I was just speaking from experience with Lexi. She sounds just like your dog when she went into heat. My daughter worked for. Vet for three years so I learned a lot from him. She is spayed now
and was 3 and a half when I had her spayed. I have a female pup now who is 14 months and I think we have just had a light period nothing like her moms. So that is why I say they all are different. I would really spay her when you can it would be easier on her I think. ( just my opion). Lily is not spayed because I am still considering breeding her. If I was not I would have at her done before her first heat (at six months). I did tons of reading about females heat and breeding and had a friend who had bred yorkies.
That is where I learned a ton. Lexi first week she would clean herself a little more and sleep a lot. But the second week the vulva swelled and I would see some blood. Third week it would start getting less. Hope this helps
