More: Leo is endlessly charming and interesting. He has these passionate obsessions such as playing catch or sniffing around new territories on our hikes together. But he can also be so tender and loving when we’re just hanging out at home. I love watching his mind and personality develop over the years. I swear he just keeps getting smarter and smarter and more nuanced in how he communicates. My next goal with Leo is to take him in a road trip so he can see more of the US.
