My oldest dog got sicker and sicker. He would either not eat the food or throw it up. Last Thanksgiving Day, after we returned home from visiting relatives, he was nearly comotose.
You're really lucky, because this toxic stuff damages the kidneys, which don't heal to well. It makes crystals made of melmaine and cyanuric acid that tear the kidneys up and cause scaring. You caught this just in time.
We have been trying to figure out why our cat has deteriorated rapidly, starting late last August. The recall only reports stuff from November, but I have my doubts. When this was finally mentioned on the media, we tried to feed him just about anything else, mostly meats. He would eat some tuna but not much else. He had gotten hooked on the carbohydrate rich pet food so he went on a hunger strike. The trouble is he didn't even protest, which he always did when his bowl wasn't full. He had gotten to where he didn't much care. Finally, he turned his nose on any food we offered and he went hunting.
He's pretty good at catching mice since he's a stray and he went back on the prowl. He's perked up quite a bit in the last two weeks. He's finally grooming himself again. He was getting all matted. The vet tested him for cat AIDS and feline lukemia, he looked so poorly. We feel very lucky he's bouncing back. We found an organic food that's not supposed to have any of these protein powders in it.
