Little teenage casanova

Boris has 3 girlfriends (that I know of) in the neighborhood.
There is Lucy, the beagle next door, who he plays with often.
There is Lacy, a lab mix of the same age who lives 2 doors down.
And there is Doogie, a furry little mutt who we see on walks. She is a little older, so we call her the "cougar".

Boris is now acting like a teenager when we go out in front of the house. He is always looking for one of his friends and taking any opportunity to run 2 doors down to find Lacy. In fact, on at least 2 occasions, he ran over to her house and barked at the front door for them to let him in. Another 2 times, he ran down there and just ran into the open front door. Little devil!
