How much benedril can i give my 12 pound dog before a plane flight?

For a 12-pound dog, the typical dosage of Benadryl (diphenhydramine) is about 1 mg per pound of body weight, given every 8 to 12 hours. This means you could give approximately 12 mg for a single dose. However, it's crucial to consult your veterinarian before administering Benadryl to ensure it's safe and appropriate for your dog's specific health needs and to confirm the correct dosage. Additionally, consider any potential interactions with other medications your dog may be taking.
