Gypsy's fate

As if I wasn't confused enough...

Yesterday, while playing, Gypsy bit Maddie on the face and bit her by the hair. Maddie says it goes something like this: She was on her knees and Gypsy was licking her in the face. Then she bit Madison in the face. When Madison yelled "No" and tried to get up, Gypsy bit and held onto her hair.

To put it lightly, Mike was not to thrilled to hear the news. Especially since, as he reminded me, Gypsy has jumped up and nipped at Kamryn's feet while I was carrying her. He has reached the end of his rope. I've asked him to talk to a friend of his who has rescued dogs and I intend to do the same. I don't know what to do about this.
