Was he checked for Lyme's? Lameness can occur if a dog tests positive for Lyme's disease. I'd have a 4d Snapp test done. They're not expensive.
She didnt brought it up.
He had blood tests not even one year ago and everything was fine.
I'll bring it up next time I speak to the vet.
I read symptoms of lyme's disease and apart from lameness, he dont have any of those (lost of appetitie, swelling,etc...)
But thanks, I'll bring it up next time I speak to the vet.
