What is the typical size of a terrier mixed with a white Pomeranian dog?
I have a dog that supposedly half white terrier and half Pomeranian and I know that these dogs are separately about 7-12 inches, 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.
by white terrier if you say a West Highland White Terrier while you are dog is probably in the right range, My Westie is the height or slightly shorter.
