Just wondering if there is a site anyone can recommend covering the inheritance of coat colour in dogs. What I want to know is if colours are dominant or recessive and what colour puppies could be expected for different matings. Is there such a site out there?
Thanks

there are quite a few and some are devoted to certain breeds, theres a very good lhasa apso one ive seen.

just put dog colour genetics into google and they will show up, if you add your breed to it you may find one specificaly for your breed.

One of my favourites:

that looks very good. Thanks

A lot of them are breed dependent.  Here's the site for my breed

Yes agree with those who've said it's breed dependent and as an example - tri-colour in border collies is recessive, in shelties its dominant..although not the most dominant (sable), black and white is recessive in shelties and dominant in border collies.  In shelties there are various (USA) web pages which includes a 'coat calculator) where you can test out the likelihood of colours.  In border collies there's an excellent site which you can put in actual dogs and see the likelihood, not only of colour, but also factors such as diseases which there are tests for, plus hip scores, hearing tests etc.

With some breeds there is a merle gene - not a colour although we see it as a colour - where only one of a pairing should be merle.  Doubling merle genes can cause problems with the pups - including hearing and sight, with eyes smaller than normal.  You can have a perfectly healthy dog from this mating (even a double merle dog) but absolutely not worth the risk of blind/deaf dogs.

So basically we'd need to know the breed in order to answer the question :-)

Very interesting. I assumed that colour inheritance would be the same for all breeds. A friend has a French Bull dog bitch who is fawn with a black mask. Her mother was also Fawn/Black mask and her father was a black brindle. Friend is looking for a stud but is not sure what colour to use. She doesn't particularly want to produce the black Brindle as she is not keen on that colour but does like the piebald.

She was wondering if she used a piebald stud would she get piebalds and fawns? or would the dark Brindle come out somewhere.
She also ha a Boston Terrier whose parents were both red, but the bitch is sort of a brown brindle color. Will this bitch produce red when mated to a black  or seal dog or is the red likely to be reccessive? See doesn't want tro breed red dogs as these are not in the standard.

And also as there a more than enough posts already on these boards about the moralities for breeding, health tests, and whether or not particular dogs should be bred from at all I would appreciate it if people could just confine their answers to the question of colour inheritance and not muddy the waters by starting on these topics. Thanks very much.

The best thing to do would be to contact the breed club (and preferably join, if she hasn't done so already!), because that's where she'll find the breed experts who are best able to help with the specifics. :-)

Brindle in my breed is dominant so only one parent needs to be brindle to produce brindle, not sure if this is the same in every breed.

heres one for french bulldogs

acording to that site if she put a solid to a pied she can get dogs that look irish spotting
