My husband's female, Pepper is more aggressive, independent and bitchy. Marks way more than my male, popcorn. But loves people and other dogs.
My male, Popcorn, is cuddly with me and family. Ok with other dogs or else chases them out of yard. Either ignores people or else, or is A BIG crab with people who push themselves on him.
Trust me let the dog pick you. Each time I was set on a certain gender,either the opposite picked me or else I ended up with the opposite gender, and it worked out wonderfully and I never regretted it for an instance.
