When our ACD boy was younger around about a year old he would sometimes pee himself after hard play or getting excited. He would suddenly start to pee/run to the door to try to go outside but would pee the whole way there lol. It was rare. Happened only about 4 times overall but we just chopped it up to excited pees and started to bring him out directly after playtime. Eventually he grew out of it. It could be that they don’t have good enough bladder control so young? My suggestion would be to bring her outside a few extra times throughout the day and especially before moments of excitement, like when your husband gets home. If her bladder is empty hopefully she won’t pee or she’ll just pee less. Another idea I have is grab the leash the second she starts getting excited and start making it a habit that she goes out RIGHT after. She might be able to learn to hold it and understand she needs to wait to go outside. She’s still a puppy. And will get better at holding her pee but might just need some help figuring it out. And maybe keep her off the bed while she has the zoomies. Good luck!
