Canine atopic dermatitis (environmental allergies) affects an estimated 10–15% of all dogs. It causes chronic itching, skin infections, ear infections, and discomfort. Treatment ranges from $30/month for basic management to $1,000+/month for severe cases requiring multiple treatments. Finding the right combination for your dog's specific allergies is key.
The average cost of dog skin allergy treatment is $50 to $200 per month for ongoing management, with initial diagnosis and treatment setup costing $200 to $1,000.
