re: How do I know when it's time to put my dog to sleep? UPDATE

We put our 16 yo Jack Russell to sleep a month ago. Wife and I got her 2 months after we got married. It was a very hard decision, but a friend of mine who is also a vet, gave me some good advice. He said when your pet stops being a pet and becomes a patient, it's probably time to look at end of life options. He asked me what were my expectations of continuing giving her all these meds. He said we both know what the eventual outcome is going to be. Putting her down was extremely rough for wife and I. My kids said it was the first time they'd ever seen me that upset. Initially I felt guilty, but after a week or so I realized we made the right decision.
