What would be less stressful for my dogs?
So I have two dogs, one border collie mix and one Chihuahua. I still live at home with my mom, step dad, and step sister (who has young daughters that come to visit every so often). For the next several months, my brother's family is moving in with us. A 1 year old, a 4 year old, a preteen, two teenagers, and his wife. (By the way, we only have one shower in this house.) My Chihuahua doesn't like new people (especially children) and he'll hide in his kennel the whole time, or my room. My border collie mix doesn't mind new people, but when there are kids involved that are loud and want to give her more attention than she wants, then she will want to hide away in my room where it's quiet. I myself am like my dogs and like the quiet, so during these months I will be back and forth between my boyfriend's house and my aunt's house. One week at my boyfriend's and then one week at my aunt's back and forth until my brother's family is moved out. I'm trying to figure out if it would be more stressful to leave my dogs at our house where they are comfortable with the house, just not necessarily with the people. Or would it be more stressful to bring them back and forth with me between two houses I will be spending time at during these few months? My border collie mix is a bit of a nervous dog, and she gets uncomfortable in new houses (especially if there isn't carpeting. She will cling to carpet in a new place like it's an island and everywhere else is lava). And my Chihuahua will probably only be uncomfortable with my boyfriend's roommates. But two more concerns of mine are if they go with me where I stay, they will be left on their own while everyone is at work. At my mom's house there are people around during the day. The other concern I have is I had a dog go missing (and never found) one time when a family member left our front door open when they were visiting, and I'm afraid of that happening again.
please give me some advice
