What Are the Most Common Dog Diseases?

Dogs can be more than just a pet. They can be a companion, caretaker, teammate, and family. However, similarly to us, dogs can show fluctuations in their health status over time. Veterinarians have started to recognize a change in disease processes and trends as a result of the climate, urban lifestyles, and nutrition. By understanding the common dog diseases, an educated pet parent can gain better knowledge to help protect man’s best friend. So, what dog diseases in 2025 should you be aware of? Let’s take a look.

1. Tick- and Mosquito-Borne Illnesses,  Worrisome Common Dog Diseases

As global temperatures rise, ticks and mosquitoes are also better able to invade new areas, many of which may be amenable to foreign diseases on the backs of these new invaders. The most worrisome are:

• Lyme Disease – resembles flu symptoms like fever, joint pain, and severe fatigue
• Ehrlichiosis and Babesiosis – both blood-borne diseases transmitted by ticks
• Heartworm – an illness that is transmitted by mosquitoes during feeding of mosquitoes and can infect the heart and lungs.

👉 Tip for Pet Parents:

• Utilize year-round preventatives.
• Get annual screenings for parasites. 
• Avoid tall grass and always inspect your dog’s coat when returning from outdoor play.

2. Respiratory Illnesses: Beyond Kennel Cough

It is more commonly referred to as the tombstone cough, the Canine infectious respiratory disease complex. This strain is more viral and transferable, as well as harder to treat. CIRDC has the same symptoms as previously mentioned, such as a cough that will not go away, nasal discharge, and pneumonia in more severe cases.

👉 Prevention Measures:

• Get all vaccinations updated.
• Do not visit congested playgrounds and boarding houses when there are outbreaks.

This is one of the common dog diseases in 2025 that owners really need to pay attention to due to how quickly it spreads.

3. Food-Linked Health Issues & Obesity

Diet is critical to canine health, and ill choices will essentially result in:

• Dilated Cardiomyopathy (DCM) – shown to affect some grain-free or boutique diets; 
• Obesity – one of the most severe health problems today, which leads to diabetes, arthritis, and a reduction in lifetime.

👉 Preventative Actions:

• Select veterinarian-recommended diets. 
• Control food and treats.
• Provide daily exercise.

4. Skin Allergies and Atopic Dermatitis

Today’s environments expose your pets to allergens to a degree that has never been more favorable for the itchy, uncomfortable pet. Atopic dermatitis, in particular, is triggered by: 

• Dust mites
• Pollens
• Air pollution
• Food

👉 Options:

• Work with your veterinarian to determine your pets’ allergen triggers.
• Utilize medications prescribed by your veterinarian, such as Apoquel or Cytopoint.
• Regularly groom and bathe your dog to reduce allergens.

5. Genetic and Breed-Specific Disorders Among Common Dog Diseases

Purebred dogs can be stunning, but many also carry a risk of inherited issues. With time into the year 2025, here are some of the most common diseases in dogs: 

• Hip dysplasia – laxity of the joints, the larger the breed, the more apparent.

• Brachycephalic airway syndrome – breathing problems commonly seen in flat-faced breeds. 
• Degenerative myelopathy is a degenerative disease of part of the spinal cord. 

👉 What should you do: 

• Ask to see the genetic test results before you decide to buy a puppy.
• Receive regular orthopedic and neurological evaluations for the at-risk breeds.

6. Cancer in Dogs: Early Screening Advances

Cancer has been one of the leading causes of death in middle-aged and aged dogs. Fortunately, the situation is getting better due to the advances in early detection with liquid biopsy (blood tests), including more accessible options now available.

👉 Prevention and Care:

• Talk to your vet this year about annual cancer screens.
• Watch for signs of lumps, lethargy, and sudden weight loss.

Early diagnosis is transforming the approach to treating cancer at the forefront of the line among common dog diseases in 2025.

7. Canine Cognitive Dysfunction (Dog Dementia)

As dogs age, more will develop Canine Cognitive Dysfunction (CCD), similar to dementia in people, some signs of which are as follows: 

• Disorientation
• Pacing, or agitation at night
• Disrupted routines
• Increased anxiety

👉  Care Tips:

• Maintain routines as best as possible.
• Schedule at least yearly wellness exams, geriatric wellness exams when they can be scheduled.

8. Zoonotic Concerns: Leptospirosis & Rabies

• Leptospirosis – can occur by way of dirty water resources.
• Rabies continues to be a worldwide issue in some areas where dogs are compromised as stray populations.

👉 Prevention:

• Ensure that there are no missed vaccinations. 
• Discourage the dog from stagnant water.
