I took him to a closer vet to have him euthanized after he deteriorated over the course of the day; he was clearly hungry but could barely eat and seemed to be groaning when he tried. He listened to his lungs beforehand and said afterward that it was probably lung inflammation (i.e., pneumonia?) I don't understand why his initial vet didn't inject him with an antibiotic. Seems like, if we were going to make the effort to try to save him and his lungs sounded like they had fluid, that we would want to give him one. He also said that since he had wry neck (from an ear infection two years ago) that he was probably prone to other things going wrong.
I am kicking myself for leaving the vet without confirming that he'd gotten the antibiotic and not getting a take-home prescription for them. I have called them and talked to a receptionist who confirmed that he wasn't given antibiotics and that the doctor's instructions didn't include them, and am awaiting a call back from that vet.
Does this sound like medical error to anyone else?
Unfortunately, she was right that I should have put him down sooner rather than later.
I switched to this hospital for its small animal/exotics vets (switched from a bird and exotic hospital that missed my guinea pig's UTI), but it looks like the female vet doesn't specialize in small animals or exotics at all! She told me she has seen a lot of guinea pigs in the condition that mine was in, and that they nearly all died shortly after being seen.
The vet who euthanized the pig supposedly specializes in small animal medicine. He had a much better bedside manner.
What is the difference between small animal vets and exotic vets? Am I supposed to seek out exotic vets?
