Saddle pattern tri can be seen in many different was. . They look like "heavy" tri colored dogs to the untrained eye but a tri colored dog has markings that have a definite ending and saddle patterns kind of blend or run. Tri color BOTH parents must carry the gene but in saddle pattern both parnets do NOT have to carry the gene.
The two photos above are the same dog. Q is a sable merle who is out of Suzi and Trip.
Same pup but older
