Just a quick question just a general interest.

How closly can dogs be breed together?

Could two dogs with the same Sire but from different dams be bred or is this two close to interbreed?

Also can two dogs that have the same grandparents but different Dam and sire be breed....

Thank you

Any dog and bitch 'can' be bred together. Father/daughter, Mother/son, litter brother/sister etc. However inbreeding that close is not to be undertaken lightly, and culling may well be necessary. Grandsire/grand-daughter is usually okay as long as they don't show the same faults of course!

Just to add that no breeder should undertake close matings without an very detailed knowledge of all the dogs on both sides of the pedigree - the more generations they have information about, the better

Father daughter.....thats sick!!!! URgh!

I was just curious as I've noted on a few pedigrees that the dogs are very close in terms of lineage and I wondered whether this was safe to do...I tough you would get the same problems that you do in humans?

You'll get whatever problem the ancestors are carrying, which is why it's important to "know" the dogs in the potential pups'pedigree, rather than just their names.

It's not 'sick' because animals are amoral. Such close matings happen frequently in nature, in all species. Close inbreeding cannot create new problems; only reveal ones that are already there.
