Hi Jeni, you ask a great question and Abbie is so lucky to have you thinking about this.

You are right, every dog is different. The thing to ask yourself is, what were her weight, fitness level and activity amounts like pre-surgery? The more fit a dog prior to amputation, the more strength and stamina they can have later after recovery. All dogs will definitely benefit from appropriate exercise that can help build strength and stamina though. 

We have a number of great videos you can watch with experts who talk about this very thing. Here's a couple of good ones to start:

Do Dogs “Self-Limit” Their Activity? Or Are They in Pain?

How To Prevent Common Injuries in Tripawds

Our e-book, Loving Life On Three Legs , also talks a lot about strength and stamina.

You really want to start reintroducing exercise slowly and carefully. You'll know you've pushed her too hard if she is reluctant to continue playing, sits down on walks, sleeps hard afterward, or shows pain signals common to all dogs.

Here's a little something we wrote, about things we wish we had known when our Jerry lost his leg:

Tripawd Health Tips to Avoid Injury to Remaining Legs

There is no telling what a dog is capable of without a full assessment by a credentialed canine rehab therapist though. I would love to try to find one closer to you, I can often find a therapist for people when they don't think anyone is nearby. Message me and I'll do my best! That way you can take advantage of the Tripawds Foundation program which can pay for your first rehab visit .

If we can't find one for you, you may also want to check out Dr. Debbie Torica's course:

I hope this helps!
