tAs long as she didn't get bred or is going through a false pregnancy, most dogs will shrink down within 2-3 weeks or so months from the heat cycle. It should be noted they will never shrink back to the size they were prior to here heat cycle. Since her teats and vulva are still swollen, I recommend to have her examined to find out if something is wrong or if she is pregnant. I do recommend to spay Oakley unless she is planned to be a breeding dog. There are many health and behavioral benefits to the procedure. I hope this helps and please feel free to post any additional questions.

    It's normal for the mammary glands and nipples to be larger after a female dog has gone through her first heat cycle, similar to the changes that happen in humans after puberty. :) So this is likely perfectly normal. But if you're concerned, you could always opt to have your regular veterinarian take a look at her in person to make sure everything looks the way it should.

    If Nakkita was kept apart from the male, it may be she isn't pregnant. It takes time for the vulva to go down and the nipples do not return to their previous size after a dog goes into heat. Keep an eye on her for now, and maybe in a few weeks, take her into the vet for a check up. I hope this helps.

    With that degree of swelling she is very much in heat and must be kept isolated from all other dogs (if she has been out in the last few weeks it is possible she may have been mated already). I would contact your vet to discuss options if you do not want pups and there is any possibility she may have been mated
