I've got a 15 mth old staffie/sharpay cross bitch. I've had her for about 6 months now, she was an abandoned dog found by DS and taken in by us. Unfortunately things really aren't working out. Although she's mostly sweet natured she has snapped at DD (4) several times and last weekend snapped at her face twice, not breaking the skin, but leaving marks. DD was not doing anything inappropriate or aggressive towards the dog at the time. As a result of this I really don't think I can keep her anymore, I'm scared she'll hurt DD. I don't know what to do.
