I doubt a responsible person would want to breed a dog with dwarfism, it just takes one parent to pass it on. They are more prone to arthritis at a earlier age. In people the life expectance is shorter, I don't know if its the same in dogs.
Not all those who wander are lost.
Life is just a leap of faith.
Spread your arms and hold your breath and always trust your cape.
Two things define you. Your patience when you have nothing, and your attitude when you have everything.
