Does anyone know if bitches scent mark ? Mollie is day 9 of her 2nd season,yesterday she scratched her blanket up in her bed and did a small wee on it then stood sniffing it

She had just been out and 'performed' so didn't need to

she then did
a v small one on the door mat and this morning her bedding was damp !She has been clean since she was 4 months . We did take her crate away yesterday as we thought she no longer needed it

though we put it back last night incase that was the problem.
I realise it could be an infection though I feel it is somehow related to her season
