Hello, I don't post very often on these boards but I'm a little concerned and thought maybe all you good people might have some advice for me. My daughter works for a lady who breeds Bullmastiffs and Bordeauxs. Not a puppy mill. Very nice farm. Anyhow, her sister also breeds but is not as ethical as she is. And the sister's husband is a jerk. A couple of months ago they gave my daughter a 6 year old Bordeaux (retired breeder) that he apparently beat and kicked regularly. She was so sweet and lovable. We were so happy to get her. They thought she was bred. But she wasn't and bled for a week (?) Now suddenly she is acting aggressive. She barks at my husband and 2 younger kids. This morning she lunged at my 10yos and barked and growled. One of my other dogs got between them and she stopped. He was just sitting watching tv. She has been banished to the yard because I can't risk my kids. She is very attached to me and never leaves my side otherwise. I just don't know what to do. I'm very upset. Any ideas? Thanks in advance.
