Oh Andrea I'm so sorry you're going through this with Bentley. You haven't had him too long, did he start this behaviour right away? I don't have any experience with aggressive dogs, but his behaviour sounds to me like he's trying to show he's the boss, or he's trying to be dominate, since he's ignoring you when you give him a command, and he's snapping at you when you try to correct him. I would be very careful with your daughter and not leave her alone with Bentley until you know for sure he can be trusted. It seems you and your boyfriend are doing the right thing by disciplining him, and ignoring his behaviour. A professional trainer would be able to give you better advice and training as how to get him out of this behaviour. It's hard to know if he did this before as he is a rescue, and he's two years old. You may never know his complete past history, and there's always the chance that the people who owned him before aren't always 100% truthful about the behaviour, but I can't see a foster doing this, because they are just a temporary home and the goal is to find a new and permanent home and one that is appropriate for the temperament of the dog. They usually list the traits of the dog such as if they are aggressive, whether they tolerate other dogs, or just a male or a female, or if they should be an only dog, they usually say whether they like cats, or children, and if they have a bite history. I agree with you that he needs some professional training and hopefully they can give you some direction on how to correct these behaviours, because obviously snapping, biting and especially snapping at your daughter are not acceptable. I don't know about the cat either, maybe they just have to get used to each other, I'm not sure how you would stop Bentley from attacking your cat, hopefully another member with experience with this will come along soon and be able to give you some advice. I have my two guys and they do chase my cat which we had for a year before the dogs came along. They will chase her, but have never tried to attack or bite her, they want to play with Meeko, but she doesn't want to have anything to do with them, she runs away and heads for higher ground. Lol. She will wait until night time when they are crated, and then lay on top of the crates and sleep there, or she lays on the floor right beside their crates, and when they are getting fed, she will wait until they are done and then lick their bowls. They won't play together, but they do tolerate each other and don't hurt each other. I hope you are able to find a solution to Bentleys behaviour and his aggressiveness. Please keep us posted.
