Yesterday my dog's face was all swollen up like a balloon and on the tip of his nose was two scratches that looked like a snake's bite marks that morning he was fine and like in 30 minutes he was so sore and pathertic looking he nearly gave me a heart attack I thought he had been bit by a rattler it would have been late in the year since the freeze came early but i've seen stranger things happen so i called the vet and drove like a maniac with my caution lights flashing it got to were his breathing got raspy and his eyes were swollen shut by the time I got to the vets at times driving 75 in a 35 mile an hour zone I was really panicking...2 hrs later after a steriod shot and a benedryl pill later and an 80 dollar vet bill later my baby was fine it turns out he is severely allergic to caterpillars which he happened to eat that morning!
