I have a full grown male Dogo Argentino. He is very strong and I can't find a good toy for him because he tears EVERYTHING up. I got him the strongest rope you could but at PetCo and he tore it up, I got him the Kong Ultra or whatever the extra strong kong ball is and he tore it up, I buy him giant knuckles and he literally tears them up. If you guys know any toy that you have had experience with that can withstand an extremely strong dog than please let me know. Thank you!
