The common dog health problems that are faced by pets nowadays range from mild seasonal issues to chronic canine diseases that require long-term dog veterinary care.

Many common health problems in dogs begin gradually, and symptoms of dog illness often first appear harmless. Early detection of diseases depends on how consistently you observe patterns in eating, drinking, energy, and behavior. Most issues are manageable with attentive care and routine dog veterinary care.

Skin Allergies – Why Are These Among the Most Common Dog Health Issues?

Skin allergies continue to be among the most prevalent health problems in dogs worldwide. Initial symptoms usually come in mild dog illness forms, such as paw licking, scratching, or thinning of fur. Reactions can be due to food allergies, flea bites, environmental causes, and seasonal irritants.

What dog illness symptoms suggest a skin allergy?

  • Excessively chewing or licking your dog's paws
  • Redness around the dog’s tummy or ear area
  • Skin that appears dry or flaky (or irritated)
  • Frequent ear infections

Visiting the veterinarian regularly provides an opportunity to discuss potential allergens your dog may be exposed to, enabling you to avoid many of these problems before they become chronic.

Obesity and Canine Disease

Obesity is often viewed only as weight gain; however, it is also one of the most significant contributors to many serious diseases affecting dogs (and other pets). When a dog becomes overweight, numerous health-related issues associated with obesity arise; some examples of these health-related issues include, but are not limited to, diabetes, joint pain/injury, respiratory difficulty, and heart disease.

What are the early signs of obesity-linked health problems in dogs?

  • Reduced mobility
