I could care less about American Hefeweizen. Make a seperate article, this is about Hefe in general. I'd like to add Granville Island Breweries to the list, but lo and behold, it's a list of American brands, and GIB is Canadian. Go figure.
The standard dosage for oral Benadryl is 1 mg per pound of body weight, given 2-3 times a day. Most drug store diphenhydramine tablets are 25 mg, which is the size used for a 25 pound dog. Always double check the dosage before giving an over the counter medication. In addition, many formulations are combined with other medications such as Tylenol so make sure Benadryl tablets contain only diphenhydramine.
Weigh your dog. Your dog will take 1 mg to 2 mg of Benadryl per lb. of body weight. This means, for example, that if your dog weighs 25 pounds, the pet can have 25 mg to 50 mg of Benadryl. Roll the Benadryl pill in peanut butter. Offer the peanut butter-coated Benadryl to your dog, as you would a treat.
