If you believe your furry friend suffers from allergies, contact their vet. During your appointment, your pup’s veterinarian will likely recommend antihistamine medications, steroid medications, allergen-specific immunotherapy, or hypoallergenic shampoo. While your vet will administer the medication, it’s up to you to bathe your furry friend with the shampoo, which can be purchased at pet stores. Unfortunately, this task can be a little difficult if your pup despises bath time!
