Tzus move through three main life stages: <strong>puppy, adult, and senior<\/strong>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Shih Tzu life stages by age<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Shih Tzu Age<\/th><th>Life Stage<\/th><th>What This Means<\/th><\/tr><\/thead><tbody><tr><td>0\u20131 year<\/td><td>Puppy<\/td><td>Fast growth, training, social learning, high energy<\/td><\/tr><tr><td>1\u20139 years<\/td><td>Adult<\/td><td>Stable energy, full size, active daily routine<\/td><\/tr><tr><td>10+ years<\/td><td>Senior<\/td><td>Slower movement, more rest, possible age-related changes<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Puppy stage: 0\u20131 year<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Shih Tzu puppies grow quickly during the first year. This is the stage when they learn basic training, build social confidence, explore their environment, and develop daily routines.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>They need gentle training and socialization<\/li>\n\n\n\n<li>They usually have short bursts of playful energy<\/li>\n\n\n\n<li>They need age-appropriate meals and vet visits<\/li>\n\n\n\n<li>They may reach adult size by around the end of the first year<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Adult stage: 1\u20139 years<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The adult stage is usually the longest part of a Shih Tzu\u2019s life. During this stage, most Shih Tzus have more predictable behavior, steady energy, and a more settled daily routine.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Energy levels are usually steady<\/li>\n\n\n\n<li>Behavior becomes calmer and more predictable<\/li>\n\n\n\n<li>Weight control becomes important<\/li>\n\n\n\n<li>Regular grooming, dental care, and checkups help support long-term health<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For help with behavior routines during this stage, see the <a href=\"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-training-guide\/\">Shih Tzu training guide<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Senior stage: 10 years and older<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A Shih Tzu is usually considered a <strong>senior dog around age 10<\/strong>. This does not mean your dog is suddenly unhealthy, but it does mean their care needs may start to change.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>They may sleep more than before<\/li>\n\n\n\n<li>Walks may need to become shorter or slower<\/li>\n\n\n\n<li>Vision, hearing, teeth, joints, or memory may change with age<\/li>\n\n\n\n<li>Vet checkups may become more important for early problem detection<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Not all senior Shih Tzus age the same way. Some 12-year-old Shih Tzus remain playful and alert, while others need extra comfort and support earlier. For senior care routines, food guidance, and daily care planning, visit the <a href=\"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-dog-nutrition-feeding-guide\/\">Shih Tzu nutrition and feeding guide<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How Your Shih Tzu\u2019s Age Affects Daily Care<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Once you know your Shih Tzu\u2019s age in human years, it becomes easier to understand what kind of care they may need. A puppy, adult, and senior Shih Tzu can all have very different energy levels, food needs, exercise limits, and health risks.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The age chart gives you an estimate of your dog\u2019s life stage. Daily care should still be based on your Shih Tzu\u2019s actual health, weight, activity level, and advice from your vet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Care tips by Shih Tzu life stage<\/h3>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Life Stage<\/th><th>Main Care Focus<\/th><th>What to Watch For<\/th><\/tr><\/thead><tbody><tr><td>Puppy<\/td><td>Growth, training, vaccines, socialization<\/td><td>Fast growth, chewing, house training, short attention span<\/td><\/tr><tr><td>Adult<\/td><td>Weight control, exercise, grooming, routine checkups<\/td><td>Weight gain, dental buildup, low activity, skin or coat issues<\/td><\/tr><tr><td>Senior<\/td><td>Comfort, joint support, dental care, regular vet checks<\/td><td>Slower movement, more sleep, vision, hearing, or behavior changes<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Food and weight control by age<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Keeping your Shih Tzu at a healthy weight is one of the most important parts of age-based care. Extra weight can make senior years harder because it may add pressure on the joints, breathing, and heart.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Puppies need food that supports healthy growth<\/li>\n\n\n\n<li>Adult Shih Tzus need portion control to avoid weight gain<\/li>\n\n\n\n<li>Senior Shih Tzus may need diet changes based on vet advice<\/li>\n\n\n\n<li>Treats should stay limited, especially for less active dogs<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">For a deeper feeding breakdown, use the <a href=\"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-dog-nutrition-feeding-guide\/\">Shih Tzu nutrition and feeding guide<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Exercise and mental activity by age<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Shih Tzus do not usually need heavy exercise, but they still need daily movement and mental activity. The right routine depends on their age and comfort level.