This is my best friend Dexter

We got him 7 and half years ago when he was just two months old. He was found in a dumpster by a family friend with no identification, chips, or vaccinations. For the past seven years we’ve been unable to figure out what he is. We know he’s a mutt, but honestly he looks like an entire different species

He’s very photogenic as you can tell.

But if you have any guesses I would love to hear them. We’re hopefully getting his DNA tested next month so we can find out. But seriously. What is he?

Bonus:

My other dog Baby, half chihuahua and half jack Russell.
