ahhh those dark haired guys! more breed guesses

Very nice looking dogs.  The first one looks like it has a lot of border collie in it.  The second looks like a golden retriever kinda.  MAybe some lab too, thats a tough one.

I'm wondering if the black and white one is a Large (Grosser) Munsterlander, or mix.

The brown one looks like it could be a Golden/Lab mix.

The first one looks like a Springer Spaniel/ Border Collie mix to me. I'd definitely say border collie, though.

The brown guy I don't have any good guesses. Maybe chocolate lab, border collie?

Oh!  I'd definetly see some Springer Spaniel in the first one now.  The ears look alot like my springer spaniel's ears, and the face looks pretty close too.  I think its a Border collie/springer spaniel.  Clarzoo is right.
 
Im also gonna say the second one is Golden Retreiver/Lab.  The face looks alot like a lab's and the body looks like a golden retreivers.

A straight Golden/lab could not produce liver.  Liver is recessive to ee yellow, which is what all Goldens are (or should be).

Now, you could breed a chocolate lab to a Golden, then one of those pups back to a chocolate factored lab, and possibly get the color.  But then the coat is a problem because smooth (lab type) is dominant over rough (Golden type).

OK, so now you can take the NEXT generation and breed THEM together - chocolate factored, rough factored parents to produce a chocolate rough coated pup.

I think you have to keep the Golden out of it and just go for maybe something like a bird dog/lab/Aussie mix.  There's a little fine-ness about the legs and muzzle that reminds me of an aussie or BC.

The first one is  just amazing.  The bone and head, and those gorgeous ears!  I'm really going to go out on a limb and say I don't think there's BC in that guy.  I don't usually go for the rare breeds but honestly he's too much like those Munsterlanders to dismiss it.

What cutie pies.
The first one looks like a English Springer Spaniel mixed with a Flat Coated Retriever.
 
The second one look to have Chesapeake Bay Retriever in it.

Thanks all, for your replies.

My guess on the "spaniel mix" is springer + maybe....landseer newfie.....I'm looking at the  broad stance of the front legs and that chest- he's got some  type of  big breed in there. Granted, he's not as big as a newf, but then, being a "mix" could  downsize some of the breed's physical characteristics.  He is soooooo gorgeous.  Sorry, I don't see BC in there though.
 
here's the link to his "bio"

As for the Chocolate, the face shape reminds me of a rottie, the color, choc lab, and the tail irish setter. But I have to agree on the Chesapeake Ret. "mix" looks most like that.
