Senior dog can't stand, pees herself, and is miserable. Euthanasia?

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

If she is in pain despite medication, unable to mobilise and also incontinent then yes, euthanasia should definitely be considered to prevent further pain and discomfort (such as infected bed sores etc). The cold limb is also a red flag for reduced circulation such as from a clot and is extremely painful in itself. Recovery is very unlikely and delays would add further suffering and pain

I'm sorry your dog isn't doing well! I would be concerned that she may be in pain, and she could have a neurological problem causing her inability to walk. It's quite serious that she hasn't eaten for four days and can't get up. I work for a home euthanasia service, so I frequently encounter the question of when to put an animal to sleep. I always recommend looking at the dog's quality of life. When a dog can't stand up and isn't eating, their quality of life has declined to a point where humane euthanasia should be considered. She will be starving from not eating, and that will be painful to her. It's also probably distressing she can't get up. In this case, I personally don't think it would be fair to wait it out. You can have her seen by a vet tomorrow to see if there are pain medications to give her to see if that helps her get up and medications to stimulate her to eat. If those don't work, then letting her go peacefully is the most kind option for her. I'm sure that's not something you want to hear, and I'm very sorry that she is doing so poorly.

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

Oh no, I'm so sorry that Santeri is so sick! I work for a home euthanasia service, so I face this question all the time with my clients. I suggest making a list of five things Santeri loved to do. If he's not doing at least two of them, then his quality of life has decreased to a point where humane euthanasia should be considered. It's always a hard decision to make, but if he has a poor quality of life, letting him go peacefully would be a great kindness.

Otherwise, I hope my answer helps and I'm sorry you are facing this issue :-(

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.

There are many possible reasons for incontinence and a basic physical exam can be useful to check for arthritic changes which may be contributing and treatable. If no obvious reason is found euthanasia may be worth considering as invasive tests and work up although providing diagnosis may not uncover treatable causes and quality of life can quickly slide in such patients
