Last night we noticed that Rusty suddenly decided he didn't want to walk, could, but wouldn't unless he really had too. He has been refusing his food for about 3 days now but figured he just being picky, he done that before. He will eat if I give him soft food. Also noticed his tummy was really hard. And he hasn't been pooping. Took Rusty to the vet. He has 2 slipped disks one is pushing up into his spine right where his tummy is hard. He got a couple shots and some meds. They said he should be fine and be back to normal real soon and his body will learn to get used to it. I should only worry if his back goes out and he cant walk at all. He has to take it easy now. Please say a prayer for my little guy.
