I have a Jack Russell that is suddenly becoming aggressive towards a dalmatian that we have been taking care of. We have had the dalmatian and another Jack Russell for a year now. My Rosie has been biting the bag leg of the dalmatian. This morning (Monday, Aug 11) she did it again only this time the dalmatian attacked back and had Rosie by the front of the neck and actually shook her like a toy. Fortunately my son was home to help me break the grip the dalmatian had on Rosie or she may have broken her neck. What would be causing this sudden aggression?
