Why is my dog acting this way?

the dog is protecting you. the dog is probably scared that your husband is going to hurt you or the dog. i suggest spending more time with your husband and your dog together. this is also still happening with my dog. right before my dad goes to bed, he goes to kiss my mom and then my dog jumps up on her lap and snarls and barks at my dad. they've been spending more time together and its not happening as much. hope i helped and goodluck<3
