They do look similar. As similar as two zebras or two calico cats ever look.
There's a big difference between the similarity you expect between twin
dalmatians and twin collies. Most of the appearance of some animals is in
their genes. with others, the pattern is programmed, but the particulars are
an emergent property. If you want the clone to look exactly like the
original, better start with a breed where the appearance doesn't vary much
from individual to individual.

Human twins don't have identical fingerprints. It's the same principle.
