I'm breeding my Jack Russel Terrier, and she currently lives with a highly aggressive Doberman. For the Pregnancy, about 1-2 before her due date, I'm moving her to another home up north to have the puppies so the doberman cannot harm them in anyway. (the doberman in the past has been HIGHLY aggressive with other dogs and puppies). After the two months when the puppies are old enough to have new homes, I would like to bring my JRT back to live with me and the Doberman, but I'm not sure if the doberman will let her back in. Because she has new smells and she was simply gone long enough for the doberman to fully take over the domain. I need advice on what to do..
