Hello, thanks for your question today! I am Dr. Drew, and I am a licensed veterinarian. I'll be happy to help you in any way I can.
I'm sorry to hear about Buckley's diagnosis.
unfortunately, the treatment options for such a condition, are quite limited, and unlikely to result in a cure.
if Buckley's quality of life has diminished, then humane euthanasia is definitely an acceptable choice,
to alleviate the discomfort and malaise that Buckley may be experiencing.
I think euthanasia is one of the kindest things we can do for our pets, in their time of need, if we cannot alleviate their symptoms by any other practical means.
