I will try that then mate, my last dog had problems and it stopped him chasing rabbits. His jumping went all to shit aswell, he would be lay out in his run and suddenly yelp out and run into his kennel.
It took me ages to find the issue as they didn't swell. I thought he had a brain problem. The vet practically laughed at me when I said what was going on. He wasn't laughing when he touched one of them and 75lbs of lurcher almost snapped his face off lol.
180 notes the lastime the very same vets done them for me. Shows how much stuffs gone up lol
