If you declare a carrier as p(ositive for dwarf)/n(negative for dwarf), it means that in an egg or a sperm there is only one p or one n,  in combining two carriers you get the possible pairings p/p, p/n and n/n. what means you can get negativ (no dwarf gene) dogs by pairing two carriers. The only problem is you might get some p/p out of this pairing.

 This means each dog should be checked individually wheather it is 
nn, 
np or 
pp. 

 No shortcuts 

, as usually in life 
 
Thanks for the explanation, Ina.
