Breeding blue bitch and red male Staffordshire bull terrier

[dawnb12]

I'm intrigued to find out what colour puppies would be produced if someone bred a kc registered blue bitch (white cross on chest) and kc registered red male (white front paw) both got amazing bloodlines. With there Inbreeding Coefficient (COI) only being 3.6 percent. Which i believe the lower the better.

Colour i cant help as im not sure how simple it is in Staffies without knowing colours in pedigree & DNA colour testing .
As to the COI it again is as simple as lower is better & hopefully no breeder goes by that theory alone .
I do know in the UK many have that mindset yet within my breed  dogs in a pedigree of hips scores up near the 30 OMGno BAER testing  but brag about the COI being low has truly screwed over the concept on know your pedigree

By KC do you mean Kennel Club England?

On your dog's pedigree are the colours of the dogs mentioned? It is possible, depending on the colours of the grandparents that you could get some washed -out unhealthy looking and non-standard colours from the combination of Ay and d genes. Is there a recommendation that blue should only be bred to black, as there is in the Great Dane?

Colour should usually be the last thing you consider when breeding but because you mention blue, are you familiar with colour dilution alopecia? 

 

The most important thing before breeding would be to know as much as you can about not just the proposed parents but also their relatives. 

I put it this way: the dog you know and love is just one hand of cards in a big deck. The relatives will show you what other cards might be in the deck but when you breed you will be shuffling those cards and hoping to get only the good ones.

usually blue to gold/red would be all black puppies, unless the red/gold carried a blue dilution gene, then some could be blue.  Or the blue carried only one black gene then some could be red/gold

 

only way to know what they carry is a dna profile done

 

which is a good idea anyway, you sure dont want puppies with two copies for PRA or PLL

just for starters. the profile will give you who is clear, carrier or two copies for many conditions

How was COI calculated?  It's possible that a 5 generation COI looks good but a 16 generation COI is a disaster.  I don't know if line breeding was fashionable for Staffies in past decades.  DNA testing is preferred if a pedigree that goes back many many generations can't be found.
