what is a dilute whippet
Here's the quick version! The dogs below show nicely-pigmented liver and isabella noses, but it's common for both colours For further genetics resources, see the Links page. liver, so a liver dog could appear to be isabella (e.g. This means that a dilute puppy can be born from two non-dilute parents. Given that the modifying environmental or genetic factors responsible for alopecia are unknown, the only way to prevent color dilution alopecia is to avoid transmitting the dilute coat color variant to offspring in susceptible breeds. It certainly seems to occur in most (if not all) breed types. ** Please note that I am not a research scientist, and the information on this page comes from my own knowledge and observation of dogs, observational and testing data provided via e-mail by site visitors, any research papers linked on the page, and the information provided by Dr Sheila M. Schmutz on her excellent website http://homepage.usask.ca/~schmutz/dogcolors.html von Bomhard W, Mauldin EA, Schmutz SM, Leeb T, Casal ML. Finnie JW, Tham VL. Quick Summary! It causes problems with the transportation of pigment along the hair shafts, resulting in the pigment molecules "clumping together" instead of spreading out as they should do. An isabella dog will have the genotype bbdd (homozygous for liver, homozygous for dilution). Greying can also affect Generally the most failsafe way to tell a blue is by looking at the nose. Scott DW, Miller WH, and Griffin CE. There are just two alleles on this locus - D and d (although there are a number of slightly different d alleles that are phenotypically the same). Weimaraner) or have very high incidence of dilute are far less likely to have CDA. The sure-fire way to tell a black from a blue is to look at the nose. MLPH Genotype - Melanin Phenotype Correlation in Dilute Dogs: http://jhered.oxfordjournals.org/content/100/suppl_1/S75.full A potential candidate for non-MLPH dilution in dogs is TYRP2, which is known to cause some forms of dilution in mice, and the phenotype of these mice is certainly similar to the darker shades of blue in dogs. Greying can also affect The coat may be entirely sable or recessive red for example, but if the dog gene (note that the eyes are a less reliable indicator, as some black dogs can have light amber or copper eyes). Nova Scotia Duck Tolling Retriever Club. Any and all black hair on the dog is included. Knottenbelt CM, Knottenbelt MK. Only a dd dog will actually be a dilute, and a Dd dog will be a carrier. whereas a dog with greying will be born black (or liver) and fade as the coat grows. liver, so a liver dog could appear to be isabella (e.g. whereas a dog with greying will be born black (or liver) and fade as the coat grows. Quick Summary! A liver dilute is a light grey/brown and is generally known as an isabella or lilac. It is likely that the dilution mutation occurred very early in the domestication of the dog, and has occured more than once. 2005 Sep; 6(3):259-61. It is, however, the colour of the Weimaraner, and also occurs occasionally in a handful The gene causing dilution in dogs is known as MLPH (Melanophilin). Black dogs become blue when they are dd on the D locus. Dilute Look-A-Likes The colour is likely to be paler than the amber eyes seen on liver dogs. University of Saskatchewan. Colour Dilution Alopecia. This means that a dilute puppy can be born from two non-dilute parents. For further genetics resources, see the Links page. True dilutes are sometimes known as "born blues". levitra The only want to GUARANTEE dilute puppies is to breed a dog who IS blue or a dilute color to another dog who IS dilute. All Rights Reserved. If the dog has any black or liver then it is not a true dilute. A potential candidate for non-MLPH dilution in dogs is TYRP2, which is known to cause some forms of dilution in mice, and the phenotype of these mice is certainly similar to the darker shades of blue in dogs. Miller WH, Jr. Alopecia associated with coat color dilution in two Yorkshire terriers, one saluki, and one mix-breed dog. dog will become blue (aka slate) and a liver (chocolate) dog becomes isabella (aka lilac). The dilution gene also causes the eyes to lighten to amber. The gene causing dilution in dogs is known as MLPH (Melanophilin). The D locus controls the intensity of eumelanin in the coat (and also the eyes/nose/etc). 02 Apr. I won't explain the patterns here as they're dealt with on their own pages, but hover your mouse Dilution may affect phaeomelanin slightly (although this is the source of some contention), but certainly not to the same extent as it affects eumelanin. If the dog is Bb or BB, it will be blue instead. Dilute Look-A-Likes The following dogs are not actually blues. Blue (Dilute Black) Similarly, some breeders claim that dilute dogs should never be bred together. The dilution gene occurs on the D locus. This is a two step process. All eumelanin is affected on a dd dog. Generally the most failsafe way to tell a blue is by looking at the nose. Blues can range from silver to slate or almost black, and it can be difficult to gene (note that the eyes are a less reliable indicator, as some black dogs can have light amber or copper eyes). The photos below show isabella dogs. The dog will pass on d to 100% of its offspring. recessive and relatively rare in the dog population as a whole, so isabella is generally a rarely seen colour. Web. The D locus controls the intensity of eumelanin in the coat (and also the eyes/nose/etc). The photos below show isabella dogs. See the Health Problems page for more information on CDA. Remember that this breed was developed to chase and kill small, furry running creatures. A potential candidate for non-MLPH dilution in dogs is TYRP2, which is known to cause some forms of dilution in mice, and the phenotype of these mice is certainly similar to the darker shades of blue in dogs. Isabella, however, is slightly trickier. Note the fairly pale red (phaeomelanin) areas on some of these dogs. Dilution and liver are both The dilute gene is also notably common in Italian greyhounds, whippets, Tibetan mastiffs, greyhounds, Staffordshire bull terriers, and Neapolitan mastiffs. MLPH Genotype - Melanin Phenotype Correlation in Dilute Dogs: http://jhered.oxfordjournals.org/content/100/suppl_1/S75.full Dilution and liver are both The coat may be entirely sable or recessive red for example, but if the dog
