Good morning everyone, My girl has in the past (at least five years) had TPLO on both back legs and without any problems until last week when i noticed she was tip toeing on one of her back legs.  Is it possible something could have gone wrong or am i worrying about nothing?

It's important to get it checked. It could be something totally unrelated or the plate could have moved...

We had a good feel around it today and nothing seems to be causing pain around the knee joint but it seems a bit painful lower down at the back...OH thinks it might be Achilles tendon problem ?  problem is we are putting her in kennels tomorrow for three days so unable to get her to the vets until next week.  I just hope she'll be ok. Might ring the vets today to see if I can get her in tomorrow before we go.
