Dog is 10(ish), no health issues, fit and well (we thought) About an hour ago he came staggering in from the garden with his legs buckling under him and his head stiffly turned to the side. He looked a bit panicked and not with it. At first I thought he'd hurt his back but the look in his eyes made me think it was more neurological. After about 2 or 3 minutes he was back to normal although still seems slightly stuff/wobbly on his legs. Never seen him do anything like this before. Can anyone advise?
