Hasan makes me too angry to even begin to be a thread regular but that dog is obviously a chow mix.
Chow chows were and are bred primarily for guarding. Give them a perimeter, a fenceline and they will guard it with their life. They will spend hours patrolling, walking the fenceline and staring at passersby.
All the dog wants to do is what it was bred to do.
I am not one that will spread the bullshit of "chows are aggressive monsters" but he's lucky she's got a submissive disposition.
If only her mauling him wouldn't result in her immediately getting Ole yellered, a rainbow outcome is she gets removed bjt those breeds also tend tk struggle with the stress of rehoming especially after being abused or stressed.
Whatever. Sad case, Hasan is an insect and Kaya is a very good girl.
