My husband and I recently adopted a 2 year old adorable mastiff mix (we think he's mixed with Plott hound?).
When we were at the shelter, everyone worked there called him a monster, and said he was returned 3 times because he was too crazy. Everyone knew who he was and kept saying the crazy dog, poor guy! Since he was so adorable, we decided to look at him anyways and fell in love! He was sweet and not too crazy (of course he was acting different there) and we clicked so we knew he was the dog we were looking for!
We brought him home and he was strangely calm. Then a few days later, his crazy side came out, what everyone was talking about.
99% of the time, he is the sweetest, loving dog and is perfect! He listens, is very smart and a quick learner. I've taught him so many things already and it didn't take very long!
The other 1%, he goes nuts! He tries to play with us but doesn't understand how, and plays way too rough! He'll demand bark to play, bite our clothes and arms (really hard too-he's drawn blood on my dad), and jump on us constantly. We've tried a whistle, ignoring him or walking away, time out, distracting with other toys or an action such as sitting, even firmly saying no. He looks scary like he's being aggressive when he barks, but then he's sticking his butt up and wagging his tail, like he's trying to play and will only stop for a few seconds when we say, do you want to go in time out?
People keep telling us, he just has a lot of energy and needs to run. However, even after two hours of running, or a long walk, it's almost worse, like he's too wound up. We try to settle him down with mental stimulation toys (treat dispensing ones or something safe he can chew on).
He sometimes demand barks when we're eating like he's saying "give it to me!".
It's almost like he was never taught not to jump, bite, or play correctly or the many previous owners brushed it off and got sick of it so they returned him with the bad manners still there. He was also probably never taught as a puppy.
Also, at the dog park, he'll jump on people but will mostly be sweet (not bite or bark). With other dogs, he doesn't understand how to play with them but will gladly sniff them and try to play. Other dogs realize how awkward he is and walk away, even when he wants to play.
Watching his behavior with other dogs makes me think it's reversed. He plays with us like we're dogs but with dogs he's shy and awkward.
I remember the shelter telling us he is bad with kids only because he jumps and is 80lbs and is a tall lanky guy. Everytime he sees a kid at the dog park, he runs up to them excitedly and jumps on them and licks them.
We want to get him into training and maybe some doggy day care for socialization. But I'm not sure how to get rid of his bad habits of the jumping, hard biting, and barking at us. I feel he's slowly getting better but it's 2 steps forward, 1 step back kind of thing.
We're never giving him back but we get so annoyed with his bad habits and need help. Any advice on how to stop these habits? Are we not consistent enough?
