All About Dermatology

Pet dermatologists specialize in the treatment of skin issues that your pet may be dealing with. A dermatology office can also perform skin biopsies, allergy tests, and a variety of other tests to determine the cause of your pet’s problem. Maybe you notice that your cat or dog has irritation on their skin. Or maybe you notice a rash. Whatever the case, we can assist your pet here at Willow Glen Pet Hospital. We have locations in both Willow Glen and San Jose.


Signs to Look For

There are many signs that your pet may be experiencing a dermatologic issue. Here are some signs to look out for:

  • Repetitive rubbing of face or ears
  • Scratching that is excessive
  • Biting or chewing of the skin
  • Rubbing or scooting against surfaces or carpet
  • Irritated or red skin
  • Sores
  • Loss of hair
  • Dry, flaky skin

Most Common Pet Dermatological Conditions

Pets deal with skin problems just like people do. When skin problems arise, it can be very uncomfortable. Here are some of the most common skin conditions that affect both cats and dogs:

  • Allergic Dermatitis – This is common in both dogs and cats. Allergies cause redness and itching and lead to hair loss.
  • Cushing’s Disease – When a pet’s adrenal glands create too much cortisone, it results in Cushing’s Disease. Excessive appetite, excessive thirst, hair loss, excessive urination, and lethargy are common symptoms of this disorder. A vet will need to give your pet a urinalysis as well as blood work to diagnose this disease accurately.
  • Hypothyroidism – The most common hormone issue dogs face is hypothyroidism. Lymphocytic thyroiditis is a common cause of this disorder. Obesity, hair loss, and lethargy are common symptoms that your pet will experience. Both blood tests and thyroid tests are conducted to diagnose it properly.
  • Lick Granuloma – Allergic dermatitis, arthritis, and even neoplasia can cause lick granuloma in pets. Both stress and boredom may also result in lick granuloma. Excessive licking is normally present in pets with this condition.
  • Ringworm – This is probably the most common skin condition that pets suffer from. Hair loss and scaly patches will be present in pets that have ringworm. To get a proper diagnosis, tests will need to be conducted.
