what color is this beautiful dog considered?

Yep, mahogony sable. The giveaway is the lighter undercoat, covered with dark/black guard hairs, along with the sable face.

This is my forever pup, Timber. He got darker as he got older.

(quite the porker in this picture! :lol:)

A tri would only have smatterings of tan on face (e.g. eyebrows, muzzle)

Notice the difference between Indy and Bacca. A sable might have black accents. A tri will have tan accents.

A bi-black will have no tan at all.

Also known as a tri-factored sable. Meggie's daddy is a sable, her mom is a tri. She seems to get darker with age:

Actually the mahogany Sable is not only a tri factored sable but can also be a bi factored sable. Justice is a bi factored boy, mom sable, dad bi black.
 
How do you determine with a sable what factor it is? Emma's sire is a tri-factor with no white factor. She looks very much in colouring like her sable mother.

Sorry I couldn't get a real clear picture of her.

Well sometimes it is hard. Sables can carry only one black gene either tri or bi. If you have a sable with a black parent and a sable parent. The sable gene came from the sable parent and the black gene came from the black.

If the black dog is a bi you know that your sable is bi factored as there is no other option. However, if the black parent is a tri then is depends on what black genes they are carrying. You know there is a tri gene as they are tri but the other gene(the hidden gene) could be a tri or a bi depending on what their parents were. So which one did your dog get? Sometimes you don't know unless they are bred and produce a bi pup. It can be just as unclear if the parents are sables as the black gene is hidden. You really need to look at the pedigree and then still might not know. Confusing.

Here is my example:

Diva is a tri(Tri/?). Her mom is a mahogany Sable(S/?) same color we are talking about. Mom's parents were a pure for sable and a Bi factored Tri(Tri/Bi). So mom could be a Bi factored or Tri factored Sable we don't know. She has only been bred to a black dog(bi factored Tri) once and 2 Tri produced so we still don't know as the tri gene could have come from the dad. If Diva produces a bi we still don't know as again she could have gotten the bi gene from dad but if she never produces a bi pup when bred to a bi factored dog there is a good chance that she is Tri/Tri and mom is tri factored. The way to straighten it out for sure would be to bred mom to a Bi black if a Tri is produced , you know Mom is a Tri factored Sable. Make sense?

To give you idea how hard it is to determine if a dog is bi factored. Ember's(Bi/Bi M/m) mom is a bi factored Sable(S/Bi). Her dad a blue merle(Tri/Bi M/m). None of his parents were Bis and none of his 4 Grandparents were Bis. The bi gene come from his great grandsire, Ember's great great Grandsire. It skipped down that many generations unknown before it showed up again.

Thanks Dr. Shelli. It is really hard to determine their factoring. I was just curious and wanted to know for my own satisfaction. Any way you look at it, she is loved no matter what the factor and has made our lives much richer by being in it.

Yep just being themselves is enough. There is a genetic test through Vetgen that you can do to find out. Someone asked me if I was going to test Diva so I know. I said nope doesn't matter to me she was bred to a bi factored blue merle and what ever colors I get I get. Color wasn't the reason we bred to the dog anyway. Although I won't be sad if we get a bi blue boy.:smile2:
