when i was in undergrad i wanted to take my dog with me (it was allowed at the school). But whenever I would leave to go to class he would bark up a storm and it was ridiculous because like everyone on my dorm floor heard it. I got one of those shock collars.. thinking it would be ok and workk but I WAS SO WRONG. first of all, even on teh lowest setting.. the little 7 pound dog would scream in pain and because he screamed the collar shocked him again & again & again.. eventually he just collapsed on the floor. i tried to take the collar off but at that moment he barked with happiness and because i was touching the collar..
I got shocked. It was horrifying, because if it hurt ME at like 105 pounds, i couldnt eve fathom how much it hurt for his little 7 pound body

I really cant believe they actually still sell those things)
anyway, back on topic. whenever pebbles does something I odnt like i get the water gun (its this little tiny kiddie one) and shoot 2 sprays at her, all the while making sure she didnt see where the water was coming from. im trying to trick her into thinking that even if i am gone she will still get punished by some invisble force. lol she still doesnt realize its the water gun
