Ancient Chinese Statues

Both statues belonged to my grandmother who did a lot of travelling and antique searching. She says they are from 900 a.d.- 950 a.d. but I want to know for sure. Each stand at about a foot, maybe a foot and a half tall and look and feel very old. One is of a man standing happily with his dog, and the other is what appears to be a chinese soldier riding his horse. Any additional information on these pieces would be appreciated and of course the value of these items. Thank You!
