Hi Ronnie,

Thanks for joining us, your future posts won't need approval so post away.

Tell us a little more about your dog, like his age, breed, and why he lost his leg and how long ago. Every dog's story is different when it comes to their fitness level and the more you can tell us the more we can try to pinpoint what's going on so that if you do take him to the vet you can have some background info together.

One thing to keep in mind: Tripawds need core strengthening exercises before they can build endurance. It's like how we humans need strong abdominals, back and leg muscles before we can do any kind of real running. If your pup hasn't had these types of exercises before, he will need to get strong in the core before he can run run run.

When a dog sits down during a walk, play or exercise, it means they need a break. For Tripawds, it's even more of a sign that they've probably overdone things and need some real R&R over a few days to recover. How long are your walk/play sessions? Rehab experts tell us that Tripawds need shorter walks (10-15 min), 2 or 3 times a day. Longer walks are not beneficial and may do more damage.

I know it's a lot to think about! For your dog's long term health and lots of exercise tips, check out our ebook, Loving Life on Three Legs.

Stay tuned, more folks will chime in shortly.
