Often I have mentioned to someone that I have fostered many dogs for SPIN and heard them reply,  “How I wish I could do something like that, but I am not sure I can.”  

DNA and genetics are popular topics these days. Sometimes a petite Mom and Dad have a child who turns out to be well over 6 feet tall. Sometimes the opposite happens; a tall couple produces a petite child. Sometimes in a large litter of dogs there is a “runt” who is much smaller than its brothers and sisters.
