has anyone had this product to microchip their dog ?If so do they know if it is accepted by the kennel club?

If they are not on the Petlog site they will not be a "partner" if you contact Petlog they will tell you if the chips can be registered with them. Are they the ones made by Avid  & sold as PETtrac ?

yes that is the one

I don't think you can register them with Petlog then

oops should have added that the KC might still record the chip on the dogs records
