Picked this little guy up from the humane society a few weeks ago. The shelter listed him as mostly a Boxer mix. At first, I thought boxer and pit bull terrier, but after seeing his coat grow, I'm thinking Boxer/Lab. I'm not much of a dog person and know little about breeds so hoping some of you can take a better guess. He's really smart and picked up on crate training and basic commands in just a couple of days. I took various pics to aid in identification. He's about 4 months old in these pics. Weighs about 18-20lb. Let me know what you guys think.
