At what age, do female dogs go in heat for the first time?

Answer 1

Depends on breed and the individual dog. Some go into heat as early as 6 months, some maybe not until 18 months. Smaller breeds are usually sooner, larger can be on the late side because they mature later. Most dogs though will go into heat between 6 months and 1 year.

To give you an example, my lab didn't go into heat until she was 13 months old.

Answer 2

An unspayed, female, dog will go into heat for the first time at six months old and every six months after that, unless she is fixed or she is expecting. Dogs are a lot of fun though, have a great time!!!

Answer 3

It depends on the dog, but usually 6 months to a year.

Answer 4

Anywhere from 6-19+ months. Usually sooner for small breeds, and later for large to giant breeds.
Each dog is different.

Answer 5

it varies but it's usually eight to ten months. That's usually why vets like to spay them around six months.

Answer 6

for shure before the first year after or during their period.
