Yes-Ilsa had it done in March. She's a mix-about 47#. She actually was touching down the day after surgery and the day after that, when I picked her up, she was using it, jumped in the car and was jumping from front to back seat...yikes! Do not recommend that! She didn't do that once we got home though and she calmed down.
However, she is very stoic, has what seems to be a high pain tolerance and not that sensitivity to things.
BUT-here is what happened-after a while, she decided it was easier to lift that leg to walk/run and stopped using it.
THEN, I would leash her again and make her use it. So she would, until off leash, and then back to being a tripod! So I would yell to her-use your leg-and she'd put it back down. I thought we were doing well until I really looked and realized she was skimming the foot-so it wasn't actually touching down. She totally fooled me.
SO-I told the vet and he said if that continued, I would have to bring her in and he would wrap the other leg so that she would have to use the FHO leg to run. I told Ilsa (seriously-I know-crazy) and she's been doing much better. She has until the end of this month to prove to me that she will use that leg all the time or else she goes in for a wrap.
Telling you all this to say-they will touch down as they feel comfy-and each dog varies with that. Call the vet if you are concerned, just to check up on her progress. It never hurts for them to take a look or hear your worries. Also, I think the recovery took longer than I thought. She did the touching down so quickly that I expected the rest to roll right along, but it took her quite a while to be able to be proficient in using the leg for turns, etc. And keep an eye out for faking it!
