Hi Madigan and folks, welcome! I'm so sorry about that horrible accident! Glad to know he's getting around alright. Keep in mind 3 weeks is not a long time, he will need time to adapt and get strong. But the good news is there is a LOT you can do to help him get there.

Yes, weight loss is critical. Every extra pound on a dog equals five pounds on a human, so the more he can get to his ideal weight the better he will move.

When a dog loses a rear leg they lose 50% of their ability to climb up stairs, run, and propel themselves forward. Yes, he is using his front leg for balance and to compensate. But you can help him with better habits, by having him evaluated by a canine rehab therapist. These experts can let you know how to strengthen and improve his stamina. Hint: it's not about strengthening the legs, but the core and back muscles. The best part is that Tripawds Foundation can pay for your first rehab visit so you have nothing to lose! If you want help finding a therapist please let us know.

Meanwhile, how is your house set up? If your floors are slippery, adding traction will make a huge difference. Keeping his activity scaled back and not allowing him to jump off high surfaces is also going to reduce his risk of injury.
