it's only obvious that some people set higher standards and some people are just easily pleased, but if that was my dog theres no way on this earth i would be breeding out of it at 16 month old, however fit/unfit it was or however promising it was looking, it's simply to young to have been tested properly...
fairs fair though and the dog in proper condition would look a very fine animal, but imo i dont think he's been running all the quarry that he's been killing he looks to unfit and far to heavy...
why are all your mates wanting a pup from him to a greyhound, does he lack speed etc.
