Dog First Heat Cycle Bleeding

Reader Question - Dog First Heat Cycle Bleeding

I have a 8 month old female Jack Russell Terrier. She came into heat around 4m when we noticed a spot of blood, she then had it again around 6m. She is now 8 months and has seemed to be on heat for the past week, leaking blood very frequently.

She is constantly licking herself down there and won't leave it alone. I have checked it out and it isn't too swollen but I can literally see the blood come out and it's that noticeable.

am very concerned as I don't know if this is normal or not. I did speak to a vet when she came on heat for the second time and he said its nothing to worry about but this time I am worried due to the amount of blood she is losing.

Is this normal? If not do you know what it could be? What shall I do? Ellie

Vet Suggestion Bleeding during dog first heat cycle

Hi Ellie,

Some dogs do bleed a lot when they are in heat and the bleeding can persist for a couple of weeks or even longer in some cases. Only rarely is it a sign of a problem.

I suspect what you are witnessing is your dog’s first true heat cycle. Of course, if you are really worried, it’s never wrong to bring her in to your veterinarian for a check-up.

When dogs have heavy bleeding during their heat cycles, it can really create a mess. Doggy “diapers” help, if your dog can stand to wear one. Your best option is probably to have her spayed as soon as this heat cycle is over.
