My little girl (2 years old now) seems to be constantly in season even though she was spayed before she even had season.  The vet has done all sorts of tests (including a very expensive one) which shows that there is no evidence of anything being left behind when she was spayed.  Anyone come across this?

Any help would be much appreciated.

Can anyone help with this question please?

Are you sure its not a UTI?

Has your vet done an endoscopy to see if anything is going on?
