For dogs, the standard site for microchip placement is in the subcutaneous tissue along the dorsal midline (the spine) between the dog's shoulder blades.
Can you feel a microchip in a dog?
In most cases, you can't feel a microchip in a dog when it has been properly inserted between the dog's shoulder blades. ... If a microchip moves around, however, sometimes owners can feel it, especially in smaller dogs with thin fur.
Where did my dog get microchipped?
The microchip is injected under the loose skin between your dog's shoulder blades and can be done in your vet's office. It's no more invasive than a vaccination.
