Yes, I forgot if Marty is on any supplements?
The backend "lifts" have long handles, but seem awkward for both dog and owner. Maybe a sturdy leash and a good harness, keeping it tight when he pees, would give enough support, or at least some? My folks both have mobility problems, so I'm trying to think what they might be able to use...I know at training, I can use the leash to lift jazz up some (she is 20 lbs), and I use a comfort flex harness on her, though it does support the front more than the back ( http://www.cleanrun.com/index.cfm?fu...roduct_ID=1771
In the US, I have used Care Credit, which has allowed me to charge and pay off interest free. It has helped me with these bigger unexpected dog expenses, mine or family member's. Even if it's available where you are, your vet has to use it, so maybe something worth asking the vet?
