Believe it or not, I actually thought about giving my Rottie some sus 250. Once a week for 8 weeks. But, he's my buddy and I love him so I dont want to hurt him (not knowing the sides on a dog) so it will only stay an idea. ***BUT, in the dog fighting underground there has got to be someone who does this.....anybody ever heard of it actually being done?? Only curiousity guys.
