Please list the top 7 pros of the dogs you breed to get them. Also list the top 7 negatives of those dogs as well. Are the parents related at all. Are they the same breed, or are they purebred at all. There are no right answers to my questions, but the truth will all add into the equation.
Bingo, just knowing that they are litter-mates is not nearly enough information.
If they are an F1 outcross, you can probably do it with no real risk. If they are pure bred dogs with low coefficient, more risk. If they are the product of an already established line, more risk still.
No matter the situation though, what is the harm in trying if you are keeping them all and culling honestly?
You said it right right there...
