This post is for my own curiousity .
I Read about bobtail boxers today and how they originated but the question I wanted to ask is WHY they were bred ? I know they originated from a corgi and boxer mating but Are they allowed to be shown and also can you tell the difference from a bobtail and a boxer that has had his tail docked if you were unaware of the breeding ?
Are progeny allowed to be bred from now or do all offspring need the breeders permission ?
Also , I believe they are recognised by the Kennel Club but if they came about from a cross breeding what conditions had to be fulfilled to enable the KC recognition ??

Why don't you go to the website where you can see photo's of
bob-tails. http://www.steynmere.com and click on bob-tails button.
Why were they bred? The website should provide the answer
Yes the latest generations of bob-tails are shown, and three were
qualified for Crufts 2003. 2 were exhibited and 1 was placed.
Bob-tails are now actively shown in Norway and some have won well.
Yes bob-tail Boxers are recognised and registered by the kennel club
You may be able to find out on the web site what conditions Dr Cattanach
had to fulfill to be allowed to register the bob-tails with the KC. You need the 'genetics can be fun'
articles that appeared in the Dog World, which will show you photo's of the earlier
generations of bob-tails too, click on genetics button.
If you have any questions you can always e-mail Dr Cattanach.

Hello, yes, the best source of information is going to the 'Genetics" page at Dr. Cattanach's site. A fascinating account of the development of the bobtail Boxer. They are slowly spreading to other countries, and I think in the near future there will be many more bobtails.
I myself have just imported one lovely bobtail Boxer puppy from Norway. They have perfectly valid pedigrees, can be shown, bred from, etc. Our pup's tail looks good and is of perfect lenght. These tails can be distinguished from docked tails if you look closely. The natural bobtail has some fatty tissue at the tip that is not present in docked dogs.

On my Spanish which has a bit of length to her tail she does not seem to have this fatty deposit, only my true short bobtails seem to have this!! Is this the same with your boxers?

I know that some "Perros de Aguas" are born with a bob-tail, but I do not know if it is the same gene that Pembroke Corgies and now some Boxers carry. There are other genes for natural short tails (Bulldogs, etc).
If in your breed the bob-tailed dogs produce an average of 50% bob-tailed puppies, it might well be the same gene. It would be interesting to know (and relatively easy to find out?)

Yes they do produce about 50% bobtail
