I don't think it is rude to let the dogs eat the left overs over this human that is being rude and mean and taking things for granted.

He is a renter of a house hold that has other people that live there.

I agree there should be boundaries but if there are common areas like the living room- then well, that is just that- common areas.

(((I hope things get better)))

I do hope that this guy, is just blowing off steam, perhaps things are bothering him and misdirection to you perhaps? I don't know, but a suggestion of another angle as well.
