It could be a territorial thing as well, Tia may feel that your husband is invading HER space and HER Mommy. Just like a baby who doesn't want Mommy to leave his side, Tia may feel threatened by your husband a bit and just hasn't warmed up to him... yet. As said above, start with letting your husband giving Tia treats, and try to get him to spend as much time with Tia as possible (maybe without Sandy around), on walks, or let him rub or scratch Tia for a set amount of time each day. The more Tia gets used to your husband, the more she will be willingly to accept him. I think it just takes time!
