When Do Dogs Start Periods?
Understanding Your Female Dog’s Reproductive Cycle
First, it’s important to know that your female dog’s reproductive cycle is often referred to as ‘heat’ or ‘season’. Unlike humans, dogs don’t have regular monthly periods. Instead, they experience two stages of fertility which take place in a cycle that lasts about six months.
- Proestrus: The first stage of the cycle, lasting around 9 days. Your dog might show signs of restlessness, and her vulva might appear swollen. You might also notice a small amount of bloody discharge.
- Estrus: The second stage, lasting around 9 days as well. This is when your dog is fertile and will be interested in male dogs.
When Does This Cycle Begin?
Typically, female dogs start their first cycle between six months and a year old. Smaller breeds tend to start earlier, while larger breeds might not reach sexual maturity until they are two years old. However, these are just general guidelines. Every dog is unique, and their cycle can start at any time within this range.
What Does This Mean for You as a Caregiver?
As a caregiver, you need to be prepared for your dog’s heat cycle. This includes knowing the signs to look for, and understanding how to care for your dog during this time. Here are some tips:
- Keep your dog away from male dogs to prevent unwanted pregnancies.
- Make your dog comfortable. She might be more restless than usual.
- Consider getting your dog spayed if you don’t plan to breed her. This will prevent the heat cycle altogether.
Changes in Behaviour and Physical Appearance
During her cycle, you might notice some changes in your dog’s behaviour and appearance. Here is a table summarizing these changes:
| Stage | Behaviour Changes | Physical Changes |
|---|---|---|
| Proestrus | Restlessness, clinginess | Swollen vulva, bloody discharge |
| Estrus | Interest in male dogs | Discharge becomes less bloody |
