[When is the right time for euthanasia?]

Thank you all for the support and kind words. Avy went up to doggy heaven over the weekend. It was the right decision and he went peacefully 😔I am heartbroken, but I know he is running free with his buddies 

[When is the right time for euthanasia?]

I have been wondering if I will know when the right time will be for euthanasia. My 14 year old, Avy, has been incontinent of both bowel and bladder for quite some time now (at least 6 months). He is in a washable diaper almost constantly (it has an overnight poise pad in it, which he completely soaks), and a women’s depend diaper which he often soils (bowel) by the time I get home from work. I have talked to the vet, and he said that as long  as he does does not developed diaper rash or sore, it is fine. I try very hard to keep him clean and dry (baby powder, pinkxav, yeast cream, etc). He has loss of coordination/feeling in his back end, so he Cannot control when he goes. The vet does not believe he is in pain-but he is beginning to vomit occasionally (2-3 times a week), and drinks a TON of water. His kidney levels were a bit off the last time we checked, which has not been recently. Maybe kidney failure? He cannot go on very long walks because of his balance and legs. He cannot walk up the stairs any longer, and is becoming more  confused, and needy, especially at night (barks if he cannot see me, gets up and walks around to see what I’m doing). He does still becomes excited for food, (especially human food 😂) The constant diaper changing and cleaning up is frustrating and very time consuming, but I love him and would continue, but I want to make sure iM not doing this only for myself. I know being in a diaper 24/7 is not comfortable for him. I do not at this time have the option for someone to stay with him or take him out while I’m at work. He does this even when he is at home with me. 😢😔
He is a beautiful boy and I love him to pieces, but I absolutely do not want him to suffer.
