This is probably a ridiculous question but when someone finds a stray female dog that doesn't have a microchip or identification, can they tell if she is spayed?
I ask this because I found a female mutt and have had her for 3 weeks with no response from any owner. She doesn't have a chip or tags and nobody responded to the fliers or ads. If I keep her or place her, she has to be spayed. My female is spayed and doesn't have any sort of visible scarring. I brought her to the vets around here in hopes that they would recognize her but I have a feeling she was left by a summer person, maybe intentionally. If I brought her again, could the vet be able to tell if she is spayed or do I have to wait to see if her heat cycle is present?
