I have africans, utility toulouse and dewlap toulouse. My dewlaps are my favorite. Looks wise, I love their keels and I think the buff colored ones are strikingly pretty. Personality, they are quiet, sweet, slow, and level-headed. They get along great with my ducks and cats, and co-exist nicely sharing a fence line with my dogs.
By the way, I believe that to get buff, they breed grey dewlaps to american buffs and breed back offspring, etc. to eventually achieve the buff dewlap.
