Dogs should never eat fish bones. Choking and digestive problems can occur.

Yes but they can also pass down any bad genes from their past
Most likely yes, but if you allow inbreeding later on down the line there may be genetic deformities. It should be discouraged, as to keep the gene pool wide and deep. This should be avoided, I agree. I have a dog who is a result of an accidental breeding of mother to son, and he appears to have vision problems, as well as issues with aggression to other dogs and his intelligence level. This is only one botched breeding. With repeated breedings of closely related dogs, who knows how bad the dog might be?
get them fixed at the vet
yes
cold water
About 5 to 20 min ... is a normal mating duration.
Yes the well trained Bengal cats and Boxer dogs usually stop on their own when mating.
Hard to imagine their mating rituals being called dances, but yes, they do.
