Product review (1 stars): happy pet who never passed up a chance to chase ...
This cooktop made a soft noise when it was turned on.  Our previously very calm dog became hysterical when it was turned on.  He made every effort to leave the house, or get as far from the kitchen as he could.  He would shake, and pant with his tale tucked under him.  After a quick google search, I learned that some cooktops emit a high pitch that only animals can hear.  Our dog has gone from a relaxed, happy pet who never passed up a chance to chase a ball to one that cowers under furniture, and has no interest in playing.  When the stove is on, he will pass up any food offered to him.  It saddens me that we tortured our dog, unknowingly, as it took a while to figure out what he was so afraid of.
