I have used Sam in two of my breedings and could not be happier with the results!
The first time I decided to use him it was out of desire to do something different. I had been doing straight field line breedings with titled MH/SH dogs that had heavily field titled (FC/AFC/MH..etc) pedigrees. In my previous breedings I was getting some dogs that one owner described as "Einstein on crack!". Super talented and at times a super handful. Plus the looks were just not there. Felt like I was producing something closer to a curly tailed greyhound in the color black. So I went out on a limb two breedings ago and used Sam with my BLF who weighs in at 52-54lbs and is an incredibly talented dog. She has her SH title and has one MH pass, but is retired from the games. She comes from a star studded field pedigree.
So what did I get in the breeding? More then I expected. I train as well as breed so I had the fortune of training five of the 8 pups in the litter. I trained them on puppy programs between 4-6 months and again for formal training in the 8-18 month range. One of the pups I trained all the way thru handling and have the pleasure of seeing back on a regular basis for boarding. The owner of this dog is a avid hunter with lots of land to hunt on. One of the perks of breeding and training is all the invites. I have had the pleasure of hunting with this dog on both upland (pheasants) and waterfowl. He is well mannered in the blind (some of my straight field line breedings were creating some whiners....which I can't stand in a blind). The owner has also hunted this dog on chukars out in Nevada with good success.
My biggest fear in using Sam was loosing natural talent for field work. I was wrong. These pups came out as good or better in the intelligence department and very athletic. I picked up a little bone/structure, a little more hair coat, a slightly broader head (just a little), straighter tails and what I would consider a better on/off switch. They are pleasant to own when they are not busy doing something. One characteristic that came out in every pup was big water entries. I mean high flying belly splashes...they all do it. I attributed this to Sam as I had breed this same female previously to a different male and trained pups in that litter as well.
I was so impressed with the litter that I repeated it. I kept a female pup for myself and a male pup as a started dog project (which is sold). In addition I have had the pleasure of training three other pups in the litter. Both breedings came out very similar.
I feel I lost nothing in the talent/intelligence/field areas using Sam and picked up a lot of nice other traits and looks.
I have plans on using Sam again this winter/spring. The owners at Deep Run Kennels are very professional to work with.
Another CH/MH dog out there that is quite nice too if you are looking for yellow is Kerrybrooks Vince
