What Pet Food You Use?

[over the mountain]

i love walmart.

i feed my dogs purina one. i pay about 22 bucks for a big bag.

bleedburgundy - i have 2 pure breed mutts. one is from tijuana and the other is from w. va. they look almost identical except the lady is about 15 lbs lighter and smaller. anyways, i did a dna test on my older pup. the results? 10% pitt 10% afgan greyhound 10% sheppard (idk i forgot what the last 10% was). the other 70%? undeterminable.

question - ive heard and read that it takes 3 generations of mating to create a breed. i was told that when 3 generations of mutts have breed, the 4th generation locks into 1 of 7 types of mutts. one being the all tan guys with black muzzles like my pups. is this true? has anyone else heard this before?
