Is My Shih Tzu Dying? Emergency Signs and End-of-Life Changes
How we researched this guide: This article is based on guidance from the American Animal Hospital Association (AAHA) and VCA Animal Hospitals, including the HHHHHMM quality-of-life scale developed by veterinary oncologist Dr. Alice Villalobos. It is not a substitute for an exam. Last reviewed: September 2026.
Noticing that your Shih Tzu is not acting like themselves is frightening. Some changes mean your dog needs a vet today. Others are slower signs that an older or chronically ill dog is nearing the end of life.
This guide helps you tell the difference. It covers emergency warning signs, gradual end-of-life changes, and how vets help families judge quality of life. If you are worried right now, call your veterinarian or an emergency clinic first.
Go to a vet or emergency clinic now if your Shih Tzu: is struggling to breathe, collapses or cannot stand, has a seizure, has pale, gray, white, blue, or purple gums, has a swollen or bloated belly, keeps vomiting or has ongoing diarrhea, is bleeding or was injured, or suddenly stops responding to you. These are among the emergency signs listed by the American Animal Hospital Association.
Emergency Signs: When a Shih Tzu Needs Help Today
Sudden, severe changes can be life-threatening at any age. AAHA lists these signs as reasons to seek immediate veterinary care:
- Difficulty breathing. Gasping, wheezing, or unusual panting. Shih Tzus have short, flat faces, so breathing trouble can become serious quickly. See our guide to Shih Tzu breathing problems.
- Persistent vomiting or diarrhea. Small dogs can dehydrate fast. Our vomiting guide explains the warning signs.
- Unresponsiveness or disorientation. Being unusually lethargic or not responding to your voice.
- Seizures. Uncontrolled shaking, drooling, or loss of consciousness.
- Bleeding or injury. Any visible bleeding or known trauma, such as a fall.
- Sudden behavior changes. New aggression, fear, or hiding.
- Swelling or bloating, especially of the belly.
- Pale or discolored gums. Healthy gums are usually pink.
- Eye injuries. Shih Tzus have prominent eyes that are easy to injure.
- Sudden weakness or paralysis.
Gradual Signs That a Shih Tzu May Be Nearing the End of Life
Shih Tzus often live into their teens. A large UK study found a median age at death of about 12.7 years for the breed, so many families care for a senior Shih Tzu for several years. You can read more in our Shih Tzu lifespan guide.
VCA Animal Hospitals notes that dogs approaching the end of life often have chronic conditions such as kidney disease, cancer, dental disease, or arthritis. Common changes include:
- Eating very little or refusing food
- Drinking less, or much more than usual
- Trouble getting up, walking, or using stairs
- Accidents in the house or trouble keeping clean
- Withdrawing from the family and losing interest in favorite things
- Labored or noisy breathing at rest
- More bad days than good days
These signs do not always mean the end is near. Many can be treated or managed, especially pain. That is why a vet visit matters, even for an older dog. Our senior Shih Tzu care guide covers everyday comfort for aging dogs.
How Vets Assess Quality of Life: The HHHHHMM Scale
Many vets use the HHHHHMM scale, created by veterinary oncologist Dr. Alice Villalobos, to help families look at quality of life more clearly. Each area is scored from 1 to 10. According to VCA, a score above 5 in each area, or a total above 35, suggests an acceptable quality of life.
| Area | What to ask yourself |
|---|---|
| Hurt | Is pain controlled? Can my dog breathe comfortably? |
| Hunger | Is my dog eating enough, even with help such as hand-feeding? |
| Hydration | Is my dog drinking enough, or do they need fluids from the vet? |
| Hygiene | Can my dog stay clean and free of sores and matted coat? |
| Happiness | Does my dog still show interest, make eye contact, or wag? |
| Mobility | Can my dog move around enough to be comfortable? |
| More good days than bad | Are bad days starting to outnumber good ones? |
It can help to keep a simple calendar and mark each day as good or bad. Bring it to your vet visit. It gives you both a clearer picture than memory alone.
What Your Vet Can Do
AAHA explains that your veterinary team can help you build a plan for your dog’s final stage of life. That plan may include:
- Palliative or hospice care to relieve pain, nausea, and other symptoms at home.
- Pain assessment of eating, drinking, breathing, moving, and toileting.
- Guidance on euthanasia. AAHA describes humane euthanasia as designed to be peaceful and painless. Your vet can explain the process and help you decide when the time is right.
There is no single right time, and it is normal to feel unsure. Talking openly with your vet about your dog’s comfort is the kindest step you can take.
Caring for Yourself
AAHA notes that grieving the loss of a pet is normal and natural. Many vets, animal hospitals, and veterinary schools offer pet loss support resources. Reaching out for support is a healthy step, not a sign of weakness.
