He goes into beast mode

Just like your roommate who counted out your M&Ms from the communal bag, dogs place a high emphasis on fairness. “Dogs get mad if they have been treated unfairly, and may act instantaneously with bursts of rage,” Olshavsky says. What this looks like may be different for each dog but you’ll know it when you see it. The solution is simple: more exercise. “Dogs need to get that energy out in some way and a daily walk is the perfect way to do it,” she says.
She tells you – loudly

Think dogs don’t have a voice? Then you’ve never seen a puppy kennelled. They may not be able to use words but they can vocalise their displeasure. Whimpering is the canine version of whining, Olshavsky says, and it’s every bit as grating as the human kind. To cut down on whining, set aside a few minutes each day just to play and work on tricks, she says. Give her your attention when she’s not whining and she’ll learn that whimpering/whining doesn’t work.

He groans like an old man with kids on his lawn

Yes, some dogs actually groan in frustration when they don’t get their way, Olshavsky says. “Some dogs are quick to do this, while others reserve it for times when they are especially upset,” she explains. A major cause of groaning? Getting locked in their crate, outside, or somewhere else far away from their beloved humans. It’s fine to banish your dog during certain times or from certain areas but make sure you’re giving him plenty of regular time with you every day.
