Should I put down my old dog with mobility and incontinence issues?

First off, I'm so sorry you had to say goodbye to Murphy. Please accept my condolences for your loss. You are right that vestibular disease isn't progressive, and it sounds like to me his symptoms were getting worse over time. To be honest, I think you did the right thing for him. It sounds like he had a pretty poor quality of life, and letting him go peacefully was a very kind thing to do, even though it was hard. Do not upset yourself thinking you put him to sleep wrongly, I think you made the right decision. Be kind to yourself.

I would recommend a full physical exam by your vet and a basic urine dipstick - some casues such as diabetes can be well managed with regular medication. If no treatbale causes are found you can discuss palliative care and euthanasia options with your vet. Although this can be a difficult decision, your vets will support you wjere it is the best course of action for Diamond

I am so sorry about Nubby. It definitely sounds like it is time for an exam/consult re: humane euthanasia with a veterinarian you are comfortable with. Yelping when moved, panting and shaking when at rest are likely signs that Nubby is in pain. Incontinence and inability to use her back legs are definite factors that diminish quality of life. Wishing you strength and love during this difficult time.

Yes, uti, kidney disease or diabetes are all possibilities. I would definitely consider euthanasia at this stage given her progressive conditions which are not going to improve and are becoming increasingly restrictive on her independence and quality of life

It is always a tough decision to say goodbye to a beloved pet but from your description, you made the right choice for him. His quality of life was poor, and you prevented him from suffering. I hope this helps!

Yes, euthanasia may indeed be a very valid option given the severity of his signs and limitations to his lifestyle. A blood screen may provide information as to the underlying causes and possible management options also

Yes, euthanasia is definitely a very valid option here, it is quite likely that inflammation in and around her spinal nerves is contributing to both the paralysis and incontinence and severely impacting her quality of life
