What is Itchy Skin in Dogs?

Itchy skin, also known as pruritus, is a common issue in dogs that can indicate multiple underlying health problems. Persistent scratching, licking, or chewing can lead to skin infections, redness, and discomfort. If left untreated, chronic itching may require lifelong management.

Pruritus can affect specific areas or the entire body. Since it may be caused by allergies, parasites, infections, or immune disorders, a veterinary consultation is essential to effectively diagnose and treat the root cause.

Dogs suffering from itchy skin may exhibit the following symptoms:

• Excessive scratching or biting

• Hair loss (alopecia)
• Constant licking, often leading to red-brown saliva stains
• Chewing of paws

If your dog displays any of these signs, consult a vet to prevent further complications.
