Rough Collie Breeding

Blue Merle to Blue Merle - YES OR NO

Comments in thus far....

in Germany it is forbidden by law as "agony breeding" to mate blue-merle x blue-merle because of the possibilty to get blind and deaf puppies.
I (and most of the German breeders) totally agree with this law and I think, every puppy, born blind or deaf is one too much.

I would welcome a decision of all breeders around the world, not to do such matings at all.

Best regards,

I am totally against this line of breeding.
My friend recently bred her Blue Merle Bitch to a Tri stud dog from a well esablished breeder.
So in thery my friends litter should have been Tri and Blue Merles but when they were born she had 1 Blue dog properly marked 1 Tri properly marked and 3 Double Dilutes
This proves that blue to blue matings was in the pedigree some where along the line maybe generations back.
You may put a blue to a blue and get properly marked pups but some where in that line maybe in years to come these Double Dilutes will show themselves in the breeding.
I feel very srongly that this should be discouraged as these pups can be blind deaf and have interrnal problems.
What are we as breeders doing breeding this sort of dog?
Some say they do this to inable them to breed a lighter blue merle.
But the question is do we really need to breed these pups knowing that they possibly will have to be put to sleep through no fault of their own.
That responsablity is with us the breeders who should'nt be doing it in the first place.
NO TO THIS SORT OF BREEDINGbreeding.

Didn't realise that this was to be discussed at their agm.

I have always been against Blue to Blue matings. I cannot understand people who, as responsible breeders knowingly breed blind or deaf puppies, under the guise of improving colour. I could not have puppies without eyes or ears, and put them down, in the same way that I always try to rear sickly puppies, even if they are ultimately beyond help.

If you think that a certain blue dog suits your blue bitch, then compromise and use its tricolour brother/sire/son. To me its that simple.

Having read the comments regarding double merle breeding i feel it essential to correct one statement as referred to in the second letter on this topic. ' the possible production of dilutes from a tri to merle mating when there are double merle bred parents
I am astounded that in today's climate where colour genetics are no longer the mystery they were, anyone can actually believe these aforementioned babies were dilutes, i can assure the breeder they were NOT. We have in our breed three types of whites, one is dilute and this can ONLY be inherited by mating two blue merles, the dilute gene cannot be carried as a hidden recessive. However two other types of whites exist, one is the colour headed white as seen in America (and yes it does occasionally crop up in European litters) and the other 'white' is a type of Albino. These are more common than one would think and look very similar to a dilute white. Usually they have blue eyes even when born to two sables but this is not connected to the dilute merle gene. These white Albinos often have liver problems and the tricolour siblings (if any) often have a chocolate or liver colour cast to the coat. However these whites are not blind or deaf.
On the subject of double merle breeding, i feel we have sufficient quality tricolours within the Breed to avoid this type of mating all together. It was sometimes unavoidable in the past where quality was often lacking, but it must be stressed that using an animal from a double merle mating in ones breeding program does not endanger the future progeny of the litter, and it is important to stamp out such ignorance.

ps - would like to add another thought to my letter.

Breeding two blues together does not lighten the colour of the merle, this is a fallacy. The correct clear silvery blue colour is produced from the dilute gene working on a clear black, it is when two dilute genes meet up that over dilution creates white with its subsequent problems, it does not create a paler blue. Pale silvery blue relies on a good clean tricolour gene for perfection. I should know, i have bred over 50 blue merle litters and enjoyed over 30 years experience perfecting this colour.

******************************************************************

Having bred a good number of blue merle litters over the years I would like to make a few practical observations on this controversial subject of blue to blue mating's.
First of all I have never done a blue to blue mating because of the horror of having to put down any white puppies in the resulting litters. This caused me to look at the alternative of only using tricolours and to carefully examine which would be the best tricolours to use to try to get the clearest blue.
There is a school of thought which states you should only use blue-bred tricolours and not sable-bred ones to obtain a good blue. However I have used both blue-bred and sable-bred tricolours when mating to a blue and obtained beautiful clear blue colours from both. The sable-bred ones went back many generations on sable lines. The common denominator was that they all had very black coats indicating that they did appear to be carrying the jet black gene which seems to be necessary to get that clear blue. Interestingly these same tricolours when mated to sables also produced a lovely sable colour as well.
I have in the past used a tri who's coat at first appeared reasonably black but who's colour tinged quickly in the sun and most of his blue progeny turned out to be a disappointing darker, rather smokey shade, some with a hint of fawn in places.
As a result I have no doubt that a tri carrying the jet black gene is the essential factor in producing the correct beautiful blue colour, and that there is no need to run the risks of blue to blue mating's.
However I am unhappy about a hard and fast rule forbidding such mating's and would prefer a written directive on this subject pointing out the pitfalls, leaving it to the individual to make their own informed decision.
As an afterthought there have been incidents of people doing blue to sable mating's in the belief that this too produced a beautiful colour, which also can have distressing results.
I had a determined shaded sable bitch who produced two litters to an equally determined blue dog who helped himself. On the first occasion she had been mated to a sable dog and when well overdue my vet gave her a caesarean to find she had 6 puppies, two sables who lived and four blues, 3 of whom died. The surviving blue was very heavily marked with white, about 50% of his body. I gave him to a friend who eventually had to put him down at the age of 4. His eyesight was poor and his heart was failing, The second litter took me by surprise as I didn't realise she was even in whelp until quite late on. She had 2 tris, 1 sable and 2 blues. One blue was healthy but darkish in colour, the other was pale and emaciated and had to be put to sleep soon after. Three weeks later one of the tris appeared to be mentally defective and after some consultation with my vet, we decided to put this one down too - only two examples of what can happen in my experience but enough to tell me this is not a road to go down either.

