Let me start by saying my dog is petrified of the vets. So much so that we have to sedate him. He's a chihuahua cross Yorkshire terrier so small breed and only goes to the vets when absolutely necessary due to the pressure it puts on him.
A couple of days ago he was running round the corner and yelped. I've noticed that he limp on his back right leg has got worse over the past couple of days and today he's just been sat in the same position all day. If I call him to go out he just looks at me. On the occasions that I've picked him up to go outside he's has walked on it fine to have a wee and poo etc.
I've had a good look at his leg and can't see any obviously reason - like a foreign object being stuck etc and likewise he lets me touch it, move it round etc.
My DH thinks he's sprained it. I'm worried about him and don't know whether to take him to the vets - remember we are told to only take him if necessary. WWYD?
