Jagd X Whippet or Jagd X Grayhound??
Has anyone ever seen one of these crosses. If so could you post a picture or provide a contact?

Re: Jagd X Whippet or Jagd X Grayhound??
Hello Dan, we had Whippets for many years and they were some great dogs. Coursing is a lot of fun. I was going to contact you and ask if you know of anyone who has all Merle litters, every time with Leopards? I would be very intrested to hear from them.
Thank you.

It's not possible, many have tried. You can get a high percentage with some pairs but anytime you breed for color, you sacrafice ability and I wouldn't suggest it. The fact that not very many people breed b&t to b&t is evidence that there is still to many folks worried about color but hey, that's not likely to change anytime soon. I've only had two litters with nearly all merle dogs.

Dan, Not me you.
Scientists at Texas A & M university have discovered a mobile genetic called retrotransposon responsible for the merle mutation in dogs starting in 2006.( You can look it up for more details.) There is no such thing as blue merle just a merle gene. The merle gene lightens what normally would be dark but in patches scattered randomly throughout the body.
I will not go into all the details because it will guarantee health problems in the offspring. Breeding all merles can defiantly be done and I know how to do it but there’s a high probability of health issues.( Blind, deaf and more.) To start you would have to have above average related dogs and work with someone who has a very good understanding in genetics.
If you took an average of many litters you would find breeding Merle to a full color the offspring would be ½ merle and ½ full color. (By far the best breeding for most.) Merle to merle the offspring would be ¼ full color (mm),1/2 merle( Mm) and ¼( MM) homozygous merles.
The merle gene also can lighten the iris of the eye, again changing dark to light but apparently having no effect on its vision.

Merle to merle mating in dogs
Following a recommendation from the Dog Health Group, the General Committee has agreed that, with effect from 1st January 2013, the Kennel Club will no longer accept the registration of any puppies for any breed that are produced as a result of mating two merle (dapple) coloured parents together.
The merle mutation is a dominant mutation that causes the characteristic merle or dapple colour pattern in a number of breeds. It is also known that there can be associated health risks in those dogs that have the merle mutation.
Many breeds have lived with the merle gene in their population and have avoided merle to merle matings for many years. Some breeds have successfully requested formal banning of such matings and the Kennel Club will not now accept any litter for registration where both parents are merle for Shetland Sheepdogs, Dachshunds (all varieties) and Beaucerons (although these are called tricolour).
In the breeds where merle is proven to not occur naturally, the Kennel Club will not register any dogs that are merle coloured – these include Chihuahuas (Long and Smooth), Staffordshire Bull Terriers, Bull Terriers and Bull Terriers (Miniature). In addition, the Kennel Club will not register litters from Chihuahuas where one parent is merle coloured.
Merle patterning, patches of lighter colour appearing in the coat, is the result of the M gene in the dog. There are two alleles of this gene: MM (merle) and M+ (non-merle), with merle (MM) being dominant to non-merle (M+). In some breeds, the effect of the merle allele (MM) is termed ‘dapple’.
Unfortunately, the effects of the merle allele (MM) are not confined to coat patterning and we know that there can be an increased risk of impaired hearing and sight associated with it, particularly in dogs that are homozygous for MM (dogs that carry two copies of the MM allele).
Due to the associated health concerns, it is not believed that serious breeders would intentionally mate a merle to merle but the commencement of this restriction in January 2013 allows breeders time to readjust any planned breeding programmes.
