My puppy is a jerk!

Following this thread because Delilah's a bit of a jerk too. She likes to steal whatever Mia or Sophie has (food and toys) even if it's not something she wanted in the first place. Even "yucky" kale or lettuce that we give the bunny- Delilah hates it but she'll steal it from Sophie if she gets the opportunity. Right now I'm just trying to prevent her from having the opportunity to steal things.

One thing that's worked for me for giving Mia and Delilah treats and attention is saying "Mia's turn" and giving her a treat or a pet and then soon after saying "Delilah's turn" and giving her a treat or a pet. Delilah's learning that even if I do something nice for Mia it doesn't mean that I'm going to ignore her. At first I had to give them both a treat/attention at the same time and then I staggered it a bit, giving one a treat first and the other one immediately after and gradually increased the time in between (while saying whose turn it was). Delilah tried to steal Mia's treat a few times but I had her on a leash so I pulled her further away and had her sit and wait and then I rewarded her once she started focusing on me and stopped focusing on Mia. I don't know if this is a good solution but it's been working for me and now I'm able to train them together and bring them on hikes without Delilah trying to steal Mia's rewards.

We still have the stealing problem with toys though- things that are easier to take. Haha, the other day I was playing frisbee with my dad and the dogs were running back and forth trying to catch it and Mia caught it and Delilah wanted it so she yapped at her and Mia growled back and Delilah backed off and I was like, "Good for you, Mia, stick up for yourself." Mia usually lets Delilah take her stuff.

Lol I have a couple jerks too.

I supervise/manage a lot of it and my crew gets along pretty peacefully, but no doubt wouldn't if not managed. It's honestly just become second nature and I rarely think much about it unless needing to a address a new issue...

For addressing stealing with my guys, I teach meal locations and to settle in specific places. Normally the only time they have valuable stuff is under direct supervision (crated or in separate locations w/o access to each other if unsupervised). When it comes to chews, I send them to their spots (previously trained), hand them out, and watch. I give bonus regards, especially early on, for staying settled. If anyone even thinks about getting up to steal I calmly redirect them right back to their place and chew. Oh! With new dogs I often use ex-pens, tethers, and tab lines to help manage this.

If being a brat and trying to steal a found item from another dog, maybe a stick or something, I normally just call the offender. Reward for the recall. Then redirect them to their own similar item.

For your mealtime issue, maybe try covering her crate to block the visual of the other dogs? If that doesn't work, I would then move to feeding her is a different room entirely.

For waiting turns, I play the name game with multiple dogs and a multiple dog settle (eventually switching between who is working/getting attention).
