Maizy and Lyla

We have a fuzzy little Golden Retriever puppy named Maizy(Who Lyla calls Mimi). Maizy loves Lyla and Lyla loves Maizy but they can’t seem to play together. Maizy loves to bite and play fight, but inherently seems to know not to do that to Lyla—still Maizy gets up in her face and can’t seem to leave Lyla alone. Lyla, on the other hand, gets all excited to see Maizy and yells and waves her hands, which just gets Maizy more excited. I’m sure they’ll end up buddies, but it’s a difficult relationship. Lyla’s favorite dog is our decrepit old dog Butters (who she calls ba-ba), for reasons I cannot really figure out.
