I'm calling the vet for Lucas tomorrow morning when they open, but I'm really worried. It was only Saturday that he did the wobbly thing and almost fell with his right foot and now today he showed a new problem with his right foot. He was walking down the hallway and he dragged the top of his right foot and stepped on the top once. He didn't even seem to notice he was stepping on the top of his foot instead of the bottom. It was only once, but that really worries me! It's obviously his right leg that is much worse, he's shown no problems like these with his left foot but his left leg he limps on also. I'm just really worried at how fast it's getting worse! And he's only 7 years old too!
