[Mifune]

Hard to predict how an already established pet will react when a "playmate" comes to reside in the household as opposed to "visiting" ones.

In a Only Dog situation where we assumed he needed a little sister our male Cairn terrier, Bandit had a drastic personality change when he realized the New dog wasn't going away. Although in time he adjusted to having Roxie around something about his personality was never quite the same...they didn't fight but nor were they ever really close "friends".

Although we loved them both, until their dying days I know we deprived Bandit of being the sole object of our affection so in our case the new puppy had unfortunate ramifications.

Not advising "yes" or "No" just relating our experience with a very intellgent & sensitive pet who needed to be THE pet & would have been happier without a playmate.
