What Makes Dogs Itchy & When to See a Vet

Possible Causes & Symptoms:

Below are the most common and possible causes and symptoms of skin itching in dogs.

Note: this information is not intended to replace the advice of your veterinarian. We encourage you to consult with a vet whenever possible before trying any products or if symptoms don’t improve.

Parasites (Fleas, ticks, and mites)

These are transmittable, tiny organisms found anywhere on your dog’s body. Parasites are most often found on the hind legs, the tail base, and the rear end.

Symptoms: excessive itching, loss of hair, vomiting, diarrhea, weight loss.

Food Allergies

Animals can develop allergies to specific foods, causing adverse reactions. The most common food allergies for dogs are chicken, beef, and wheat.

Symptoms: Excessive itching, stomach discomfort, vomiting, diarrhea, and lack of energy.

Skin Infection

The two most common skin infections that can affect our pets are yeast and bacteria.

Yeast infections look red and greasy and have a distinct odor. These usually affect areas of folded skin such as ears, neck, under the tail, or around your dog’s toes. Yeast infections often occur due to trapped water or allergens.

Bacterial infections can look pimple-like, or as dry patches of flaking skin. These affect any part of the body and should be treated immediately to prevent them from spreading. Bacterial infections often occur due to irritated or damaged skin.

Symptoms: Thickened skin, itching, hyperpigmentation, recurrent ear infections.

Contact Dermatitis

The two common types of dermatitis are either allergic or irritant contact dermatitis.

Allergic contact dermatitis occurs when the immune system develops a response. This is usually due to a harmless substance for those that are not allergic to it. Examples include food allergies and allergic reactions to non-harsh shampoo ingredients.

Irritant contact dermatitis occurs when the skin comes into contact with harsh substances. These usually cause damage or irritation to the skin. Examples include hash soap ingredients, essential oils, and chemicals found in grass.

Symptoms: Itching, inflamed patches of skin, scaling, fluid discharge

Hormonal Imbalances

Hormone balance affects almost every part of the body, including the skin. This happens your pet’s body does not produce enough of the thyroid hormone or puts out too much cortisol.

Symptoms: Itching, increased drinking and urinating, weight loss and gain, excessive panting


Symptoms of itching are also seen in dogs with psychological distress. Examples include boredom, anxiety, and even OCD compulsions.

Symptoms: Itching, urinating or defecating in the house, excessive barking, pacing.
