Female dog in heat: How long does she bleed, what's normal, & worry?

A dog's heat cycle lasts for around three weeks, so if she started on February 26, it should be ending soon. It's normal that she is spotting occasionally, and you know when she's out of heat when the discharge stops. Now if the bleeding continues for longer than three weeks or Sophie develops other signs such as anorexia, thick pus filled discharge, vomiting, increased bleeding, and/or lethargy, this is not normal and she will need to see a vet immediately. Good luck, I hope this helps!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! On average during a dogs heat, they bleed for 10 days but it can be 2-4 weeks as well. Any bleeding past 4 weeks, or if Cherri is acting sick, is concerning and she should see a Vet for an infected uterus (pyometra). It sounds like Cherri bled for about 21 days? If she has stopped I am hoping she is now out of heat. You can do an ultrasound around 30 days from breeding to check for fetal heart beats or take an X-ray at day 50 to look for mineralized skeletons to confirm if she is pregnant. I hope this helps and have a great day!

When she bleeds, she is in pre-estrus. This is the time where she prepares for estrus (heat). This means she will be bleeding for about 2-3 weeks, continuously. Then the bleeding gets less and her discharge will be more of a clear red-tinged discharge. This is when she actually will go into heat for another 3 weeks, approximately, and this is where is can conceive. You should wait until about two months after her heat cycle is over before having her spayed.

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! A dogs first heat is some what genetic and breed related. Toy and small breeds may have their first heat at 6-8 months while larger breed dogs like Great Danes may not have their first heart until 18-24 months. I have a client who's lab still didn't have their first heat by 1 year of age. I would expect that Bella at 9 months should have her heat very soon or with in the next 3-6 months. Dogs act slightly off when they are in heat. The vulva becomes prominent and swollen. Then you will see bloody fluid from the vulva. Dogs tend to lick a lot. I hope this helps!

Hi there, and thank you for posting this question. The average heat cycle lasts about 4 weeks, however there is some variation. Typically dogs do not have bloody discharge for more than a week or so during this process. The vulva does remain swollen during this time, and after their first heat cycle it will remain more "mature" in appearance than it was prior. If you plan to spay her I would recommend waiting about 1 month after to allow the internal blood supply to regress back down to more normal size. Best of luck and thank you for using Pet Coach.

No, that is not something that is normally seen. With your pet being 6 years old and a larger greed based on the weight you have indicated, she is really past the recommended age for breeding. If she is still bleeding after nearly 4 weeks and it doesn’t appear to be subsiding, she should be checked out by a veterinarian. She may have a uterine infection starting. I would also discuss whether breeding her any more s recommended. Thank you for using Petco Pet Education Center, formerly Petcoach.

On average, a heat cycle in a female dog will last 2-3 weeks (from the start of the vulva appearing swollen, to vaginal bleeding/discharge to the female no longer being attractive to male dogs at the end of the heat cycle) and generally occur every 6 months although it is not uncommon for large breed dogs to come into heat/estrus only once a year. Some female dogs can bleed for 2-3 weeks (much longer than human menstrual periods!). Hope this helps!
