Surely there could be some less invasive procedure to tell if a female dog has been spayed or not? Goodness for a female of unknown medical history, you could for example wait X number of months to see if she goes into heat, of course educating your client on what are the signs to look for. What about an Xray? It seems like overkill to put a dog under anaesthesia, and cut open, when you are not sure at all. When an Xray or the wait and see approach are so much less invasive.

I would not want a tattoo on my gal for spaying. Why not issue a tag similar to a rabies tag or conjoined with a rabies tag to say this female is de-sexed/spayed.
