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.
Giving your dog Benadryl can help relieve a number of symptoms. Although it can be a useful medicine it's a good idea to check if it will be suitable for your dog before giving it to him. Benadryl is originally designed for humans and too much could be harmful to your dog. Therefore, it's also important to make sure you have the correct dosage for your dog's weight. Generally, the recommended dosage of Benadryl is 1mg per 1lb of your dog's weight. It should only be given to your dog every 8 hours.
