Cute!

I'm 99.9% sure he has no boxer in him, and only the Mastiff breeds that I listed. This is mainly because of his body structure as well as facial features. I'm 100% sure on French Mastiff, as he has the colour and the characteristic patch of white, and he also pretty damn sure he's crossed with bullmastiff.

I've done my fair share of research, so I'm pretty sure on my conclusion!

However, no matter what he is, he has the deepest, most special place in my heart.
