she's 14 and has had stick back legs for a year or so and somtimes loses her balance or slips on the wooden floor. Tonight though she is worse than I've ever seen her. Walking really slowly and staggering a lot. She hasn't eaten any dinner and has only drunk a little water and milk. She is walking her usual circuits out the conservstory, round the garden and back in the back door. I presume if she was in pain she would just lie down and whimper?
When should I call the vet out? I know I'll have to do it one day - but when is enough enough?
