Hi, my dog whines when he lands on a hard enough surface.He was fine yesterday but all of a sudden hes not wanting to move alot now.Usually, in the morning he jumps up on my bed for a little bit but today he didnt so I helped him up.But immediately hes jumped down and squealed and the same for going down the steps to let him out to pee.I thought his legs might of gotten hurt but I checked all his paws and they were fine.Hes not walking as much as he did now and just lays in his cage and is hesitant to move.
