If your dog is allergic, you can use pet medicine containing diphenhydramine, chlorpheniramine and other ingredients. Due to the special nature of the medicine, you need to take the medicine under the guidance of a pet doctor to avoid damaging the dog's body.

The dog should be kept away from allergens, such as dust, pollen, etc., to the greatest extent possible. If your dog’s allergic symptoms are severe, such as laryngeal edema, difficulty breathing, etc., then you need to consult a pet doctor in time.
