Thankyou for all of the well wishes everyone .

Phred, that what i was thinking at first but now when i look at him run it does not seem to be the kneecap popping out more of a stiffness in the joint.

Smoke's left hind Knee Cap is "loose" and slips out of it's proper
position - which sometimes causes quite a bit of pain when
it "goes out"!
Poor Smokey, it is a problem that is coming out quite a bit these days unfortunatly. I see it ALOT, poor dogs.

My Mums little Jack Russell Terror mix has slight Luxating Patellas but the Vet who checked her out said it was not serious enough for SirJury, she gets around ok but has the little terrier hop when she runs (Which is not all that often ).

Nicole, i too have heard GREAT things about the Weribee Vet hospital, i am hoping to get Elvis into there but may have another local Vet look at him first.

chocolatepuppy, How is Lacey doing? I thought of Lacey when i saw Elvis limping again . {{Hugs for Lacey}}

Once again thanks everyone, i will update soon.
