1. All dogs shed. Some more than others
2. In most cases, breeding is more important than breed, and good breedings are not inexpensive. Find a pup from proven parents from a reputable breeder who understands all the common health issues of your chosen breed and does all the appropriate tests. For example, in Labs, you would want at least hips,elbows, eyes EIC and CNM testing done. And by proven, I mean in tests or trials appropriate to the breed, not just someone's opinion that the parents are "great huntin' dogs".
Research,research,research. This is hopefully a 14-year commitment and a new member of the family. You want to make an informed choice.
