What a fun group of three!  The first basset has his head down and is happily tracking!  Minor crackling in finish.  Tri-colored, glossy finish.  Has JAPAN printed on bottom.  He measures 5" long by 3" high. 

The second basset appears to be glass and is standing in a showing stance.  He measures approximately 3 1/4" long and 2 1/2" high.

The third basset is also standing proudly.  He's tri-colored with a glossy finish.  He has a sticker on his belly that says, "Napco, Ceramic, Japan".  Written on his body is the number M175"8?".  He measures 5" long and 3 1/4" high.

Great group!
