When Do Toy Poodles Go into Heat?
Toy poodles are known to go into heat at a relatively young age. They can come into heat for the first time as young as four months old.
The exact age of a toy poodle's first heat cycle can vary, but it's often between six and 15 months old. This is younger than many other breeds, so it's essential to be aware of the signs of heat in toy poodles.
Here's a rough idea of what to expect:
- Toy poodles: 2-4 heat cycles per year
- Miniature poodles: 2-3 heat cycles per year
- Standard poodles: 1-2 heat cycles per year
Keep in mind that these are general guidelines, and individual toy poodles may vary. It's always a good idea to consult with a veterinarian or breeder for specific advice.
Understanding the Estrous Cycle
The estrous cycle is a crucial aspect of a toy poodle's reproductive life. It typically starts between six months and one year old, with each cycle lasting around 3-4 weeks.
During this time, your toy poodle will go through various physical and behavioral changes. One of the first signs is a swollen vulva, which will return to normal size within 21 days. Bloody discharge is another obvious sign, ranging in color from bloody red to dark brown.
Your toy poodle may become more clingy and aggressive, with mood swings and loss of appetite. They may also become more receptive to male dogs, frequently urinating to attract attention. The tail position will change, with the tail kept close to the body in the first phase, but flagging to one side in the second stage.
Here's a breakdown of the estrous cycle:
- Proestrus: Swelling of the vulva, start of bloody discharge
- Estrus: Discharge becomes lighter in color, the dog becomes more flirtatious
- Diestrus: Body recovers from estrus, less flirtatious behavior, reduction of swelling, and discontinuation of vaginal discharge
- Anestrus: Reproductive cycle's time of rest, lasting until the next cycle begins
Canine Estrous Cycle Stages
The canine estrous cycle is a complex process, but understanding its stages can help you better care for your furry friend. The cycle typically lasts between 3 to 4 weeks, with most dogs experiencing their first heat cycle between 6 to 15 months of age.

The first stage of the cycle is proestrus, which can last anywhere from a few days to a week. During this time, your dog's vulva will become swollen, and she may produce a bloody vaginal discharge. Some dogs may also exhibit clingy behavior, become more jumpy, or pee more often.
The estrus phase is the mating phase, where your dog is receptive to males. She may need to urinate more frequently, as she's marking spots to indicate her readiness to breed. Her vaginal discharge will slow and may change to a straw color. Since your dog is ready to mate, she will approach males with her tail held to the side but may be aggressive toward other females.
Diestrus occurs directly after the "in heat" stage and allows your dog's body to either return to normal or develop into a pregnancy. Her vulva will return to normal size and vaginal discharge will disappear.
Anestrus is an inactive phase, and no signs of hormonal or sexual behavior are noticed. This phase can last for several months, and your dog will not be receptive to males during this time.
Here are the four stages of the canine heat cycle:
- Proestrus: Your dog's body is preparing for estrus, with a swollen vulva and bloody discharge.
- Estrus: This is the mating phase, where your dog is receptive to males and may exhibit flirtatious behavior.
- Diestrus: Your dog's body is recovering from the estrus phase and is no longer fertile.
- Anestrus: Your dog's reproductive cycle's time of rest, lasting until her next cycle begins.
How Often Does a Poodle Shed?

Poodles are known for their low-shedding coats, but how often do they actually shed? Toy poodles, being the smallest of the breed, tend to shed the most.
Toy poodles can experience 2-4 heat cycles per year, but their shedding frequency is not directly related to their heat cycles.
Miniature poodles, on the other hand, shed less than toy poodles and experience 2-3 heat cycles per year.
Standard poodles, being the largest of the breed, tend to shed the least and experience 1-2 heat cycles per year.
It's worth noting that poodles are considered a low-maintenance breed when it comes to shedding.

Signs and Symptoms
Toy poodles typically begin their reproductive cycle around 6 months to 1 year of age, with a 3- to 4-week heat cycle. This is a crucial time for owners to be aware of the physical and behavioral changes that occur.
One of the first signs of a toy poodle in heat is a swollen vulva, which will return to normal size within 21 days. This is a clear indication that your dog is ready to mate.

Female toy poodles in heat will often show a bloody discharge, ranging in color from bloody red to dark brown, due to the mucus-like discharge. This is a noticeable sign that your dog is in heat.
Toy poodles in heat can become clingy and aggressive, experiencing mood swings and getting irritated at little things. They may also lose their appetite and urinate more frequently.
During the first phase of heat, toy poodles tend to keep their tails close to their bodies, showing little interest in mating. However, as the cycle progresses, this behavior will change.
Here are some common signs and symptoms to look out for when your toy poodle is in heat:
- Swollen vulva
- Bloody discharge
- Clingy and aggressive behavior
- Receptive to male dogs
- Change in tail position
By being aware of these signs and symptoms, you can better prepare yourself and your dog for the heat cycle, and consider spaying or neutering to avoid unwanted breeding.
Frequency and Duration
Toy poodles typically have two heat cycles per year, spaced about six months apart, but this can vary depending on their age and size.

Smaller breeds like toy poodles may cycle more frequently, with some females experiencing three heat cycles per year.
The duration of a dog's heat cycle is usually around three to four weeks, with the estrus phase lasting one to two weeks.
During this time, your toy poodle will be fertile and can become pregnant if she's not spayed.
Here's a breakdown of the typical heat cycle duration for toy poodles:
Keep in mind that every dog is different, and some toy poodles may stay in heat for 2-4 weeks, as is the case with poodles in general.
What to Expect
So, you're wondering what to expect when your toy poodle goes into heat? Well, the good news is that toy poodles, like all dogs, typically have an average of two heat cycles per year, roughly six months apart.
Some females will have irregular cycles, especially if they are very young or very old, so keep an eye out for any unusual patterns. Smaller breeds, like toy poodles, may cycle three times per year, while giant breeds may only cycle once every 12 months.

You can expect the first heat cycle to start around 6 months of age, and it'll last around 3-4 weeks. During this time, your toy poodle will be ready to mate and looking for dates, so it's essential to have a plan in place to prevent pet pregnancy.
Spaying is the best way to avoid pet pregnancy and the whole heat cycle. While it's preferable to spay a pup before their first heat, you can always talk to your vet about the appropriate plan of action for you and your pup.
Here's a rough idea of what you can expect in terms of heat cycles:
Keep in mind that every pup is different, and your toy poodle may be on her own timeline.
