yes microchipping would be a great thing to get done, especially with a basset who when she gets away will just keep going on a scent. It's simple, my vet offers to do it when they get spayed/neutered but they can do it anytime. It's just like getting a shot. Whenever a shelter gets a dog they check for a chip and if your dog has one he goes home, if not...depends on the shelter he'll get a certain amount of days to see if someone comes to get him then either gets put up for adoption or is put to sleep. If a found dog is brought to the vet or gets injured and is brought to the vet they will be checked for a chip. It's something you should definitely do!
