Not sure what to do about this situation/behavior
Okay so, I have 2 yr old heeler. She of course acts like a 2 year old heeler and she is perfect and amazing. BUT the behavior with me vs my dad is insanely different.
When he is home she will just stand and bark and bark and bark at him, she doesn't listen to him and I often have to go and ask her to stop and she will stop until I leave the room again. She completely forgets any rules, no counters etc. She will "bite" him (not exactly a bite but a good nip.)
She is my dog and from a puppy she was taught any type of mouthing skin is a no no. And she listens perfectly when it is me or my bf. She doesn't even attempt to mouth.
Even when my dad tries to correct (hardly ever) her on any of the bad behavior she completely ignores him. It seems to be only getting worse.
She barks when people leave the house, but she goes crazy when he does. I crate her when I'm around and he is leaving and she just barks a bit, after he is left I let her out. But again he refuses to do so.
No matter what I tell him to do he ignores it, so is there anything I can do that doesn't involve him helping? Also does anyone know why/ have an idea why she does this with only him?
It's driving me insane.
We are here for about a year longer until we buy a house.
I'm worried about her behavior as she has already become more shy of people when we are out, that's only been happening for about 5 months. Before she loved people.
With the 'biting' becoming more of a thing I'm worried this will turn into something bad if all this continues.
