Mateo has a story. Actually, we all have a story. However, Mateo is being up-front about his. He is not a fan of other dogs. He can wave from a distance, but up close meetings just don't work out as he plans. He will come with a great resource which can provide some training and skills called "GoodPup" and he pawmices to be your best friend ever...if you pawmice to keep the dates to just the two of you.
