Interdigital Cysts in Dogs: Signs, Causes, and Fast Relief

What Are Interdigital Cysts?

Interdigital cysts are painful sores that form in the webbing between a dog’s toes.

Also known as:

They often involve infection and are most common on the front paws.

Signs of Interdigital Cysts in Dogs

• Constant paw licking or chewing

• Red, swollen bumps between toes

• Hair loss in the webbing

• Bleeding, discharge, or pus

• Limping or difficulty walking

Early treatment helps prevent secondary infections.

Dogs with allergies, excess weight, or skin sensitivities are at higher risk.
