How do I Know if my Puppy is in Heat? What Owners Need to Know

Are you ready to find out all the ins and outs of your puppy being one heat? Keep reading!

Swollen Vulva

The most obvious sign you can look for that your pup is in heat is the swelling of her vulva. This is caused by an increase in blood flow to the area and will make her genitalia look larger than normal.

Excessive Licking

She’s likely trying to soothe herself as her hormones are all over the place, but this could also be a way of keeping her genitals clean and free from any debris or dirt.


The third sign of a puppy in heat is bleeding from her vulva. It is generally a straw-like color and can be a little inconvenient (especially if your dogs are allowed on the furniture).

Receptive to Male Dogs

You may find that your pup is more open to male company when she is on heat. This happens to even the most unfriendly of dogs.

Agitated, Aggressive, or Nervous Behavior

You may notice that your pup is a little more nervous or agitated than usual when she’s in heat. This is likely because of all the changes her body is going through, and she may not know how to deal with them.
