Sammy is not impressed, at first she would get up and walk away, but lately, she has started growling at Mack. Sammy's owner has taken a lot of time to ensure both dogs get lots of attention and Sammy does not seem to be jealous, as much as she seems to be in need of peace and quiet when she wants it. Before this escalates any further Sammy’s owner needs to teach her new puppy to respect her older dog.
Often, allowing an older dog to establish respect themselves can resolve the issue, however, if your older dog is unable to exert himself or the new puppy is particularly boisterous, you may need to step in and train your puppy appropriate behavior with your older dog. Often, draining your new pup's energy by providing lots of play and exercise can help to control his behavior around your senior dog. Limiting access between the dogs with crates or barriers can also help establish boundaries. You should not punish your puppy for exhibiting boisterous, playful behavior--this is natural for puppies and punishing natural behaviors will only confuse your new puppy and create anxiety. Instead, limiting, correcting and redirecting playful behavior around your older dog, to establish personal space, boundaries, and respect will be more effective and provide a peaceful, comfortable environment for both your old friend and your new one
