Please help to identify these two toy dogs

[Tammy]

I have two small plastic dogs with magnets in the underside of their bellies.  I believe the magnets extend up into the mouth of both (definitely the cream colored dog).  The hind legs are moveable on both.  The head on the cream colored dog can be turned.  The darker colored dog's head isn't as mobile & it has hinged jaws. They are 1.5"-2" in height & length without the legs extended.Could these be prototypes?  What are they?  Thank you in advance for any assistance.   
I don't see where I can attach photos....
