I have one of each and love them both dearly. Each has his/her own distinct personality. Cavaliers are just sweet dogs, male or female. Best to learn about good vs bad breeders. Once you have found a breeder you can trust, it might be that only a male or a female is available. When I decided to get a cavalier, I really wanted a female tricolor. I have two blenheims. I don't ever regret getting my two, even though the color was not my first choice. Blenheim is NOW my favorite color cavtiny
I don't know which to get but I will be happy with either!
