Out of curiosity, where do you work? If you can't be specific, perhaps just indicate the general setting. As much as I love dogs, when I think of the myriad of dog behaviors and the myriad of dog owners, the lawyer in me cringes as the thought of dogs in the average workplace. Unless there were some well understood rules and expectations, along with a clear understanding of the potential liabilities, I just think there's too much room for problems. The mere fact that your concerns were brushed off suggests to me that your workplace hasn't given it as much thought as necessary.
Live with intention. Walk to the edge. Listen hard. Practice wellness. Play with abandon. Laugh. Choose with no regret. Continue to learn. Appreciate your friends. Do what you love. Live as if this is all there is.
