I just wanted to share this photo, I thought was cute. And ask, we have 2 doxies, Heinz is 6 years old and Ressi is going to be 1 in Feb., Ressi is very mean to Heinz, she runs into him making a thud sound knocking him down, is very selfish with all the dog toys, jumps on him, and is very jealous, we make sure we share our love not to treat one better than the other. You can tell Heinz is afraid of her. What can we do to help. We tell her no, try using a squirt bottle of water and it does not seem to work? Any suggestions?
