Can a dog get pregnant in first heat?
Dogs can only become pregnant when they are in heat.
There are three stages of a female dog's heat cycle, which begins around 6 months old when she gets her first heat.
Female dogs stay in heat for around 2 - 4 weeks.
The second phase is when your dog can get pregnant, this is known as estrus.
Although six months old is the average age of a dog's first heat, this can vary widely.
Some dogs can go into heat as young as four months, while larger breeds may be as old as two years before their first heat.
Responsible breeders never breed a dog on her first or even her second heat.
In the event that you want to breed your dog or prevent a pregnancy, there are noticeable signs that can alert you that your dog is in heat: First stage (proestrus).
Your dog's vulva will look swollen or larger than normal.
This is usually accompanied by a bloody vaginal discharge and she may urinate more often.
The estrus cycle has four stages.
The first stage is called proestrus.
This lasts approximately 10 days and it is during this stage that your dog will bleed from the vaginal area.
This is your dog's preparation for pregnancy phase, but she will not want to mate with a male during this time.
When a woman is pregnant, the hormones in her body are likely to alter her scent in some way.
So, can dogs sense pregnancy? Because of their keen sense of smell, it's believed by many that a dog can detect a change in a woman even before she does — but it's mostly conjecture.
The fact is, how long after pregnancy a dog has her next period, or goes into estrus or heat, varies widely.
Most female dogs experience a first heat cycle at the age of 6 months.
Unless spayed or pregnant, they'll go into heat every six months for the rest of their lives.
