This is Gus:
Gus is a nearly 2-year-old American Bulldog. He enjoys walks, playing at the park, and food. Lately, he also enjoys severe allergic reactions caused by unknown stimuli:
It has happened twice now, both within the last week. His face swells like a balloon, and he develops a serious hives on his legs and neck. A shot of antihistimines at the vet has solved the problem both times, but that's a rather expensive trip to take regularly.
I have no idea what is causing these reactions, but it doesn't seem to be food. The vet seems to think it might be spider bites, but we haven't seen any spiders around the house. Have any MGoDog owners experienced anything similar? Any advice? Preferably advice that does not involve anal glands?
