[quote1239458695=BluHouse]Although there is no research in giant breeds it would be interesting to see if variation from the average appears there as well. [/quote1239458695] [size=12]I think there would be variation just by there being an average. Is gestation periods the same accross a specie? It would follow that all Canines have the same gestation period (regardless of size) with variation on both sides of the average - me thinks. Thanks for posting the research studies in your post Robin. I will see if I can find them and read them.[/size]
