Lag Spike is really one of a kind - he is a mini fox terrier cross (probably a Jack Russel but he was a rescue dog, so we'll never know for sure). Since we've had him he does this sitting thing. It's like he goes to beg, but when he sits on his hind legs, they splay out at a strange angle. He can hold the position for a good 5 minutes too. Lately he's been doing it more and more - mostly because he knows that it freaks me out and I will call him over.
When he first arrived, we had a vet check him out and the vet said that he had a couple of medical issues (tumor on his eyelid, heart murmur, stiffness in his back legs which may lead to arthritis), but there wasn't anything he could see that was immediately wrong with him. We are off to a new vet on 8 Sept, but I would love to have other opinions about this behaviour too.
Here's a (bad) pic of him sitting on his hind legs.
Thanks,
Megs
