At Pups’n’Pets, we believe that informed owners are the best defense against preventable emergencies. While many health issues in dogs are manageable, there are several serious medical conditions that can become fatal if not recognized and treated promptly. This page is dedicated to helping dog owners understand the warning signs of these conditions so they can act fast and protect their pets.
1. Gastric Dilatation-Volvulus (Bloat)
What it is:
Bloat occurs when a dog’s stomach fills with gas, food, or fluid and twists upon itself, cutting off blood flow and trapping contents. It’s most common in large, deep-chested breeds but can affect any dog.
Signs to watch for:
- Swollen or tight abdomen
- Dry heaving or retching with no vomit
- Restlessness, pacing, or panting
- Drooling excessively
- Collapse or signs of shock
Why it’s deadly:
Bloat can kill within hours. Immediate emergency surgery is often the only option for survival.
Prevention tips:
- Avoid vigorous activity before and after meals
- Feed smaller, more frequent meals
- Use slow feeders for dogs who eat quickly
2. Heatstroke
What it is:
Heatstroke happens when a dog’s body temperature rises to dangerous levels, usually due to hot weather, overexertion, or being left in a hot vehicle.
Signs to watch for:
- Excessive panting or drooling
- Red or pale gums
- Vomiting or diarrhea
- Weakness, collapse, or seizures
Why it’s deadly:
Organs can shut down quickly if body temperature isn’t reduced. Dogs cannot regulate heat as effectively as humans.
Prevention tips:
- Never leave dogs in cars, even for minutes
- Provide constant access to shade and water
- Walk dogs early or late in the day during hot weather
3. Canine Parvovirus
What it is:
Parvo is a highly contagious viral disease that primarily affects puppies and unvaccinated dogs. It attacks the gastrointestinal tract and immune system.
Signs to watch for:
- Severe, bloody diarrhea
- Vomiting
- Lethargy and loss of appetite
- Rapid dehydration
Why it’s deadly:
Without aggressive veterinary care, parvo can kill within days. It’s especially dangerous for young puppies.
Prevention tips:
- Ensure your dog is fully vaccinated
- Avoid dog parks and communal areas until vaccines are complete
- Disinfect areas where infected dogs may have been
4. Pyometra
What it is:
A life-threatening uterine infection that affects unspayed female dogs, usually occurring weeks after a heat cycle.
Signs to watch for:
- Lethargy and vomiting
- Vaginal discharge (may be absent in closed pyometra)
- Distended abdomen
- Increased thirst and urination
Why it’s deadly:
If untreated, the infection can spread rapidly through the bloodstream. Emergency surgery is often required.
Prevention tips:
- Spay female dogs who are not intended for breeding
- Monitor behavior closely after heat cycles
5. Toxin Ingestion
What it is:
Dogs can be poisoned by common substances such as chocolate, xylitol (in sugar-free gum), grapes/raisins, certain plants, human medications, and antifreeze.
Signs to watch for:
- Vomiting and diarrhea
- Tremors or seizures
- Irregular heartbeat
- Lethargy or collapse
Why it’s deadly:
Many toxins act fast and affect the liver, kidneys, or nervous system.
Prevention tips:
- Dog-proof your home and yard
- Store all food, medicine, and chemicals safely
- Be aware of toxic plants and human foods
