Looks like our first Minnesota fall is going to be filled with dog allergies! YAAAAY Frodo is showing signs of seasonal allergies and I was looking for some suggestions to make this season a little easier on him. I have him on a rabbit based diet, which in Chinese medicine is supposed to cool down the system. I figure it is worth a shot. I know you can give dogs benadryl, how often is that okay and how much for a 30 pound dog? If anyone else has any other suggestions it would be much appreciated.
