A few months ago MaddiesMommie had both her girls spayed together on the same day. When she picked them up that night she was panicked about the black spot of Maddie's tummy. Turned out that it was a tattoo and the vet hadn't told her about being required to do it. I agree that it should have been discussed with you but you also have to realize that there are a LOT of irresponsible owners and many dogs end up strays or in the pound. It is done for the betterment of the all animals so they do not end of have unnecessary surgeries. Do you know if it is a law in your area? Some parts of the country it is required of all spayed animals to be tattooed regardless if it is the Humane Society or private vet.
I believe that Mardelin previously mentioned about being chipped but I would like to clarify this since a chip would not indicate if a dog were spayed or not. But the tattoo would be there permanently.
Unfortunately, these types of problems are seen in rescues all the time when the scar is so small that a vet is unable to tell if a spay had already been done or not.
