1. Canine Parvovirus

Parvo is a highly contagious and often deadly viral disease, especially in puppies. It spreads through contact with infected feces and can survive on surfaces for months. Symptoms include severe vomiting, bloody diarrhea, lethargy, and fever.

Prevention: Vaccination is critical. Puppies should receive a full vaccination course, and boosters should be maintained throughout adulthood.

2. Kennel Cough

Also known as infectious tracheobronchitis, kennel cough is a respiratory infection caused by a mix of bacteria and viruses. It’s common in dogs who visit groomers, kennels, or dog parks.

Symptoms: Persistent, dry hacking cough, runny nose, sneezing, and mild fever.

Prevention: The Bordetella vaccine helps, especially for dogs in high-risk environments. Keep your dog away from sick dogs and monitor closely after boarding or daycare.

3. Canine Distemper

This serious viral illness affects the respiratory, gastrointestinal, and nervous systems. It’s often fatal in unvaccinated dogs and spreads through airborne exposure or shared bowls.

Symptoms: Discharge from eyes and nose, coughing, vomiting, diarrhea, seizures, and paralysis in later stages.

Prevention: Core puppy vaccinations protect against distemper. Boosters are essential to maintain immunity throughout life.

4. Lyme Disease

Lyme disease is caused by bacteria transmitted through tick bites. It can affect the joints, kidneys, and heart if untreated, and is becoming more common due to rising tick populations.

Symptoms: Limping (often shifting from leg to leg), fever, fatigue, swollen joints, and loss of appetite.

Prevention: Use tick prevention year-round. Check your dog for ticks after walks, especially in wooded or grassy areas. A Lyme vaccine may be recommended in high-risk zones.

5. Canine Diabetes

Like humans, dogs can develop diabetes mellitus when their body can’t properly regulate blood sugar levels. It’s more common in older dogs and certain breeds like Dachshunds and Poodles.

Symptoms: Excessive thirst, increased urination, weight loss despite normal appetite, lethargy, and cloudy eyes.

Prevention: There’s no guaranteed prevention, but maintaining a healthy weight and balanced diet can lower the risk. Early diagnosis and insulin treatment can manage the condition effectively.

For many owners, yes. Chronic illnesses and emergencies can be expensive — insurance may help you say yes to the best care without financial strain.
