White Terrier

I have a dog that supposedly white terrier and half Pomeranian and half and I know that these dogs are about 7-12 cm separately, but it is about 22 inches. So I just want to know if this is normal or if there is a chance they got her mixed race.

if you mean by a White Terrier West Highland White Terrier, then you're probably dog is in the ballpark, My Westie is that height or slightly shorter.