"I feel that the recommendations proposed by the club to uphold the legislations put forward by the EEC are the first step to take away our freedom of choice, and also is the first stages towards eliminating blue merles completely, if this step is incorporated into the C.A code of practise, and these issues are applied what will they do next? start to tell us what and when we can breed! no-one who has the genuine interest of this beautiful breed at heart takes the decision to put a blue to a blue lightly and not without serious scrutiny of all the parentage of the mating and with a specific purpose. May be it is to do with the quality in recent years of our tricolour males! who knows. But I think it is a warning as to the future intentions of Government to meddle in what they know nothing about!!!!"

I am very pleased to see this discussion. I was taught 50 years ago, at an early age , by Barbara W. Berg of Sunset Land Kennels in Anchorage,
Alaska of the dangers of blue to blue breeding. She and I both love blues but she always said that a blue to a good tri was the ONLY
responsible breeding.

Several weeks ago I rescued and fostered a 3 year old white Shetland Sheepdog who was both blind and deaf. He is bright, curious, and delightful with a nose he uses like a compass. Shown a pathway once, he never makes a mistake. I can assure you, however, that I do not approve
of the breeding that produced him. There were puppy pictures that came with him. One of the parents was clearly a blue merle so I had to assume
that the other parent was also. The other puppies were mostly domino patterns.

I think blue-blue breeding ought to be outlawed since there are too many people willing to take risks to produce a "pretty blue." The blind
Sheltie was the product of a backyard breeder who probably didn't know any better or who didn't care what the dangers were to the puppies.

There is another side to this coin and a much more sinister one too. Has anyone bothered to read the link on the CA site titled
The European Convention for the protection of Pet Animals. Having a strong personal interest in this wonderful colour variety, and also our Breed in general, i attended the CA AGM to discover first hand the full intent of their proposal. Having listened to the relevant points made concerning the government and European convention i decided to check out this site; it is worthwhile to do so, and i would suggest others with an interest in this colour do likewise. I would also suggest to those interested, read the notes written above the CA code of practice (found on the CA site) where an excellent explanation outlining the reasons for such an inclusion is to be found. It would appear on deeper investigation, this lovely and very ancient colour is indeed under threat, and it is only by using common sense and adhering to these KC guidelines, that i feel this colour will be assured a safe future. Believe it or not, like it or not, we live in a nanny state, and we must learn to navigate its waters if we wish to retain anything at all of the beautiful breed our forebears fought to develop.
Secondly i would like to point out the CA have not advocated or given any support to an actual ban on double blue breeding, but (and quite rightly in my opinion) have stated that such mating's are not to be encouraged.. The CA are not restricting the choice of the individual breeder here, rather they advocate we do not encourage such a practice. Surely this step is to be applauded.

October 2007
After showing and breeding Rough Collies for more than 20 years I felt that I had the experience and judgement to do blue to blue breeding. I took advice from some very experienced breeders and decided it was the right thing to do. Unfortunately this did not work for me and I had white defective puppies within this litter.

After reading on the subject and doing numerous research I vowed I would not do this again. But a few years later I was wanting a litter from a blue bitch which I had and at the time I was not impressed with any tri colour dogs that were on the show scene, so I decide to mate my bitch to a blue dog of my own. This time I had a perfect litter of all beautifully marked blue merles. I have since repeated blue to blue matings on a couple of occasions with dogs and bitches of completely different blood lines to have one total disaster and one beautiful litter of puppies.

I agree with Fern Sargeants views on if you use a tri colour with a truly jet black coat and which carries the correct type genes you will produce some beautiful coloured merles.

If I had my time to come over again I think I would say that I would never do merle to merle matings again, but I don't think I agree with banning the practise altogether. Some of the nicest blues were from blue to blue matings check your pedigrees.

It does not always mean that you will get defective whites.

The "tri" in this breeding was not a true tri-color, but was genetically a cryptic merle. The dog HAD to be for them to produce any double dilutes. For reference, see Dr. Sharon Vanderlips Collie book on genetics.
