I'll answer that question here. Neither is better than the other. It just depends on which is your preference. Mine happens to be boys. . I know some people say girls are easier, but actually I've found boys are.
Girls can walk and pee at the same time and they're harder to catch than the boys.
Don't expect any puppy to be completely trained until they're over 5 months old. There will still be accidents until then. . Both are the same to the person they love. I've found my boys are overall sweeter natured than my girls. Girls can get bitchy as they get older.
