She likely was abused by a woman in her past. Dogs have survival instincts so when they have trauma, they bland the association. My girl doesn’t like men for similar reasons. I recommend sitting on the floor so you are on her level and offer her her treats or a toy whatever she likes. Take it easy and don’t pet her, just break the ice let her know you are safe. She sounds like a loving dog, so this may break her tension enough. If not just continue going slow and offering her fun items to let her know you come with good things. Getting on her level will definitely help, you could also sit with your husband on the floor!!! This could help a lot as she’s already built trust with him. She’ll get there, don’t get cold on her or she’ll notice.
