I have a 5 month old golden retreiver/mini poodle mix. My friend has a 6 month old chihauaua (sorry don't know how to spell it). Her dog constantly barks and bites my dog. Now my calm, happy pup starts barking at her dog or comes running next to me when the chihauaua comes near him. My friend tries to stop her dog but its not working. Can you make 2 dogs get along?
