I get asked this question a lot, “are my puppies microchipped?”
The answer is no.  Microchipping causes cancer and can actually travel inside your puppy/dogs leg and get lost, yikes!

This is a great selling tool for breeders though, it makes it sound like they are very caring. 

It is very cheap for them to inject the puppies at their home 
before they sell them to you.  (The microchip is small and is just injected with a syringe.)

You have no idea how cheap it is for breeders to buy things like this and also to buy vaccines, cheap compared to what the vet charges you.  When I used to administer vaccines myself to my puppies, I would buy in bulk and pay about $3.00 per vaccine only!
