Dr. Lisa Lippman
, a celebrity veterinarian and director of virtual medicine at Bond Vet
, suggests keeping Benadryl on hand if it's the basic and classic kind.
"The active ingredient should be diphenhydramine HC only,"
Lippman told HuffPost. "Benadryl now makes a cold formula that has acetaminophen in it, which is toxic to pets."
Freyer said that Benadryl is good to have ready for any surprise allergic reactions your pet may have, but to always check with a vet before administering it.
"You never know when your pup might be stung by a bee or other insect, or might react to something in its environment," she said. "Make sure to discuss with your veterinarian before giving any medications to your pet."
