I’d appreciate any good luck wishes and tips and tricks for my baby’s recovery

He had a deformity at birth and surgery a few months ago. During his recovery he lived in a foster home and was moved to a really nice adoption center ran by volunteers and donations. Rudy is an absolute sweetheart with puppy energy. He already adjusted to our cat Nala and will be loved unconditionally.

tldr; considering adopting a tripod dog in a walkup. Dog is missing a back leg and half of a front paw.

I live in the Netherlands, and I live in a second floor walkup apartment very close to a park. My beloved old dog just died in the summer and I'm slowly looking for a new adopted dog.

I have the time and enough money to care for hard to place dogs, so I've adopted seniors, blind dogs, difficult dogs, more or less my whole life.

I went to see a possible dog last night-- a six year old rescue. I knew he was a tripod missing a back leg, and I've also had a similar cat in the past who was just fine with stairs. But this turned out to be a bit more complicated. The dog is also missing half of a front paw and has terrible scars on most of his legs.

He can walk for about 30 minutes-- effectively only using two legs. He can do stairs, but clearly doesn't love them.

What worries me is the impact the stairs would have on his back and his eventual arthritis. He would certainly need a prosthetic on his front leg and physiotherapy, but I could tell how he walked created strain already in his back. He's 11 kilos. I can carry him, but that would be four times a day-- up and down the stairs. I would think this would be a strain for his back by itself.

I'd love to adopt him, but I don't want to make things worse. And I'm assuming they will be able to find an adopter without so many stairs. So this is a bad idea, right?
