Hey Britster,
Thanks for your reply, I really appreciate it!
Yes, Miloh turned 7 months yesterday. I agree, but felt bad as everyone moved their dogs to the big dog area. Phew, I'm glad I'm not at fault on this one! My boyfriend actually lost his patience and began to push the Jack Russell off Miloh once he began to get too aggressive. I try not to pick him up as much as possible, but that crazy dog continued to push his front paws down on Miloh's head.
I'm going to try to set up a play date with various dogs at my house, hopefully he'll get accustom.
