Last Thursday, we took our puppy to be spayed. That evening when we picked her up, we tipped her over to see the incision and just below that, I saw they had tattooed her. I was surprised to say the least. I asked why they had done that and the answer was that although it is a relatively new procedure here in Maine, the reason is that if ever our baby goes astray and is picked up by the dogcatcher, the humane society will know she is spayed. Since having this reasoned out, I am now an advocate of all female dogs having this procedure done. Do you think it's a good idea?
