Dog Health Symptoms Guide: 23 Warning Signs

The most common life-threatening emergencies include bloat (GDV), which can kill within hours if the stomach twists; heatstroke, especially in brachycephalic breeds; and venomous snake bites. Other emergencies include severe bleeding, difficulty breathing, seizures, and ingestion of toxic substances. If your dog shows signs of any emergency, contact your veterinarian or an emergency animal hospital immediately.

Dogs often hide pain, but common signs include limping or reluctance to move, whimpering or yelping when touched, excessive panting or drooling, loss of appetite, restlessness or inability to get comfortable, aggression or withdrawal, excessive licking of a specific area, and changes in posture such as a hunched back. Subtle signs like decreased activity or changes in sleeping patterns can also indicate pain.

Seek immediate veterinary care for: difficulty breathing, uncontrolled bleeding, suspected bloat, seizures, inability to urinate, or suspected poisoning. Schedule a same-day visit for: bloody stool, persistent vomiting or diarrhea lasting more than 24 hours, sudden eye swelling, or refusal to eat for more than 2 days. Monitor at home for: occasional stomach gurgling, mild sneezing, or minor limping that improves.

Yes, regular professional grooming is one of the best ways to catch health problems early. Groomers handle every part of your dog and are often the first to notice lumps or masses, skin changes or rashes, ear infections, dental problems like broken teeth or inflamed gums, parasites such as fleas and ticks, eye discharge or cloudiness, hair loss patterns, and changes in skin texture or color.

A dog first aid kit should include: a digital rectal thermometer (normal dog temp is 101-102.5°F), gauze pads and rolls, adhesive tape, hydrogen peroxide 3% (to induce vomiting only when directed by a vet), sterile saline solution for flushing wounds or eyes, tweezers for tick or splinter removal, a muzzle (injured dogs may bite), an emergency blanket, styptic powder for nail bleeding, diphenhydramine (Benadryl) for allergic reactions at a vet-approved dose, and your veterinarian's phone number plus the ASPCA Poison Control number (888-426-4435).

To check your dog's vital signs: Temperature -- use a digital rectal thermometer; normal is 101-102.5°F. Heart rate -- place your hand on the left side of the chest behind the elbow; normal is 60-140 beats per minute depending on size. Breathing rate -- count chest rises for 15 seconds and multiply by 4; normal is 10-30 breaths per minute at rest. Gum color -- press on the gum and release; it should return to pink within 2 seconds (capillary refill time). Hydration -- gently pinch the skin on the back of the neck; it should snap back immediately in a well-hydrated dog.
