Kind of looks to me like they're smooth collie and possibly great pyrenes. I definitely don't think a border collie as the hair is short. But on ralph i can see the square snout and and a few other traits of pyrenes. if you're wanting a longer coat though, these pups would be fluffier at this point. At 4 months they look very short/ small to be great pyrenes, that may just be the picture angles though. He'd be my pick out those pups though. he's very cute.
Um, border collies can have smooth coats. Definitely don’t go by length of fur when determining if the pup has BC. I could easily see BC and great pyr in him. Why do you question the foster mom? Does it matter to you what breed the dog is?
