dog hair under a microscope

This is done by hoofpic I just copies the info from the horse forum.


Ok first one is 50 cent..a choc/brown...



As you can see the follicle is very slightly colored. The light pigment darkens along the shaft and with some hairs quite dark.

And YES the pigment is loading to one side (as a dun horse does) in more than half the hairs..!! The tips also clear.


Ok a blue...Clear

Ok a blue...Clear follicles and is clear for at least a 1/3 of the shaft ( you can see also with the naked eye that it is clear near the follicle then "colors"

Then these huge ovoids!

The pigment is close to the medulla and the ovoids. Tips are clearish but still has a "dirty" look.

Hoofpickok, If the first one (50 cents) was a horse I would have to say it was a bay or darkish red dun... BUT... the follicle is slightly pigmented so that would usually indicate no dilution. Even a black dun-nearly impossible to tell other than looking under the microscope, has a clear follicle and tip. Now the second dog-the blue one the naked eye is colorless from the follicle to about 1/3 of the way towards to the tip. Then starts to show the ovoids-the big blob things and the pigment going goldish tan. Also the pigment seems to "bleed" from the ovoids and also stays closer to the medulla. I have yet to see this so extream in horse color. The tip contains pigment of sorts in a "strand" form. So in saying all of this I cannot tell you if there is any "dilution" as I need a "proven" dilute to compare with. Bloody interesting though!!! rodeoratdogsThat is interesting! But I thought that the blue was already known to be a dilution and the choc was the one that was debatable?? hoofpick I have no idea about dog colors. So blue is a dilution in dogs? admin Yes, blue is a dilution. In fact, it is on the Dilution locus (D). Brown is the one we were having the discussion about a while back. rodeoratdogs Yes and we were trying to decide if the brown was a dilution or a modifier....right Daylene? Did you see our discussion on the canine side hoofpick? Oh you took the words right out of my mouth Daylene lol, I just popped over to the canine side to post the link to the brown discussion to post it here for hoofpick and you posted. Ok so the lady that bought the pearl puppy from me said she was sorry she hadn't sent me the hairs yet but she still plans to. I hope she does and I will forward them to hoofpick . So in theory should the pearl (diluted choc) hairs look the same as the blue hairs and have the same ovoids as the blue hairs but just a different color???? admin Yes, they should. If everyone remembers that blue cats I sent had the ovoids also which is too cool.

So what I would like to know is if this clears anything up for you Daylene is on if brown is a dilution or a modifier??? Or are the pictures just interesting???

I think this follows what horsegen said in that brown is not a dilution.

Of course the pics are extremely interesting!

.....very interesting. I had a member of another forum I belong to "Decker terrier" read our dicussion on brown and she put it like this....chocolate is not lighter version of black it's the complete absence of black.
