A company called Unique Produx created this small series of cute cat and dog heads in the 2000s.  Each animal is sticking out their tongues and have collars around their necks.  The sets stand about 3'' in height with a 3-2 pour hole pattern.  The sets are stamped "Unique Produx Inc Made in China", but also stamped "Carol Eldridge" who must have been the designer.
