Apologies but I'm so very worried - our Connie will be 21 this June and up until a few weeks ago he was doing just fine. We've had him since he was 8, he's not been worked into the ground, mostly used for hacking. Never had any issues. One day he seemed to be struggling a little with his front right and having difficulty turning, so we rested him...next thing, he literally does not want to walk. We've tried to walk him out today but he is clearly not comfortable and looks incredibly stiff. I'm getting the vet out tomorrow but I'm shocked that he could deteriorate so quickly. It looks like it could be severe arthritis but can the onset be so sudden? I am so upset and worried, I'm thinking the unthinkable...but I just don't have any experience of this sort of thing. Can anyone help?
