Which Internal Diseases are Most Common in Pets?

We treasure our pets as part of our households, like integral members of our families. However, just like our human loved ones, pets can occasionally fall ill. Unlike people, pets are unable to vocalize how they are feeling or if they are unwell. Thus, it becomes crucial for us, as pet owners, to be knowledgeable enough to identify signs of common internal illnesses in pets. Recognizing these signs and knowing what to do could save our pets’ lives.

Pet Health and Common Internal Diseases

Living creatures, our pets, can be victims of diverse health conditions. Owing to their internal nature, these diseases are not immediately visible to the naked eye, making them challenging to detect. As such, understanding these common internal diseases is paramount for every pet owner. Here they are:

  • Kidney Disease: Cats, more than other pets, are prone to kidney diseases. Recognizing frequent urination, increased thirst, appetite loss, and deteriorating coat condition can crucially signify kidney issues.
  • Heart Disease: Heart-related anomalies are not limited to humans; pets, particularly more oversized dog breeds, can suffer too. Symptoms include issues like persistent coughing, easy fatigue, and noticeable breathing issues.
  • Diabetes: Diabetes is a condition to which both cats and dogs are susceptible. These pets are perpetually hungry, urinate excessively, and lose weight despite their healthy diet.
  • Liver Disease: Playing a significant role in food digestion and detoxification, the liver is important in both humans and pets. Dogs and cats alike can come down with liver disease, leading to vomiting, decreased appetite, and a yellowish appearance of the skin or eyes.

Veterinary Internal Medicine and Internal Diseases in Pets

Veterinary internal medicine deals with understanding how pets contract diseases and developing solutions to treat them. In that capacity, preventative measures like dog vaccinations are a significant component of a vet’s work in safeguarding our pets’ health against certain diseases.

Pet Vaccinations

Administering vaccines to pets is a highly effective way to keep them healthy. They might not like the idea of injections, but its utility cannot be stressed enough. If an older dog is part of your family, and you’re looking for vet solutions for older dogs, always prioritize keeping them updated on their shots.

Veterinary Geriatric Care

Senior pets, like older humans, require a different healthcare approach. Veterinary geriatric care ensures older pets remain in a state of comfort and health. Here veterinary internal medicine shines, as it helps diagnose and treat multiple health issues related to old age.

Disease Prevention and Pet Longevity

The adage that ‘prevention is better than a cure’ holds particularly true when it comes to pet diseases. Early diagnosis also contributes to a longer, healthier life for pets. Here are some steps to ensure this:

  • Regular Check-ups: Ensure regular veterinarian check-ups for your pet. These visits can lead to early detection and treatment, thereby controlling any disease conditions.
  • Pet Immunization: Follow your pet’s vaccination schedule strictly. These vaccines help immunize your pets against numerous common diseases.
  • Healthy Lifestyle: A balanced diet, physical exercise, and emotional well-being ensure your pet remains in top health condition.

Changing Behavior in Aging Pets

When our pets get older, they might not act the same way they used to. These changes in behavior are often a sign that your pet is not feeling well. There are some important signs you should look for. Let’s discuss a few of these changes:

  • Reduced Activity: One of the easiest things to notice is if your pet is less active than before. This could mean that your pet is experiencing discomfort or even pain.
  • Disorientation: Sometimes, pets might start acting unusually when they’re not feeling well. They may appear confused or disoriented. This can often indicate a problem.
  • Increased Aggression: A pet that isn’t feeling its best might start acting grumpier. Some pets even show aggression when they are not feeling well or are in pain.

Each of these behavioral changes can be a sign that your pet requires more of your attention and possibly medical intervention. It would be best to seek medical advice from a veterinary professional if you see any of these signs.

Remember, regular check-ups can help spot these problems early. Timely treatment can help manage your pet’s discomfort and keep them in the best possible health.


Healthy and joyful pets are what every pet owner aims for. Understanding common internal diseases, their symptoms, and preventive measures can go a long way in securing this aim. Regular check-ups, vaccination regimes, and a healthy lifestyle can prevent many of these ailments. While the thought of pets getting sick is distressing, the reassurance of doing everything possible for their well-being is a source of solace. Let’s devote our best efforts to providing our pets with the best care possible!
