Over the weekend, we had a guest in our home. His name is Cooper and he is my sister-in-law’s miniature Dachshund. You might remember from other posts here that I have a dog, Charlie. And you might also remember that Charlie is a mix of Boxer and Greyhound. The thought of having two such similar and yet polar opposite dogs in my home made me smile. What can I say, I like Mutt and Jeff scenarios. I really was hoping that they would be a match made in heaven, albeit a doggy-tail-wagging one. Alas, as all veterans of the playground dynamics know, mere proximity alone is not all that is needed to create a meaningful and lasting relationship. Relationships take work.
