First of all I want to truly thank everyone for your help and advice. I can see you really understand how I feel.Well I guess I made alot of mistakes, I wish I could do it over.. I have just been so stressed i should have realized when Nieko kept taking everything I gave the pig (toys,blankets etc..) When we got out little Maltese, Bella nieko loved her right away no problem. Obviously the pig will remain with my sons. We do live in the same house, they have thier ownnplace upstairs..when I say I try to tell my daughter tomput him in his place,I mean just to let him know he can not play rough with her, and she shouldnnot let him intimidate her. I would never hurt Nieko, and I am not strong enough. When I say throwing him on his back it meand holding him down until he calms down, and yes with some force. He is over 100 lbs. You never know how you will react until a situation arises. Its my fault I havent been consistant with him for a while, hes been getting away with a lot. But now my daughter is scared and I hope he wont pick that up. I have to say he is a completely differnt dog since the piglet is upstairs. I love Nieko dearly he is my best pal and my shadow, just the thought that I would ever have to give him up makes me sick!
