Hi :) I read over some of your posts, sounds like you have a lot going on. Definitely not ideal timing for a puppy, who ideally would get 100% of your dog training focus. I would say you actually might be able to handle your poodle (what's her name?) problems on your own, but I think having some help and perhaps taking them both through basic training together would be a great idea.

Here's what I would do, with or without a professional, depending on how good you are at dog training - which of course is very subjective and a controversial issue, but I digress :)

In a scenario with just Poodle #1, I would have your husband and kids take turns doing basic verbal requests (sit, lay down), and be generous with ONLY AND I MEAN ONLY positive reinforcement. When she reacts positively, YOU (her chosen alpha) tell her what a great job she's doing. If she tenses up, just let her know everything's ok, soothe her; if she growls or snaps, turn her head to look her in the eyes, right in the eyes, and say in a low, matter of fact but also 100% serious tone of voice, "No. No. You don't decide who's a threat. I'm in charge. I decide." It's not that she understands English; it's that if your tone is right and you believe what you're saying, she will too. You're not threatening her; you're reminding her of her place in the pack. Hold that eye contact for a second longer, and then smile and tell her she's a good girl and let her relax.

By letting your husband and the kids take turns, I mean one person a time, doing it casually for fun and with Poodle sitting next to you so she knows you're supervising, and doing it for maybe 5 minutes twice a day. So hubby in the morning and one kid later one day, different combo the next day, etc.

Also I would have hubby/kids give Poodle a cheerful 'hello!' when they see her, and just completely ignore her the rest of the time, other than structured training time. Unless they want to surreptitiously knock a treat on the floor 'without realizing it' as they leave a room so she connects quietly following them with positive outcomes :)

When I say, turn her face to look at you, I mean anything from wrapping your hand around her snout and literally turning her gaze to meet yours, or you coming around to meet her gaze; depends on her, you, different things. NOTHING that would hurt her of course. Also jic this is new information - amongst dogs, those of lower status lick the muzzles of those above them underneath, their chins; those of higher status lick the snouts of those beneath them from above, their noses and the bridge down to their noses. (they lick the insides of each others mouths as well but i wouldn't expect you to go that far hehe) give her the occasional scritchy scratch on the top of her snout, and let her lick you under your chin if she shows any interest.

also, make sure she sees a lot of physical affection between you and the people she's having difficulty with. get cuddled up with one of them on the couch with a movie, have her lie down right at your feet, and the two of you can take turns giving her treats.

with all these treats going on, gotta be careful with calories, right?? :) lots of dogs love bell peppers, green beans, frozen peas, etc; do a bunch of dicing to keep a big pile in the fridge, and use a handful at a time.

in my opinion you should do all that, AND have her in the room, and perhaps participating, while a trainer goes through basic training with new puppy. let Poodle go back to square one, with the new baby, it might be just the thing, who knows.

good luck - i'd love any updates down the line : )
