our trainer and our breeder both told us, a new dog into an environment requires skill and patience. Remember dogs have a pack mentality. That means their is a hiearchy in the pack. Presumably it is your husband, you, they the yorkie and then the Malitpoo (likely she was there first) and then the bischon. Now everyone is trying to rearrange the hierarcy.. and you must let them do it themselves. do not intervene. Even touching or punishing one or the other shows preference from your for hte hierarcy.
The best way to introduce a dog into a new environment is to have them meet in a neutral territory first several times. then bring them into the home together. If you watch carefully, you'll also notice even when they are coming in and out of the house, or being walked, there is always one who has to be up front. "top dog" Leader of the pack. They all work it out just fine. don't get upset if the growl at each other either.
All good blessings.
