What breed could my puppy be?

First pic, he looks part Polar Bear 😁
Yeah, could be St. B/Pyr mix.
Very, very cute.

A Great Pyrenees cross, Saint Bernard cross, or even Newfoundland cross is a possibility, depending on how big he is. Australian Shepherd cross is another possibility is he's on the smaller side.

He is huge already! I swear he is like growing an inch a day! His back paw is already 6 inches! He is 13 1/2 inches tall.And laying down he is about 25 inches. And he is supposed to be 13 weeks. But I believe hes a little younger from doing research about him teething and stuff. Is that big for a 13 week old puppy??

What a cutie! I'm sure he's going to be an large - giant dog as an adult at that size.

You might not have been deliberately lied to, especially if he's from a shelter, since someone may have been mistaken about the breed/breed mixes of his parents, but he is definitely not just rottie/pit, though it's possible he has some of either (or both) in there. Genetics is wild sometimes with how it presents in breed mixes, especially once you get multiple generations of mixed breeds.

It can be really hard to guess breeds on a young puppy, because they don't have all their adult features and build yet, and you can't judge what their adult temperament is like. But I'd say St. Bernard or one of the big livestock guardian breeds (like Pyr) is quite possible!

LOL looks nothing like a rott pit. I agree with the pyr x st berner, maybe a bit of collie because of the sable coloring. ( I think thats sable? ) Such a cutie <3 Looks like he will be MASSIVE by the size of those paws!

@Papa'sMommy0608 I think he could be a St. Bernard/ Great Pyrenees mix. By his paws though I’m guessing he is gonna get big. He is so adorable though!!!! 😍I love him My dog is an adult know and some days I miss him being a puppy others I don’t lol😂
