Neapolitan Mastiff
This breed of dog initially comes from Southern Italy and was originally used as guard dogs. They are gentle dogs despite their massive size, and can be very affectionate towards children. However, because of their size, the Neapolitan Mastiff can also be quite clumsy, so they can easily accidentally knock over, sit or step on small children by mistake. They also tend to drool a great deal, particularly after eating or drinking, which may add to the mess in the house already created by your children.
Skye Terrier
Skye Terriers originated in the United Kingdom, and are even associated with the royal family. Known for being very loyal, they were originally bred for their hunting skills, and like most other Terrier breeds they can be quite aggressive towards other dogs and enjoy hunting smaller animals. Even though they definitely enjoy the outdoors and need a lot of exercising (though not recommended before they are around 8-10 months old), they actually prefer to live indoors. Like most pets, they need a lot of love and affection, and if they feel neglected they will express their irritation by chewing, barking, and digging.
