Well I called my vet this morrning due to sign Zeus has been showing he has been having a terrible time walking and getting up lately and it has seemed to get worse and worse at first i t was just in the morrning so we thought maybe his crate was getting to tight so know he doesn't sleep in it. But the stiffness in his hind legs seems to be getting worse every day. I Called the vet this morrning so we will be taking him in next monday unless it gets worse and he told me to bring him right in. So that has been my excitement lately that and family health problems
