Ok this will sound funny coming from me miss holistic health but I would have the vet do it if you haven't got medical experance if you put the chip to far in you can lose the readablity.and can cause muscle damage.
The chip is easy to do if you know how, we have used them on our large taxidermy mounts that way if stolen as some have the law enforcement can check it. We keep the # on file and give the paper work to the owner.
