Can you give a 14 lb dog 1 tsp liquid Benedryl?

Yes, you can give a 14 lb dog liquid Benadryl, but it's essential to consult your veterinarian first for the correct dosage and safety. The general dosage is 1 mg of diphenhydramine per pound of body weight, so for a 14 lb dog, the typical dose would be around 14 mg, which is roughly equivalent to 1 teaspoon of the liquid formulation (check the concentration). Always ensure that the formulation is free of harmful additives like alcohol or xylitol, and monitor your pet for any adverse reactions.
