Lisa K., I'm so glad you found Winston so quickly. What a smart dog to come to the front door! Piccolo some how got out of our backyard, when she was a puppy. I thought I was going to have heart failure. But, she was just like your Winston, she was sitting by the back gate, by our deck, waiting to get back inside. Glad our furbabies are not runners!
Deanne, you asked about Luxating Pattelas. Lisa K. was right about the knee. What I have found out is it is something like a slipped kneecap for a human. I'm glad your vet checked your puppy's knees. My vet also moved Piccolo's kneecap around and asked me to feel a certain clicking movement, which I guess means she has LP in that leg. He also gave her an x-ray, which did not show up the LP, but showed no broken bones. At least she does not have to have surgery at this time. Anyway, it sounds like your puppy has great knees!
Again, thanks everyone for your concern.
Lisa and Piccolo
