As Lola has gotten older, we've discovered something about her. We don't believe she is actually a black lab at all, but rather a flat-coat retriever. We're perfectly okay with this, but it has been quite the revelation as Lola continues to have long curly hair on her ears. The real telling factor was this week when we decided to acquire another pup (a lot of work - we know... did a lot of research beforehand) but this time we actually did get a purebred chocolate lab. They are the same age, but he's MUCH more muscular looking than she is and they have totally different temperaments, even though they are both sweeties! Plus she has a very soft, plush coat whereas our new pup has a more rough, almost wirey coat.
Here is an updated picture of Lola. In comparing it with pictures of black labs and of flat-coat retrievers, we feel very strongly that she is the latter. I have actually ordered a DNA test for her to double-check. Again, we're happy with whatever breed she is - but now we're curious! I think the issue is that we actually got Lola from a farm, not actual breeders. So my guess is that they had two adult black dogs and just referred to them as labs when at least one of them must have been a flat-coat retriever instead. They actually look more like black-colored golden retrievers than labs as adults, though the puppies look very similar in the face until they start getting the curly/wavy ear hair.
I guess I don't belong on this forum anymore haha
