Just taken mine to emergency vet because she came in from the garden with her leg held right up couldnt put it down. Massaged it and gave it a good inspection, after 45 mins still not putting weight on and wouldnt eat a titbit(then its serious) thought she might have done her cruxiate ligament. Got to the vets, lifted her out of the car whereupon she walked on all four legs into the vets albeit lame. Anyway vet couldnt find anything wrong, bill for emergency visit £245 !!!!!. Ive told dog shes not getting any pocket money this week. Felt embarrassed as vet has 20 min drive to get to the surgery
