When I brought Louie home, I had already made him a toy box. I put all of his toys in there, and if he got a hold of something that didn't belong to him, I'd redirect him to his toy box. It worked great for me. He learned quickly what was, and wasn't his. That, plus crate training for housebreaking. It just about drove me to the brink of insanity, but it sure was nice when he didn't "go pee pee in the house" anymore. That's what I used to say to him. YOU GO PEE PEE OUTSIDE!!! PEE PEE OUTSIDE!!! My friend thought it was funny... she said "Jaime, when he's a big ol' boxer and you're still saying "pee pee and poo poo" you're gonna look funny"... she uses "take a break" and it works well for her dogs... but I'll stick to my pee pee phrase it works for me.
Good luck in finding your baby...
