Male VS Female, the age old debate. I realize that each person has their individual preference and each personality of each dog is different, but you should never count out a male. People often want females because they are "more laid back" than males. I have to say that is totally untrue. Most of the time my boys are more easy going than my girls. Females are usually the leaders of the pack. They tend to be more bossy than the males and more indepenent. My girls are very territorial of areas they think of as theirs. None of my boys stake claim on a certain area of the bed or a favorite toy like my girls do. I also have seen a couple of my girls that will also mark their territory by peeing in the house like the boys get blamed for. Girls can also be horribly moody, going from happy to ornery in just a flash of seconds. Usually if a fight breaks out it is between 2 of my girls and never my boys. Remamber; there is a reson they call girls "bitches". Also on top of all that you have the cycles of the female to deal with if not spayed. This can be very messy and time consuming as you have to guard your female extra carefully during this time if you are not breeding.
Males on the other hand are very loyal and protective and bond very well to you. They are less territorial than females are can adapt much more quickly than a female to new situations. If a male is neutered early or trained carefully they will not lift their legs.This seems to be the most common complaint I hear about. I have my boys all together in the house, none of them lift their legs to mark on anything in the house we trained them not to but the only time they will do mark is when one of my girls is in heat,(what is normal).
Some Poodles are couch potatos and some live to get up and go. This is something that should be matched to the family the puppy is going to more than a decision that is based on sex.
