Bella is a roughly 18 month old Boerbel Mastiff/Great Dane mix. She usually has a very delightful and playful temperament but just recently she without unprovocation, attacked my older Mastiff who is smaller than her. We are rehoming her because previously before when she was going into her first heat, she did this to my male Great Dane, also without unprovocation and thought it due to be to hormones. It is for this reason we want her to be in a home where she is the only dog and there is no worry. She loves giving kisses, loves all her toys and loves cuddling in bed.
