I'm so sorry that Smokey has been having so much pain with his knee.
Althought I do know that a Luxating Patella never heals itself, some dogs
are able to get along without surgery for a long time & not show any bad
effects from it.

The surgery is expensive, as it is with hip displasia, but it can also work
wonders to end the pain altogether. Here's hoping Smokey can be helped
to keep on truckin for a long,long time yet.Prayers for Smokey & his loving
dad too.
