My dog is vaccinated with 5 course post exposure rabies vaccine after 2month of exposure (non bite non scratch most probably just given him for added safety). His last vaccine was on 5th April evening 6pm after 36 hrs aprx on Sunday morning he was facing problem to lift up his back from sleeping position. He took almost 1min aprx to lift up his back. This problem continued for 4hrs aprx. But 1thing I must say that he was playful jumping on sofa once he lift up his body. His hind leg was more slippery although he has this problem since his childhood but now observable more after 5course vaccination. I gave him rantac for gas as he has constipation problem since 1weeks and also massage his hip and hind legs with arnica gel a homeopathy medicine for mussle trauma. He don't have prblem to lift up his hip right now but hind leg slips almost everytime .
