I wouldn't think Lab pups would ever get put down due to their demand, heck most of the shelters I've been to have a hard time keeping any pure bred dogs there for more than a week.

Kyle, if you find a good source with a hunting background or field trials please share. We're planning on picking up a new pup this summer but I'm getting antsy and having trouble waiting. Shelter pups will not work well enough for a working dog for us though, we need them at 7 weeks.
