Most cysts have a “secretory lining,” or a special lining that surrounds the entire cyst. False cysts don’t have this type of lining, and they only appear in dead tissue. Dermoid cysts are a rare type of cysts that a few pups develop before they’re born—chances are, this isn’t the kind of cyst your dog is dealing with.

Other causes could be abscesses, tumors, or allergies. Talk to a vet to determine the underlying cause.

You’ll probably find these cysts on your dog’s neck, torso, upper legs, or head.

You can clean the area with warm tap water or a warm saline mixture made with 1 tsp (5. 9 g) of salt and 2  c (470 mL) of distilled water. Don’t use any shampoo, soap, alcohol, hydrogen peroxide, or other substance to clean the area, unless your vet specifically suggests it. [12] X Research source

After the surgery, keep your pet in a quiet, closed-off area. Follow your vet’s after-care instructions; you may need to give your pup some special medication, or change their bandages regularly. [14] X Research source

Antibiotic regimens can last for at least 6 weeks.

Rhodesian Ridgebacks and Kerry Blue Terriers are more genetically likely to get dermoid cysts. Labradors, Cocker Spaniels, Poodles, and Schnauzers are also prone to cysts. [18] X Research source
