This morning Daisy attacked Lenny and there was blood droplets on the floor when I got there. This is the final straw. She has never showed aggression toward a person, (beside barking) but if she ever bites anyone it will be already too late.

Just now there was a noise outside and Daisy jumped up growling and Lenny jumped up in a defensive manner. Who knows? If I wasn’t in the room maybe Daisy would have attacked Lenny again just now.
