What age are dogs when they first come into season?

The age a dog first comes into season, also known as heat or estrus, varies depending on several factors including breed, size, and overall health.

Generally, most dogs will enter their first heat cycle between the ages of 6 months and 2 years old.

Here's a breakdown:

* Small breeds: Often start their first heat cycle earlier, around 6-8 months old.

* Large breeds: May not come into heat until they are 12-18 months old.

* Giant breeds: Can take even longer, sometimes up to 2 years.

It's important to note:

* These are just general guidelines, and individual dogs can vary.

* If you're concerned about your dog's heat cycle, it's always best to consult with your veterinarian.

They can help you determine a normal timeframe for your dog's breed and provide guidance on how to manage their heat cycles.
