My friend says she has a violent dog who tried to eat their cat and will attack or bite literally everyone except for the dad (it's a dad and his two young adults children). They tried to get professional intervention but it didn't work. They can't re-home the dog because it has a bite record. They don't want to euthanize him.
Since nobody else can safely interact with the dog, the dog is kept in a crate whenever the dad is at work and also when dinner is prepared and eaten. Which is like 630am-5pm and 630-9pm. I can empathize with the situation of keeping the family safe but it does seem like a little much even though the crate is comfortable with food, water, and toys. Does anyone have any advice I can send over to my friend?
