Ive recently rescued a 5 month old hairless chinese crested male in tact.  I have only had him for 3 days so far, and he is very friendly to everyone.  Today, my daughter and her yorkie nina were playing with ozzy, the crested.  Ozzy snarled at her for a toy.  My daughter of course said no and scruffed Ozzy gently and shown.  Everything was back to fine.  Do I have to worry about ozzy being aggresive or is it just dominence trying to take place?  He will be neutured asap of course, so im just hoping thats the problem.
