This is relevant to lots of small dogs today. Many are carried around and don’t get to be dogs and play with others. We have seen such a positive change with small dogs that have boarded with us. By allowing them to interact with all sizes of dogs, they are exposed to a varied pack as nature intended it.  They are no longer bound by the misconceptions or fears the owner may have.
