How can I prevent my dog's environmental allergies and hives?
Hello, thank you for using Petco Pet Education Center, formerly Petcoach. Allergies are frustrating for people & pets. Unless you go for testing & a subsequent desensitization protocol, we really can not cure allergies. Almost all dogs will react to an allergen with skin symptoms, so your Brooklyn is showing typical signs. If the Benadryl seems to help, you can use it as needed. There are other OTC antihistamines available ( see petplace.com/antihistamine use in dogs ), but some of the best are available through your veterinarian. Apoquel, a pill you give daily, or as needed, and an injection called Cytopoint that will give Brooklyn relief for up to 2 months are now available. Otherwise, minimizing outdoor times when pollen counts are high, regular bathing in an oatmeal based shampoo in cool water, or even just wiping her down immediately after she comes in from outdoors will all help.
