Pros of a Maltipoo

Maltipoos are wonderful dogs and can be a perfect fit for many family situations.
Temperament: they are loving and playful.
Non-shedding: which means they shed a minimal amount.
Hypoallergenic: they can be a great fit for people with allergies.  But please keep in mind that no dog is truly "allergy free" as they have fur and dander.  Please spend lots of time with a Maltipoo before bringing one into your home to make sure you do not have a reaction.
Apartment size: Maltipoos can be perfect for people that live in smaller spaces.  They are a smaller breed and can thrive in this type of environment.
Easy training: Maltipoos come from two intelligent breeds and because of this can be easy to train.  And they respond well to rewards based training.
Family friendly: Maltipoos love people of all ages.  They are hardy, agile dogs that do well with children as well as older people.
Sensitive: they are sensitive dogs that love their owners and will be great, loving companions throughout their lives.
Exercise: they are a medium energy dog and will enjoy daily play times and walks.

Cons of a Maltipoos

Barking: Maltipoos may be small but they can sure make a lot of noise.  This can be a hard one for some situations and is difficult to train them otherwise.
Grooming: Any mixed breed can result in a mixed bag of fur types.  The Maltese has a straight thick coat while the Poodle has natural curl, so your pup can end up with any sort of coat in between.  The thick and curly can be the most difficult groom and requires a lot of maintenance.  
Separation anxiety: Maltipoos are a gentle and loving companion, they do not enjoy being alone for extended periods of time.
Stubborn: They are known for being stubborn and of course this varies greatly by dog, but they can be won over with rewards based training.
