When will my small toy dog go into heat and when can I breed her?

That is true - typically the first heat cycle occurs around 9 months in a small breed dog but it can occur as early as 6 months. You should make sure there is no potential for her to either escape from your yard or for other dogs to get into your yard to avoid an accidental breeding, and should avoid taking her in public when she is in heat. She will first go through a proestrus phase where the vulva swells and there is bloody discharge: this lasts 1-2 weeks. You will want to have diaper for her to wear to decrease the mess. Estrus comes next and will be when she is fertile and will ovulate - this lasts another 5-10 days but there is no longer any bloody discharge. If you don't plan to breed Mini in the future you may want to discuss having her spayed.

Great questions! Dogs can go into heat for the first time anytime after six months. It is never recommend to breed a dog on their first heat because they aren't fully mature emotionally or physically. It's best to breed them on their second or third heat for the first time. Speak to your vet about screening Mia for potential genetic health problems, and whatever dog you want to mate her with should have the same done. This prevents genetic diseases from being passed to the next generation. I hope this helps!

Males can mate after 6 months of age. Females can be bred, ideally, after 2 years of age. Separating them during this upcoming heat cycle would be recommended if you are not prepared to breed dogs and have a litter of puppies. By her next cycle, both will be more than ready to breed and in the interim, you can gain knowledge regarding breeding and raising dogs.

Average age for the first estrus in a large breed dog is about 6-9 months of age. It is not usual for large breeds to not have their first heat until somewhere between 12 and 18 months of age. So, as you can see, it varies widely when a large breed dog may go into heat for the first time. Some dogs come into heat and don't outwardly show any signs so you may not even notice their heat cycle. My best recommendation is that if you have a breeding bitch that is 18-19 months old and she has not had her first heat cycle, you should have her evaluated by a reproductive veterinarian to make sure she is sound for breeding. Hope this helps. Best wishes.

HI, thanks for using Petco Pet Education Center, formerly Petcoach! When an animal goes in to heat depends usually on the breed. Since Tash is a large breed dog 12-18 months isn't unusual. I would expect Tash should com e in to season soon! Toy breeds tend to go into heat sooner 6-8 months. There is a lot of debate on when to first breed a dog. I know a Veterinarian who breeds her Frenchie's on their very first heat cycle. Some say let them go in to heat once. I am more in the letting them have a heat cycle first. I hope this helps!

Hello and thank you for reaching out to Petco Pet Education Center, formerly Petcoach. An intact female dog, depending on the size and breed, will likely have her first heat cycle between the ages of 6 months and 18 months. If she were bred at that first cycle, she should give birth approximately 63 days after this mating. I hope this is helpful!

Dogs come into heat every 6 months, on average. It is best to wait until Rosie is almost 2 years old prior to breeding her. Younger dogs tend to be a bit immature and have more difficulty caring for puppies.
