I have two 8-month old chi's (Ponco & Sasha). I recently purchased a 2-month old Pug puppy (Milo). Poncho & Sasha have been terrible since I've brought him home. They refuse to interact w/him or even play with him. Milo is so playful and will leap and jump and bark at them (playfully), and my other two will either run away or bark or bare teeth at him. Milo stands his ground very well and doesn't seem the bit intimated by them, but I'm worried about how they will be when I return back to work. I've taken off of work for a week, just so I could introduce them properly. Poncho and Sasha have now started to make boo-boo's all over the house, something they never did before. I think Sasha is far worse than Poncho. She seems as if she'll possibly really hurt him, if I didn't supervise all they're time together. Its only been 2 days ... any suggestions?
