Thanks Rachel,

Yes, he is a good boy. When we go out for his pottie
trips, he looks longingly at the front sidewalk. He wants
to go for his walk. I really don't think I should stress the
knee at all until the Vet can check him out.My daughter
says "mom, if it was a popped kneecap, Bud would not
be able to walk at all". She's probably right, but how can
a goose egg sized lump appear on "that" leg overnight?
Well, Bud acts o.k. otherwise, so we'll just wait another
day & find out what the Vet thinks. Bud says to tell you
he's "keeping his tail up". Thanks for thinking of him. Liz.
