Firstly, these aren't sprockers.... They are SPROLLIES. This is important because they are the very very best breed in the world.
I wish I had a home for another sprollie now. They are just wonderful.
Dogango, I know you have strong views but other than my pedigree working cocker (who was a gift) I have always had long lived, farm bred cross breeds (or as they were called then.... mongrels)
I view them as genetically less risky as pedigrees that are bred from a more limited gene pool. The advantage of free and rampant promiscuity seems to be healthy pups.
If I bought a pedigree, I would worry about genetic abnormalities. If I bought a cross breed from a back yard breeder that was a result of two poor pedigrees mating, I would worry about genetic abnormalities.... If I bought a farm bred puppy off two healthy dogs I wouldn't give it a second thought.
It would go against my personal experience to say mongrels has as great a risk of genetic abnormality as pedigrees.... and I hardly ask the kennel club for a response on the issue as they monitor pedigrees.
