Introducing a new puppy to your pet family, when it already contains an older dog, can be a bit of a rocky road, especially if your older dog doesn't have the energy or the inclination to keep up with his little sibling. Sometimes pet owners misconstrue the interaction between their new puppy and their older dog, becoming alarmed when the older dog corrects the new puppy to set boundaries and enforce respect. If you reprimand your older dog because you misinterpret his behavior for being mean or jealous, when he is just teaching your new pup some manners, you can, in fact, create a problem, where the new puppy does not respect boundaries of other pets in the home. 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. 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.
