The little turtle chaser. Yes, my baby, Jackson, even though leashed saw a little turtle and tried to chase it. One tiny wrong move, tore his knee ligament. I took him to my regular vet thinking he had a splinter in his paw and she sent me back to the orthopedic specialist that performed Legg Perthes on his..other leg 4 years ago. A piece of cartilage had to be removed and the nylon for the ligament He had a rough night and is mainly sleeping today. He stays still and rests as long as I sit right beside him. I've been awake for about 32 hours now, but I'd have it no other way. He's my baby. I know it's been rough on him, however, I'd rather him not go through this again buy putting too much strain on his ..now healthy.. little right leg. He returns to the dr. in seven to ten days I'll ask about water therapy swimming as he did after the LP surgery..he hates water.. but it helped strengthen the muscles. My advice is, after the vet guesses a diagnosis, if they don't refer you to a specialist, ask them to. Whether bone, internal, etc.. They should see a specialist. Good luck with your baby. I'm watching over mine 24/7...
