My trainer is holding an open house on Saturday and she is having a rescue group come in and do microchipping for $10 and tatooing for $5 which one is better all of the proceeds go to the rescue I do have my dobes microchipped but all the hunting dogs only wear collars with id tags would the tatooing be a good choice for these guys and how is it done at the clinic we offer microchipping but not tatooing and I was wondering if it was a safe effective way for indintification? and if it is painful to the dogs or do they give a local anesthetic? what information do they put on the dogs leg? and any other information any one may have
