What size male dog is safe to breed with my female to avoid risks?

Updated on September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 6 months and 11 days old | 35 lbs

Hi, I was planning to breed my adorable female Pin Tzu(Mini Pinscher x Shitzu.) But I'm still confused. For choosing the right breed. Because she might be caesarian if larger dogs will be the Sire(father.) Or is it possible to do so? Without getting my dogs prone to danger. Any help will be appreciated, Thank you! Regards, Christian Joshua T. Day #0237 Dr.Balmores Resd., ST. Bernadette Subd., Santo Rosario,Capas,Tarlac,Philippines.

Hello Christian! Mila Mumu is adorable! It is never recommend to breed a female to a larger male due to the increased size of puppies and the subsequent increased risk of dystocia (difficulty giving birth) leading to a c section. I would choose a male who is her weight or small than her to avoid any danger, so pick a breed of male that smaller than she is when she is fully grown.

Please know that it is never recommend to breed a dog on her first heat. That's because she will not be fully mature either physically and emotionally, and that leads to an increased risk of dystocia as well as possible poor mothering. You should wait to breed her until at least her second or third heat (around 18 months of age). I hope this helps!

Is an 18 lb male dog too large to breed with a 14 lb female?

There are probably close enough in size to not have any issues, but it is difficult to say with any certainty. Being mixed breeds, it is possible there may be some possibility that the pups could be larger than the mother. If you choose to proceed, after vet checks of both dogs, have the mother x-rayed about a week before her due date. Your veterinarian should be able to determine litter number and size then may predict more accurately if surgical intervention will be necessary.

Is it dangerous for a small dog to breed with a large dog?

Yes a black lab can breed with a Shih Tzu but the problem is that the lab is so much bigger than your dog, meaning the puppies will be large. This leads to an increased risk of dystocia (difficulty giving birth) and likely an emergency c-section. There is nothing you can do about the owner of the lab unfortunately. I would have your dog spayed after she has her puppies so you don't have to worry about any unplanned matings in the future. Best of luck.

Can my small goldendoodle safely breed with a much larger male?

I would be concerned that this weight difference might result in puppies that are too large for Bella and that she could end up needing a c-section. She could also end up having fewer, larger puppies. I think you’re better off searching for a smaller male.

My large female dog's vulva is small. Is it safe to breed her?

Hi there. Sounds like she may have a hypoplastic vulva. All female dogs can be at risk of having a hypoplastic vulva but medium to giant sized dog breeds have been shown to be at a higher risk. I suggest your friend have his bitch evaluated by a vet before attempting to mate her. Your male could cause serious damage to her. It may be more helpful if you could post again with a photo however, I'm not sure the answer would change much. It is best to have her evaluated before breeding. Hope this helps. Best wishes.

Is a 15-pound male dog too large to breed with an 8-pound female?

Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question. Yes, I would say this is too big. You want the male the same size or smaller than the female. In addition, given that Ellie is only 8 pounds, having a male almost double her size will lead to an increase in puppy size and a much bigger risk of dystocia (difficulty giving birth). I do not recommend mating her with this male. I hope this helps!

My dog is on her first heat. Is it too early to breed her?

Misty is adorable, so so cute! This is a great question! Yes, it is recommended to wait until at least a dog's second heat before breeding them. At the time of their first heat, a dog will not be fully grown, nor will they be emotionally mature, and this can lead to problems with giving birth and mothering ability. By the time a dog has their second heat, they will typically be matured both physically and emotionally, and that will make her a better mother. I definitely would recommend to wait until Mitsy has had at least her second heat before mating her. Good on you for asking for advice first, that's extremely responsible :-)

Is it safe for my small dog to get pregnant by a larger male?

It is likely they will be fine. As long as the parents are close in weight (within 10-15 lbs or so, the puppies should be fine. However just make sure to get radiographs when Pixie is beyond 45 days gestation to ensure the feti are not too big to go through the birth canal. I hope everything works out well for your pet Pixie. Best wishes and take care.
