** 24/10/2014: I'm currently working on some updates to this site, and I'm looking for photo submissions for the following colours/patterns in particular:
- Fawnequin, brindlequin and merlequin Great Danes
- Merles with heavy ticking or roaning on their white areas
- Grizzle/domino/sable in Borzoi, Salukis or Afghan Hounds, particularly brindles
- "Ghost" tan markings on black or liver dogs
- Isabella/lilac brindle or merle
- Birdcatcher spots in horses
- Brindle and roan in animals other than dogs

If you have photos of any of the above that you would be happy for me to use on this site, please e-mail me at jchappellart@hotmail.com. Please remember that all photos must be your own, and I would also need permission from the owner if it's not you. High quality, DSLR photos would be preferred wherever possible!

** One of my other hobbies is collecting old photographs of dogs from 1860 onwards. I am now making my collection available to view online - check out my blog on Facebook. And if you like my rats then check out their Facebook page - Archer and Friends!**
