We have three dogs, the most recent is my avatar. She is what I think is a crossbreed between a schnauzer and a cocker spaniel. When my fiancee was diagnosed with cancer the dog, Bella, stayed in the home with her when I was away on business. This carried on for about a year, my fiancee is in remission now and we just had a baby daughter. \n\nBella has always been jealous of any attention the other dogs get. Since she is no out of the house and the baby is a new arrival I am scared that she might get aggressive with the baby. \n\nHow do I prevent this from happening?
