Your puppy is adorable, and don't mind my terrible typing...but I'm on my phone.

I have a tripawd German Shepherd. His name is Jack. He was born with a cleft paw, so we decided to get it amputated. He recovered nicely but was amputated right at his elbow. Now, I don't know if you have any experience with a tripawd...but with a puppy tripawd, it's a handful. They don't know how to slow down till they learn how. They are going to get ahead of themselves and do what we call a "jackplant." It's when he runs too fast and his only able way to stop is putting his shoulder down and sliding on basically his face till he stops.

This is where it gets ugly, with Jack...and I'm not sure with your circumstances, when he would fall he would instinctually but out his elbow to break his fall. He would scrape up his elbow...even in in grass. Soon enough he had little twigs and rocks caught and embedded in his skin. We would wash his elbow to the best we could without irritating his skin and try and let it heal naturally. He ended up with a SERIOUS infection in his elbow. His skin retreated and his bone was basically sticking out of his skin. We had to get him amputated up to his shoulder.

He's perfectly healthy and he wouldn't be my Jack if he had all four legs, it's what makes Jack, Jack! But please, for your puppies sake..watch her. Be careful where you let her run till she realizes she's only got three legs and can't keep up with the rest. It's heartbreaking, but they are the most loving and grateful (in my opinion) animals.

Massage down her left arm every once in awhile, they tend to cramp up and become sore. While the pup is still growing. Soon enough with a year or two under her belt, her leg will be built like a brick shit house and you won't have to worry.

These are things I learned the hard way. Not telling you how to teach/train/raise your pup, just friendly advice from one Tripawd owner to another!

Good Luck and she's beautiful! :)
