is my yellow lab pur

Question
Are there any signs that could tell if my lab is pure such as the webbed feet or otter like tail

Answer
There are no outward signs that can tell you if your lab is a purebred or not.  That is why buying a dog with a certified pedigree from the AKC or even the UKC is so important.  That's the ONLY way to know for sure.  

But otherwise, for the most part, if it does LOOK like a lab, I would said it's a lab.
