Well, here is my thought process (paranoid?) If a Yorkie can just jump off a couch and ahve to have its spine or neck fused back together and end up in a doggie wheelchair, well what if Pixie (husband named her not me
) steps (accidentally) on Sophie's back she could end up out of commision. Pixie is not at all careful about where she steps or walks. Poor Sophie normally cowers down on the ground if Pixie is out around her. I think it would be great if they could run and play, but I am so stressed out when they are together, I am just constanly worrying.
