Hi and welcome to Yorkie Talk!!
You do need to realize that dogs are pack animals and they love having other dogs in their family. They learn things from other dogs that they cannot get from people!!
There is an alpha dog in the pack and you need to let them figure out who that is while always realizing that you are the ultimate alpha" and you control everyone in the Pack, including the alpha so if you don't tolerate aggression then even the alpha will not be allowed to use it. |
