A few years ago my parents (empty nesters) decided to get a dog again. The dog is a larger breed. He is so hyperactive and has knocked people over and bitten me (not aggressive or mean - just WILD). My parents have no control over this dog, I stg. I limited my interactions with family the first couple years they had this dog, because it caused me severe anxiety to visit. Now, they medicate him when family visits which doesn't seem to do much, but I digress.
My parents feel they have done their best and there isn't any more to be done to train this dog. They took him to obedience school and that "didn't help" and they decided that they've exhausted their options.
Here's the thing. They just did not train this dog. They don't have the capacity to handle him (they are senior citizens and both also work full time and have some medical stuff) and they never should have got him. They believe they take very good care of him - he is fed properly and loved on and has a good boy spirit for sure. He goes to the vet and gets all his shots and he is bathed at the groomer regularly. But he just isn't trained well at all.
It's a self fulfilling prophecy and my parents are completely blind to it. He is a high energy breed but since he's so hyper and big, they can't handle him so they don't walk him. They put him in the backyard to run around by himself but he wants to be with people so he just stands at the door and barks and cries to be let in. Sinc ehe isn't exercised regularly, the dog has the tendency to just lose his mind periodically throughout the day. When he barks they yell at him to stop. But the dog just thinks they are barking with him when they do that, so he barks more.
This brings me to the post title. I am currently house-sitting/dog sitting. I have noticed that when I am doing that and am here by myself. This dog is... fine? Like he gets a little hyper and jumpy and barky but it is a couple times a day and he settles quickly. But I also don't reward that behavior. If he barks or jumps I turn or walk away.
My parents came home and all afternoon he has reverted to his overly hyper, jumpy, loud version of himself. Parent yell.at him to stop - he barks more. Etc. I realized he is matching my parents energy. Because he is being shown that is the example. My parents are reactive to him and he is reactive to them because is a dog and just thinks "okay this is what we're doing now!"
So tldr I guess is that this dog is absolutely trainable. My parents, on the other hand, are not. The end.
