I had to take Fatboy in two Saturdays ago. He had his usual skin issues and was also showing signs of aspiration pneumonia. The vet prescribed him 500 MG of Cephalexin. He also received Aller-Chlor and cough tabs. Each were to be given once every 12 hours.
This treatment began the next day. He did fine on the medicines, but on Friday morning he threw up twice while I was getting ready for work. My husband said he would help clean up so I could take off for work on an early shift. About 10 minutes into my shift he called and sounded frantic; Fatboy had thrown up three more times. By this time his food was already gone, so it was mostly foam. He tried to get him to eat more food, but Fatboy wouldn't touch it. At this point we weren't sure if it was the medicines or the dog food as we had just bought a new bag of his normal kibble (maybe a bad batch?) Since we had planned a weekend getaway, we decided to not give him his medicine because we didn't want the car ride to make him sick. This was this past Saturday.
Yesterday I had given him his meds in the morning after he ate. He was fine. However his night time dosage scared us. I thought we were going to rush him to the emergency vet. He threw up (kind of expected this), but then his whole body started shaking. He looked scared. I took him outside and he pooped A LOT. It wasn't quite diarrhea, but it wasn't "ideal" either. After this he wouldn't move. I saw he had a little bit of foam coming out of his mouth. I had to carry him back upstairs. When he got inside he just stood there shaking. We opened all the doors to let the cold breeze flow through the house. He finally went to go lay down.
Throughout the time I checked to make sure he was breathing. He was thank God, but he just looked like he was going to pass out. He would not move at all. I tried to make him stand or sit up, but each time I lifted him to stand he would just collapse to the ground and close his eyes. His breathing stayed normal, but he just passed out asleep. I watched him throughout the night to make sure he was still breathing.
This morning he woke up perfectly happy. He did his normal booty wiggle when he saw I woke up. He ate all of his food, drank lots of water, and did his business outside just fine. Now that I'm home from work, he won't eat his food again. He wants to play, but until I take him back to the vet for his follow up this weekend, I don't want to overexert him until I know for sure he will be fine. Has anyone experienced this with Cephalexin? I read last night the antibiotic has not been approved for veterinary use, so this really worries me. I'm even more worried the bad reaction has possibly damaged his internal organs. Any thoughts/experiences would be greatly appreciated! Sorry for the long post, I just wanted to make sure I got in as much detail as possible.
