Send one somewhere else? It's quite common around here in sport circles.
For days 1-10 she is allowed out with the boys with her diaper on, crated when we are not there. On days 10-14 she is kept exclusively separated from them, on different floors of the house behind multiple doors when we are gone and EVERYONE is crated when we are not home. After day 14, and after whining and pacing in the boys stops, she will be allowed around them with her diaper on again HIGHLY supervised for one week, and then back to normal.
this is why I will never have intact females. Our house is very small (500 SQFT if its lucky) I already have to seperate Lincoln and Josefina because she has arthritis and he is super rough on her and hurts her , I couldnt imagine having to do a three way separation ... yikes! No thanks. I would let them go through one heat and that's it, my boys are always neutered after their growth plates are confirmed closed. I am never going to show conformation, or breed, so to me there is no need to keep them intact.
FYI Sawyer is an ACD, so he will probably be an ass LOL.
He's usually good at NOT being an ass!
I am keeping him intact unless given a medical reason to do otherwise, but ideally she won't be spayed until at least 18 months. But yeah she for sure will be spayed.
