Male verses Female Maltese

"Which sex makes a better pet, male or female?"  That is a question we hear most often from people seeking the perfect pet.  There are inherent differences in personalities between our male and female Maltese, but either sex will make a wonderful and enjoyable pet.  Here is some information that we have learned from our dogs on the subject.
In the dog pack hierarchy females are usually in charge, determine pecking order and compete to maintain and/or alter that order.  The females are much more intent upon exercising their dominance by participating in alpha behaviors.
Males on the other hand, are usually more affectionate, exuberant, attentive and more apt to seek attention.  They are very attached to their people.  They also tend to be less moody.  They are more outgoing, more accepting of other pets, and take quicker to children.  Most boys are easily motivated by food and praise, and so eager to please that training is easy.  However, males can be more easily distracted during training as males prefer to play, play and play.  No matter what age, he is most likely to act silly and present more puppy-like behaviors.
The difference in size between the sexes is minimal if bred correctly.  Males can exhibit secondary sexual behavior such as "humping" or "marking" and lifting their legs, but boys who were neutered early usually don't ever raise their leg to urinate (unless they mimic other in-tact male dogs markingand copy them - monkey see, monkey do). 
Female Maltese left in-tact may also mark their territory.  They may lift their leg, or simply squat to urinate, but it may still be territorial marking.  This is natural instinctive behavior within the Canine world to ensure preservation and continuation of the species.  Spay and neuter your dog early to prevent these behaviors from developing.  Follow the guidelines and recommendations offered by your Veterinarian.
The female Maltese will usually come to you for attention but when she has had enough she will move away.  The males will always be ready for your attention and always wanting more.  Females are generally less distracted during training as she is more eager to get on with it and get it over with so she can return to her comfy spot on the couch.  The female can be more cunning and resourceful in getting er own way.  She is much more prone to mood swings.  Unless you spay your female, she will come into heat twice a year.  Seasonal heat can be a nightmare, lasting three to four weeks and drawing every male dog in your neighborhood to your door.  During this time she can leave a bloody discharge on your carpets, couches, or anywhere she goes.  She will be particularly moody and emotional during this time.  A walk outside during this period can become hazardous if male dogs are in the vicinity.  She will also leave a "scent" for wandering in-tact males to follow right to your door, where they will hang out and wait days for her return.
It is our opinion that when spayed or neutered, either sex will make a wonderful and loving pet.  Just choose the attributes you would most like to have in your pet.
