Hello and welcome, your future posts will not have to wait for approval.

Not only do I have experience with small rear leg Tripawds, but my first lost her leg to a mast cell tumor.

Maggie was a little pug who's second MCT showed up in her left knee.  Because the tumor was into the knee tissue the whole leg had to come off.  Maggie took a little longer than most to get used to her new normal, but once she got there she hopped happily though life for almost 4 years.  You can read her story and about her amp and treatment in her blog, the links are in my signature below.

In general it is easier for a dog to lose a hind leg since they carry 60% of their weight on their front legs.  Maggie could do pretty much what she wanted after surgery, except her walking distance was about 1/2 of what it was pre-surgery.  I didn't learn until later that long walks are not the best thing for Tripawds, but Maggie being a lazy pug pretty much kept her walks short on her own!  One thing she lost was the ability to go up many stairs, she could go up two or three stairs without a problem.  At the time I lived in a single story house so the stair thing was not an issue.

My current rear amp Tripawd is a little pug mix named Elly.  She lost her leg at 7 months old after being hit by a car.  I adopted her when she was 10 months old, she will be 3 years old in December and has been a Tripawd for just over 2 years.  I now live in a split level house and Elly flies up and down the stairs.  She is smaller than Maggie was but younger.  Elly can do anything a dog her size and age can do, I have to reign her in sometimes.  Here is Elly's blog so you can see some of what she can do.

There are actually quite a few rear amps on this site, including our current Spokes-dog Wyatt Ray .  My friends the Oak Town Pack have 3 rear amp Tripawd GSDs!

Please let me know if I can help with any questions.

We have 6 out of 8 eyes

That might be something only a pug parent would get

I've had 3 pure bred pugs and while we haven't lost an eye I've been through 4 ulcerated corneas!

I'm guessing that once Texas Pete is healed up he will be back on squirrel patrol.  One of Elly's missions is to keep squirrel and cats out of our yard.  The other day I took Elly out into the back yard and we came around the house and almost ran into my neighbors cat! Elly chased him around to the side yard and followed the cat up a 3 foot high rock wall and up a short hill to the fence! 

The harness you are seeing is the RuffWear WebMaster, many Tripawds use them.  I've used them at one time or another for my last 4 small dogs.  Maggie the Tri-pug hated wearing hers and I didn't need it to get her around so she rarely used it, she wasn't nearly as active as Elly.  I love it for Elly, she never leaves the house without it.  She doesn't need help getting around at all, but I can help her balance and help her up and over things (she thinks she can do it herself!) and it's great when we work on balance and other exercises.  I an also help her into my truck with one hand (again, she thinks she is jumping in herself).  And when she sees a cat and goes into 'sled dog' mode I know she is not going to be able to escape the harness.

The downside to the WebMaster with small, big chested dogs is that the with the XS size the straps are long enough, but the harness itself is too long for the torso.  With the XXS size, which all mine have worn, the harness fits the body correctly but the straps are too short.  I have modified each of my harnesses by adding longer straps, however his voids the warranty.  Depending on Pete's measurements the XXS harness might fit him without modifications but you may not want to invest in a harness until Pete is healed and you see how he gets around.
