Rocky is a three-year-old Maltese Yorkie mix is our best guess he is very sweet once he gets to know you and very affectionate but he is a slow warm-up so at first he is scared and so he can seem aggressive, but I had him less than 12 hours and he was asking me to pet him so it's just at first that's why I would not want him to help with young children for more information.
