You know now that you mention it, I wonder..... Bailey was diagnosed a level 1 LP at her very first puppy visit. She had no troubles at all until she was spayed at 7 mos - then she started limping. I never thought to connect the LP troubles with being tied down at surgery?? But I bet that was it! Makes sense!
Anyhow, when Bailey limped - I took her back to the vet - concerned that it might have been the deteriorating hip bone disease (the name escapes me right now). I was somewhat relieved that it was "only" LP. The doc confirmed that it was still only a level 1 - but said that surgery might help and that I should talk to an ortho.
It was Nov. at the time and I decided to put it off until after the holidays. Oddly, Bailey never limped after the vet visit. So, the short answer is that yes, she got over it.
Bailey is now 2.5 years old and no problems!
