I am going through the same thing with my pug Eli. I didn't have the money to do a ultrasound but his bladder is definitely deteriorating. The Vet says his bladder has calcium build up in the walls of his bladder>He has a neurological problem in his spine that is causing weakness in his back legs and incontinence and UTI's, some that are resistant it seems every other week. He is in diapers and was on Prednisone since September and two different bladder medications Bethanacol and Phenoxybenzomene to help empty his bladder. We switched him to dexamethasone recently when we thought the Prednisone wasnt doing it anymore and it seemd to help but how long can he stay on that without complications? I have had to have him catheterized several times He has blood and mucus sometimes along with the specks of calcium that block his ureter >It is getting very costly but I don't have the heart to put him down yet as he is still his HAPPY self. He is only 11 and weighs 26 lbs now (he was 30) He still can walk and even goes down the steps himself on good days but I watch so he doesn't get weak and fall.
I am trying to find something to help dissolve calcium! I have known that Apple Cider Vinegar will do it. I am looking for anyone that has other suggestion.
I have taken him off of his OLD dog food (Pedigree) and switched to Evangers grain free but giving him lots of cabbage and kale and carrots for snacks. I'm going to give him some liver for iron for the bleeding and add some canned pumpkin to his diet to make sure he doesn't get constipated. Im going to give him the Apple cider vinegar for the calcium build up with some cottage cheese and honey. At this point it is worth a try.
Like you I am trying to just stretch out his days and give him lots of love. I keep praying on him for a miracle but know I will have to face that day when I know he can't go on anymore. Until then I keep Trying!
