Even large neon probably wouldn’t help Buster. The best thing he has going is that nose of his. I bet your Chocolate is awesome! I love those but I get Weimeraners and Labs confused. Hubs and I were rodeo volunteers and saw lots of them both. Great hunters. Very pricey, as you said. About $1200 each when we left 5 years ago.
The Weimaraner is a bird dog, not a retriever. They do look a little like a very pale Chocolate Lab, but the head and body are different. Field Labs are very lean and look something like a Weim, and in fact some unscrupulous people are selling "Silver Labs" and "Charcoal Labs" that are actually Weim/Lab crosses. So it's quite reasonable to confuse them.
If you get a top flight field Lab you can expect to pay $1500 and UP. And for the offspring of a National Field Champion, well, the sky's the limit. I heard that the pups out of Lottie (3XNFC/AFC Candlewood Tanks A Lot) were going for $5,000 apiece, but I never confirmed that with her breeder. I bought a pup from Lottie's breeder, but from a less royal bloodline and much less expensive!
