My husband called me at work one day to say that when he walked in the door from work, he almost didn't recognize Max, our yellow lab. He said "you need to come home right away" and I did. My poor boys head was so swollen, his eyes were like slits. I had some benedryl in the house and gave Max one, then we rushed him to a 24 hour a day animal hospital. They rushed him and started treating him right away. The vet asked what had happened and we said we weren't sure, there wasn't any change of food or different medicine or anything like that. We did have some ground bees in the backyard and the only conclusion we could come to was that he had eaten some of them. The vet told me to keep benedryl in the house all the time and told me that you could give so many (I can't remember the amount) benedryls per 10 pounds of body weight, I believe. Max weighed 90, 95 pounds and whatever the dosage was, it came out to an incredible amount of benedryl. The one little pill I gave him didn't really help very much. Anyway, Max recovered and was fine, but it was awfully scary.
