I have a very old, medium-sized dog. 35 pounds now. He used to be heavier, around 50 lbs., when he was younger and healthier. He got to the point he wouldn't sleep much at night, so our vet gave us acepromazine. Some time later, he gave us Gabapentin to help give him some rear leg function. When the Gabapentin wasn't doing the job, he added Prednisone. I didn't notice anything with the acepromazine or Gabapentin, particularly, but his head has swollen up, with one eye shut altogether. He has no appetite and is very lethargic. He is also taking Tramadol for pain. Can Prednisone or Tramadol cause this? If not, what do you suspect it could be? We are taking him to the vet first thing in the morning, but want to do what we can now.
OK. He's 16 years old. I wonder what could be causing it.
Poor thing. Maybe that's it. OK. Thanks!
