My baby Oscar(Chihuahua) has become an old man :( He started coughing a couple weeks ago. It was just an occaisional cough, and it started when a front came through; so, I thought it was just allergies; he IS a Chihuahua. It started to get more frequent and harder, so I called my vet. It was Friday and he couldn't see him until Monday. I live in a small town with only one vet, and he has to make a lot of farm calls. Well, he got to the vet today and was examined. It turns out he has heart congestion. Now, he has to be on lasix, a heart pill, and a salt free diet. Thank God for modern veterinary medicine. The funny thing is, today, we had to take my grandmother to the doctor and they took her OFF of lasix :rolleyes: Go figure, we take one old mammal off of one medicine and then have to put another one on the same thing :p He is already doing better. He's pee'd a lot and not coughing as hard. He's a little trooper :)
