I'd need to vote twice... One white & blue, One white & black... Except the White and Black could genetically be a White & Brindle (long story).


Black is the most common colour in greyhounds, and blue is only a dilute of black (so they're actually the same colour, but a blue dog carries the dilute genes).


I don't believe the hypothyroid is connected to the dog's colour, but it could be a congenital defect... and colour is inherited also, hence the "appearance" of a link.

interesting, Patrick is a dark brindle.

Beth, Petey (8 September 2018- ), and Faith (22 March 2019). Godspeed Patrick (28 April 1999 - 5 August 2012), Murphy (23 June 2004 - 27 July 2013), Leo (1 May 2009 - 27 January 2020), and Henry (10 August 2010 - 7 August 2020), you were loved more than you can know.

It is interesting that the result number for blues (the rarest color) is equal to the result number for brindle (the most common color). Would that show that most of blues are hypothroid?

Stan is black.


But could it be that there are more black greyhounds in general?

Deerhounds Darcy, Duffy, Grace & Wellington, Mutts Sprout & Buddy, Lurchers Ned & Jake plus Ella the Westie + cats. Remembering Del, Jessie, Maddison, Flo, Sally, Stanley, Wallace, Radar, Mokka, Oki cat, Tetley, Poppy & Striker.

I am wondering, if there isn't a genetic predisposition to developing the autoimmune condition that causes hypothyroidism. I know in danes it also seems that the blacks and their dilution blue seem to be more effected. May be a research project......

3 fawns and a brindle so I voted fawn


I remember GreysGalgos comment:


Has Grace ever had her thyroid tested before? When she was younger? True hypothyroidism tends not to come on in seniors. If her thyroid is truly low for a greyhound (remember they run a bit low anyway) she may have what we call "sick euthyroid". That's when there's another illness that's dragging the thyroid value lower than it actually is. The trick is finding the "other illness". If she doesn't feel better soon, you should consider seeing the specialist before a month.


I wonder about this. I know Magic, whose thyroid values plummeted just before she went to the bridge, would support this. Several seniors I've had developed low thyroid, 4 out of 13, and one was gone within 8 months, two lived 2 years and Heart is still going (albiet very slow going) so it's been close to 4 years for her.


I don't believe there is a color connection unless it is by geneology--perhaps related. True thyroid defiency is heriditary.


There is a problem in coats and wellness in some dilution, for instance blues & fawns in Dobes. However, my fawn Dobe had no coat problems and her blue sister didn't either. Genetics I believe. The only Dobes I had with thyroid problems were a black and a red!

Callie was brindle,



now Sunny is a different ball of wax, his was on the low side, we treated him for about 6 months but he became very moody, so we took him off the meds, a year later we retested him, and his thyroid levels are now in the normal range, the vet said that sometimes thyroid meds can be used temperarily to help kick start their thyroid gland into functioning more normally, he is a red and white

Renie is black and hypo.

Greyhound angels at the bridge- Casey, Charlie, Maggie, Molly, Renie, Lucy & Teddy. Beagle angels Peanut and Charlie. And to all the 4 legged Bridge souls who have touched my heart, thank you. When a greyhound looks into you eyes it seems they touch your very soul.

I wonder if it is just easier to tell on certain colors too, like if a black grey starts having browner hair, it is an indication, right?

It looks like there are a lot of black hypothyroid greys out there!


Hershey is a dark brindle. People often mistake him for black at first glance (pic in my avatar)

So far, the poll puts black and brindle at the top and those are the two most common colors of greys. Makes sense, doesn't it? I personally believe there is no correlation between color and hypothyroidism.


Of my dogs, Survey (brindle) and Cutie (black) are hypothyroid. Interestingly, Alpo & Darlin, who are littermates to Cutie are not. Cutie also has the worst teeth of the three.