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Puppies often do best with short play sessions and rest breaks<\/li>\n\n\n\n<li>Adults usually enjoy short walks and gentle daily play<\/li>\n\n\n\n<li>Senior Shih Tzus may need slower walks and softer activities<\/li>\n\n\n\n<li>Simple games can help keep your dog mentally active at any age<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">As your Shih Tzu gets older, you usually do not need to remove activity completely. Instead, slow down the pace, shorten the session, and watch for signs of tiredness or discomfort.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Vet care and senior health checks<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Regular vet care helps catch age-related problems early. This becomes more important when your Shih Tzu reaches senior age, which is usually around 10 years old.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Puppies need regular visits for vaccines and early growth checks<\/li>\n\n\n\n<li>Adult Shih Tzus usually need routine yearly checkups<\/li>\n\n\n\n<li>Senior Shih Tzus may benefit from more frequent vet visits<\/li>\n\n\n\n<li>Dental checks are important because small dogs can develop dental issues with age<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Older Shih Tzus may need closer monitoring for teeth and gums, joints and movement, eyes and hearing, weight changes, and behavior changes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Extra care for senior Shih Tzus<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Senior Shih Tzus may need small changes at home to stay comfortable. These changes are especially helpful if your dog moves more slowly, sleeps more, or avoids jumping like they used to.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use a soft, supportive bed<\/li>\n\n\n\n<li>Keep food and water easy to reach<\/li>\n\n\n\n<li>Add ramps or steps if your dog struggles with furniture<\/li>\n\n\n\n<li>Keep grooming gentle and consistent<\/li>\n\n\n\n<li>Watch for sudden changes in appetite, movement, sleep, or behavior<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\">Regular coat and skin care also becomes more important with age. For simple grooming routines, see the <a href=\"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-grooming\/\">Shih Tzu grooming guide<\/a>.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you notice pain, confusion, major behavior changes, sudden weight loss, or difficulty walking, talk to your vet. These signs should not be ignored as \u201cjust old age.\u201d<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">To calculate your dog\u2019s exact age faster, use the <a href=\"https:\/\/petageinhumanyearscalculator.com\/dog-age-calculator\/shih-tzu-dog-age-calculator\/\">Shih Tzu dog age calculator<\/a> after checking the chart.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Frequently Asked Questions<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">How old is a Shih Tzu in human years?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A Shih Tzu\u2019s age in human years depends on their life stage. A 1-year-old Shih Tzu is about 15 human years old, a 2-year-old Shih Tzu is about 24 human years old, and after age 2 most Shih Tzus age by about 4 human years for each dog year.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How old is my Shih Tzu in human years?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">You can estimate your Shih Tzu\u2019s human age by using the age chart above. Find your dog\u2019s age in the first column, then compare it with the human age equivalent. For a faster input-based result, use the <a href=\"https:\/\/petageinhumanyearscalculator.com\/dog-age-calculator\/shih-tzu-dog-age-calculator\/\">Shih Tzu dog age calculator<\/a>.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How old is a 5-year-old Shih Tzu in human years?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 5-year-old Shih Tzu is about 36 years old in human years. At this age, most Shih Tzus are still adults and may have steady energy with proper food, exercise, and care.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is 7 years old for a Shih Tzu?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 7-year-old Shih Tzu is not usually considered very old. In human years, a 7-year-old Shih Tzu is about 44 years old. This is usually still an adult stage, although some dogs may start showing early signs of slowing down.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How old is a 10-year-old Shih Tzu in human years?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 10-year-old Shih Tzu is about 56 years old in human years. This is usually the age when many Shih Tzus begin entering the senior life stage.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is 10 years old for a Shih Tzu?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, 10 years old is usually considered senior age for a Shih Tzu. Many Shih Tzus can still be active at this age, but they may need more careful monitoring, gentler exercise, and regular vet checkups.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How old is a 12-year-old Shih Tzu in human years?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 12-year-old Shih Tzu is about 64 years old in human years. At this age, your dog may need more comfort, dental care, joint support, and closer health monitoring.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How old is a 14-year-old Shih Tzu in human years?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A 14-year-old Shih Tzu is about 72 years old in human years. This is a senior age, so comfort, gentle movement, routine vet care, and a stable daily routine become more important.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">When is a Shih Tzu considered a senior?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Most Shih Tzus are considered senior dogs around age 10. Some may slow down earlier or later depending on genetics, weight, activity level, and overall health.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">At what age do Shih Tzus slow down?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Many Shih Tzus start slowing down between 8 and 10 years old, but this varies by dog. Some remain playful into their senior years, while others may need gentler routines earlier.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Why is the 7-year rule wrong for Shih Tzus?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The 7-year rule is inaccurate because dogs age quickly in the first two years and then slow down. Small breeds like Shih Tzus usually live longer than large dogs, so one fixed rule does not match their aging pattern well.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Do Shih Tzus age slower than other dogs?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Shih Tzus usually age slower than large dog breeds after the first couple of years. Like many small dogs, they often have a longer lifespan and may stay active later into life with proper care.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Final thoughts<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A Shih Tzu age chart helps you quickly understand your dog\u2019s age in human years, but it should be treated as an estimate. Your dog\u2019s real health and life stage also depend on weight, genetics, diet, activity level, dental care, and regular vet support.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Use this Shih Tzu age chart as a simple guide, then check your dog\u2019s exact input-based result with the <a href=\"https:\/\/petageinhumanyearscalculator.com\/dog-age-calculator\/shih-tzu-dog-age-calculator\/\">Shih Tzu dog age calculator<\/a> if you want a faster conversion.<\/p>\n\n\n\n<script type=\"application\/ld+json\">\n{\n  \"@context\": \"https:\/\/schema.org\",\n  \"@graph\": [\n    {\n      \"@type\": \"WebSite\",\n      \"@id\": \"https:\/\/petageinhumanyearscalculator.com\/#website\",\n      \"url\": \"https:\/\/petageinhumanyearscalculator.com\/\",\n      \"name\": \"Pet Age in Human Years Calculator\",\n      \"inLanguage\": \"en\"\n    },\n    {\n      \"@type\": \"WebPage\",\n      \"@id\": \"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-age-calculator-human-years\/#webpage\",\n      \"url\": \"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-age-calculator-human-years\/\",\n      \"name\": \"Shih Tzu Dog Age Calculator to Human Years (With Age Chart)\",\n      \"isPartOf\": {\n        \"@id\": \"https:\/\/petageinhumanyearscalculator.com\/#website\"\n      },\n      \"primaryImageOfPage\": null,\n      \"inLanguage\": \"en\",\n      \"breadcrumb\": {\n        \"@id\": \"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-age-calculator-human-years\/#breadcrumb\"\n      },\n      \"mainEntity\": {\n        \"@id\": \"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-age-calculator-human-years\/#blogposting\"\n      }\n    },\n    {\n      \"@type\": \"BreadcrumbList\",\n      \"@id\": \"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-age-calculator-human-years\/#breadcrumb\",\n      \"itemListElement\": [\n        {\n          \"@type\": \"ListItem\",\n          \"position\": 1,\n          \"name\": \"Home\",\n          \"item\": \"https:\/\/petageinhumanyearscalculator.com\/\"\n        },\n        {\n          \"@type\": \"ListItem\",\n          \"position\": 2,\n          \"name\": \"Blog\",\n          \"item\": \"https:\/\/petageinhumanyearscalculator.com\/blog\/\"\n        },\n        {\n          \"@type\": \"ListItem\",\n          \"position\": 3,\n          \"name\": \"Shih Tzu Dog Age Calculator to Human Years (With Age Chart)\",\n          \"item\": \"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-age-calculator-human-years\/\"\n        }\n      ]\n    },\n    {\n      \"@type\": \"Person\",\n      \"@id\": \"https:\/\/petageinhumanyearscalculator.com\/#author\",\n      \"name\": \"Site Author\"\n    },\n    {\n      \"@type\": \"BlogPosting\",\n      \"@id\": \"https:\/\/petageinhumanyearscalculator.com\/blog\/shih-tzu-age-calculator-human-years\/#blogposting\",\n      \"headline\": \"Shih Tzu Dog Age Calculator to Human Years (With Age Chart)\",\n      \"description\": \"See how old your Shih Tzu is in human years.
