14 answers  How Do You Know If a Female Dog Has Been Spayed  I
just got a new dog for my daughter they did not know if she was
spayed or not. She is 3 years old and I was wondering if anyone
knew how to tell if a dog had been spayed?  What can I do next?
Featured Answers  Hi A., There should be a small scar
near/behind her belly button. If that's hard to find you can
either take her to the vet or wait and see if she goes into
heat. My dogs scar is obvious...but then she doesn't have much
hair. Good luck.  More Answers  They should have a scar around
their belly button area.  Usually, if you roll the dog over onto
her back and rub gently over her lower abdomen, near her hind
legs, you should be able to feel a scar line bump if she was
spayed. It might be harder to tell on a smaller dog. Any vet
should be able to tell. If you haven't taken her to the vet, I
recommend you take her immediately so she can get any shots,
heartworm test (treatment can be very expensive if she has it),
and on heartworm and flea prev
