All started back in March and back and forward to the vet as my big boy was having problems weeing. Fast forward to last weekend and he'd stopped eating or drinking. He's now been at the vets for a week where they've drained his bladder numerous times, catheterised him numerous times, treated him for a secondary bacterial infection, given him diazapam to relax him . He has a spasm in his urethra. We've now been given the option of a risky operation that might not even work and even if it does work he'll be medicated for the rest of his life, he's only 4. After everything he's been through i just don't know what to do. He's my baby and it hurts me so much that nothing has helped him and that the only other option is putting him to sleep. At the moment he is eating and drinking and is a comfortable as he can be with a catheter so I'm wondering if his best option is to let him go peacefully. I know money shouldn't be an option but i really am struggling now. What would you do, I'm 80% sure of what I want to do but am I being heartless?
