Do you think the rescue was correct?

We got our puppy Smores back at the end of October from a local rescue who had scooped her and a couple of her sisters up from a bad backyard breeder situation. The rescue said she is a mix of mastiff, collie, shepherd and retriever, but not what kinds of these breeds nor what the parents mixes were. She is supposed to be a large dog and is currently sitting at 37lbs at just shy of 5 months do we think that is accurate. We sent an Embark DNA test in two weeks ago because no one can agree on what kind of dog she looks like. I’ve heard australian shepherd, bluetick coonhound, bernese mountain dog, greater swiss mountain dog, smooth collie, blue heeler, and great dane(which I don’t understand lol). What does she look like to you? Do you think the rescue was somewhat accurate? Will post an update when Embark results are in.
