I can feel the chips in all of my dogs. Some are between the shoulder blades and some are on the side of the neck. I know they were all put in the same area when first implanted though. I usually don't notice the ones between the shoulder blades when I am petting them as they are in the little dip, but the ones on the side of the neck are felt very easily. Also some of my dogs have 2 chips. They have a German chip which does take a special reader and an AVID chip |
