Also I have a shih-tzu named Piddle, and he is VERY hard to train!! Does anyone have any training methods?? I tell him to sit, and I gently push his bum to the floor then I give him a treat, then I stand him back up, and firmly say "sit!" and he just stares at me, I show him the treat and I say "sit!" and he just stares lol please help! ~Thanks~
