I'm not sure if you can really tell in babies, but I saw this little guy at PetCo the other day. He was much lighter and richer in color than the others, and even has some salmon coloring on his sides just before it goes to his belly! It's very hard to get the "salmon" coloring to show, so sorry about that. Maybe if I had a better camera, heh.
I was wondering if he was just a nice normal, or maybe mixed with something else?
I will post more pictures if needed.
Pictures (note that the first few images don't show his actual brown coloring, he is lighter):
Shows his blushing
Belly shot
A little blushing on his markings (you can kind of see the "salmon" coloring)
This image shows his actual colors. ^ If you look at the part of his body in the back (behind his neck) you can see some "salmon" coloring a bit.
Sorry for all of the photos, I had fun with them! I also noticed his tongue is a pale color, does that help determine?
Thanks~
