Shih Tzus have a way of staying puppy-like forever, but just like us, they do get older. And if you’ve had your furry best friend by your side for several years, you may start to notice a few changes. Aging is natural, but knowing what to expect can help you support your pup through their golden years with a little extra care and a lot of love.

Slowing Down a Bit

You might notice your Shih Tzu isn’t as quick to jump up on the couch or doesn’t want to play as long as they used to. Maybe those daily walks are getting a little shorter. This doesn’t mean they’re unwell, it just means their joints and muscles aren’t what they once were. A slower pace is one of the most common signs of aging.

Graying Around the Face

Just like people, dogs can get gray hair as they age. You may see some white or gray popping up around their muzzle, eyes, or ears. It’s totally normal and doesn’t affect their health, it’s just one of those sweet little signs they’ve been with you a long time.

Cloudy Eyes or Changes in Vision

Aging can affect your Shih Tzu’s eyesight. If their eyes start to look a little cloudy, it could be due to a condition called nuclear sclerosis, which is common in older dogs. It’s not painful, but it can affect their vision a bit. If you’re ever unsure, it’s always a good idea to have your vet take a look.

More Naps, Fewer Zoomies

Older Shih Tzus love their naps, and they’ve earned them! If your pup is sleeping more than usual, that’s a sign their energy levels are naturally decreasing with age. Make sure they have a comfy, quiet spot to rest, especially if your house is busy.

Weight Gain or Loss

Changes in metabolism can affect your Shih Tzu’s weight as they age. Some may gain a little, while others lose weight without a major change in diet. Either way, it’s worth mentioning to your vet to make sure everything is on track.

Dental Trouble and Bad Breath

Dental health becomes more important as dogs age. If your Shih Tzu has bad breath, trouble chewing, or starts avoiding their food, their teeth or gums could be bothering them. Regular brushing and plaque control products like the ones we love from PawTree can help keep those pearly whites in better shape.

Hearing Loss

If your Shih Tzu isn’t responding to their name or usual commands, it might not be stubbornness; it could be hearing loss. Try using hand signals or tapping the floor gently to get their attention if needed.

Behavioral Changes

Some senior dogs can become more anxious, clingy, or even more independent than usual. You might also notice potty accidents happening again, which can be linked to changes in their body or cognitive health. Stay patient and talk with your vet if things shift dramatically.

What You Can Do to Help

Aging doesn’t mean your Shih Tzu is slowing down for good—it just means they need a little more support from you. With the right care, their senior years can still be full of love, comfort, and plenty of tail wags. Focus on regular vet visits, soft cozy spots to rest, light movement, and a diet that supports their changing body. And yes, there are products made just for this stage of life:
