Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. You can give 1 mg per pound of body weight. So if Luci weighs 100 pounds, she can get 100 mg of Benadryl. This may make her drowsy, however. I recommend using a monthly flea preventative medication such as Frontline or K9 Advantix. I hope this is helpful!
