One of my borders was oxygen deprived at birth and has a touch of brain damage, He's still a lively, game little thing, a real have a go-er, but he's been a bit quiet since last night and a bit unsure on steps etc.
I dunno if he's just worn himself out (we did a good few miles yesterday and he was going full pelt with all the other dogs, or if he's hurt his back. He doesnt seem to know how to stop even when he's knackered.
I'm wondering if the deerhound's ran him over when I've not has my eye on them all. It happened to my bitch last year and she needed the vetm but her tail was all limp
