Common Skin Problems in Dogs and Cats

·

Itching, hair loss, allergies, parasites and skin infections are common concerns for dogs and cats. Understanding the signs and knowing when to seek veterinary care can help protect your pet's comfort and overall wellbeing.

Persistent Itching

Frequent scratching, licking or chewing can indicate an underlying skin concern.

Hair Loss

Bald patches or unusual coat changes should be discussed with your veterinarian.

Redness & Irritation

Red, inflamed or irritated skin may have several possible causes.

Skin Infections

Odour, discharge, crusting or sores can require veterinary evaluation.

Itching and Skin Discomfort

Persistent itching can affect your pet's comfort, sleep and daily routine. Dogs and cats may scratch, lick, chew or rub affected areas. Itching can have different causes, including allergies, parasites, infections and other skin conditions.

Hair Loss and Coat Changes

Hair loss or changes in the coat can occur for many different reasons. You may notice thinning fur, bald patches, excessive shedding, changes in coat texture or areas where your pet has been licking or scratching repeatedly.

Keeping track of when the change started and whether it is getting better or worse can provide useful information for your veterinary team.

Allergies and Skin Problems

Allergies are one possible cause of recurring itching and skin irritation in pets. Environmental sensitivities, food-related reactions and flea allergy can all present with skin or coat changes.

Because similar symptoms can have different causes, a veterinary examination can help determine what further evaluation may be appropriate.

Parasites and Skin Infections

Fleas, mites and other parasites can cause itching, irritation and hair loss. Bacterial or fungal infections can also affect the skin and coat. Signs such as redness, crusting, unusual odour, discharge or sores should be discussed with your veterinary team.

When Should Your Pet Be Examined?

Consider contacting your veterinarian when skin symptoms persist, return frequently or appear to be causing your pet significant discomfort. Early evaluation may help your veterinary team determine the appropriate next steps.

What You Can Observe at Home

Before an appointment, note when the symptoms started and whether they are seasonal or continuous. You can also observe changes in appetite, activity, grooming behaviour, sleep, coat condition and the location of affected skin.
