An 8 year old Lhasa Apso that seemed perfectly healthy. I asked the doctor why it was being euthanized and he said he didn't know. He seemed totally unphased by having someone come in and say they want to euthanize their pet. He's been practicing longer than I've been alive (and I'm not particularly young). I hope to never reach that point. It was still bothering me later so I went back and read the patient's history. Nothing was really listed except the adoption papers from the animal shelter were in there. It had been returned to the shelter several times. I'm guessing it had an insurmountable behavioral issue going on.
