Our one year poodle x wheaten terrier is refusing to walk this evening. She's normally the happiest liveliest little dog. Went for a 16km hike with me yesterday no bother. Was perfect this morning and then this evening is refusing to walk and biting at her right hind leg when she tries to walk. We took her to the on call vet. She's not sure what's wrong. No obvious trauma. No clinical dislocation. No fever. Seems bright in herself. Just won't walk. She was given anti inflammatory injection and opiod tonight and if no better going back for GA and Xray tomorrow.
Any one any ideas?
