I have a 5 year old chiweenie and he was fine this morning but the afternoon when we came home he was acting weird and when I picked him up I notice his right hind side muscles were spasming and when I touched his left hind side he whimpered. He wouldn't go up stairs or jump on to the couch and when I put him on th enough he just laid there and then when my husband went to bed he normally follows but he just laid there I ended up carrying him upstairs to put in the bed and I am trying to figure out what is going on
