What breeds are Jake?

I don't see Pittie or Dobie whatsoever.

He reminds me a tiny bit of my Nala who I've guessed to be Lab/Dane and she is near 70lbs.

Nala has a short, square muzzle and dewlaps to rival a mastiff. I think chances are fairly large that a dane mix would have black pigmentation around the muzzle also.

Funny what we all see. I actually have a Greyhound/Pit, doesn't look like him.

I see Great Dane/Lab/Greyhound possibly.

It's always hard to tell just from pictures because the angle of the camera, the lighting etc can really affect how a dog looks. This one in particular is where I saw dobie. Give him black and tan markings in this photo and he'd be an uncropped dobie, the face shape looks nearly exact. Some of the others his face doesn't appear as slender. So like I said, can be hard to tell sometimes without seeing either lots and lots of pics or seeing him in person :)

My 1st impression was Dane. Yellow lab I can see, I can't see Dobie at all, I had a uncropped Dobie many years ago and his ears were droopier and rounder than Jake's. It's really hard to tell but it's fun to try and guess.

He looks like Doberman/Labrador. That's all I see. But that's just my opinion.
