Well, my sweet little Haley is 5.5 months now and she will be getting spayed next week (sigh). I also told them they could micro chip her at that time. Do people here typically microchip your Rotties? My previous dog never had one and I am wondering if this is an absolute must do or more optional. Also, I am searching now to see if there are any health concerns associated with the simple chipping. Any thoughts are appreciated!
