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

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!

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!

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.

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.

No this isn’t entirely correct. She does however have a greater chance of needing a C-section if the puppies end up being bigger than her birth canal. Which is why it’s best to have her examined by your vet and radiographs taken to look at the size of the fetuses. If they are too big to pass, then a simple C-section can be scheduled for the Mama dog. I hope this helps. Best wishes and take care.

Please consult your vet regarding your options immediately. If her eggs do become fertilized, this could be a very dangerous pregnancy for Coco, as she is so small and the male dog is so big. The puppies would likely be so big that she may need a c-section to give birth, and the pregnancy could be life-threatening.

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.
