Cats of dogs by breed and colour[edit]

I see you added some categories that sort dogs by both breed and colour (such as Category:Great Dane (brindle) and its buddies). This should not be done: for most purposes, the distinction between a blue Dane and a black one is meaningless as is, genetics-wise, the difference between a fawn Dane and a fawn Boxer. Now, there are two exceptions.

1) Non-standard and/or contested colours -- these are a meaningful distinction since it helps separate standard conforming dogs from those that are not. It's also useful for colour genetics in terms of crop-outs and possible yet non-admissible genotypes when combining admissible genotypes. Additionally, in some cases a non-standard coat hints of non-pure breeding.

2) Recessive black. Since German Shepherd Dog does not have the gene for dominant black, all black GSDs must be recessive black. Only a few other breeds (all much rarer) have the same situation. It's practically our only source of guaranteed recessive blacks until we get photos of tested dogs.

Bottom line: please do not create more dogs by breed and colour cats unless it's a case of non-standard colours or guaranteed recessive blacks. I'm deleting the Great Dane cats and moving their contents back to their original cats, in case you know more such cats feel free to tip me off. --Pitke (talk) 23:11, 5 February 2014 (UTC)

Oh, before I forget. 3) Recessive yellow in breeds where the gene for sable does not exist (for example, the Labrador Retriever). Sable can be told conclusively (any eumelanin on the yellow dog -> sable) but recessive yellow cannot. Even if a dog has cream whiskers on the other side of his head, the other side can have black ones! So it's risky to say, especially from just a photo, if a yellow dog with seemingly no eumelanin is a recessive yellow or not. In the end, it's a similar situation to the recessive/dominant black thing. --Pitke (talk) 23:42, 5 February 2014 (UTC)

Re:File in the category Dog breeds originating in Italy[edit]

Hello! Thank you for your interest in my photos! I think I solved it by adding pictures to the specific category! I greet you! --Nicholas Gemini (talk) 01:32, 12 February 2014 (UTC)
