We are due to pick our puppy up in a few weeks and the breeder is going to get the litter tattooed. I had never heard of this so I asked my vet and she said that it is very rarely done these days and in her opinion micro chipping is the better option. The breeder said that micro chips can move and cause problems even causing the dog to be put to sleep. Has anyone had their dog tattoed instead of micro chipped ? Thanks everyone.
