Hi everyone this is my first post. I have two furbabies Sunday who is 7 and my newest addition Stitch who is almost 8 months. Sunday loves her daily walks so we started Stitch as soon as he could keep up. Stitch is starting to bark at other dogs and pulls towards them. I have him on a harness but he goes wild. It just started and I'm not sure what to do to correct him. Any suggestions?
