My schnauzer is not interested in a puppy we are fostering possibly adopting which is 11 weeks old, lab retriever mix. We got the puppy sat. nite and it keeps jumping and nipping my schnauzer causing my dog to have no interest. He does not even try to put the puppy in its place when it tries to nip him. The puppy is in a crate or on a leash to keep it under control. Does anyone have any knowledge on how to introduce a puppy and an older dog. Any help would be appreciated.
