    You can, but the quarter horse is more likely to have problems giving birth due to the extreme size difference. Better for the clydesdale be the mother, not the father.

    It would be best to breed a Quarter Horse to a Clydesdale, the mare would have an easier time of foaling than the reverse. Artificial insemination might be needed. Just like breeding a Mammoth Jack stud to a horse mare for a mule.

    You could, but has it been done? Probably not.

      It's been done. Here's a study where they bred shetland mares to shire stallions - https://royalsocietypublishing.org/doi/pdf/10.1098/rspb.1938.0029.

    You can, but it would be safer to do AI. The weight of the Clyde and the height difference will make it difficult and the mare could tear.

    Of course. But if you're asking whether you SHOULD do this, the answer is NO. Because of the difference in size between the stallion and the mare, there is a considerable risk of a serious birth issue in the baby. It's called feto-cephalic disproportion, and it happens in horses as well as in certain other species, such as elephants and giraffe. What it means is that foal is too large for the mare's body to deliver safely. In such cases, usually a C-section is the only answer- and if that cannot be performed, both the mare and foal are at risk of death. Do you really want to RISK that happening?

      The condition has different names in different medical and veterinary literature. Some places it is listed as CPD, others as feto-cephalic disproportion. It's a nasty condition, and it's one reason why certain species such as elephants and giraffe have a hard time reproducing.

    Yes. You can, assuming the mare is a large quarter horse and not finely built. The actual breeding must be handled carefully, but the foal will reflect the size of the mare more than the size of the stallion, and should not be a problem.

    The better question is: should you?

    eta: The issue with this breeding is the effect of the stallion's size on the mare (assuming live cover). Studies have shown that the size of the foal at birth is determined by the size of the uterus of the mare. In 1938, a study was done where shetland mares were artificially inseminated by Shire stallions and vice versa - https://royalsocietypublishing.org/doi/pdf/10.1098... - and many studies have confirmed this since.

      I'd be surprised if it wasn't an experience in all mammals, and other animals as well. Birds sometimes get egg bound.

      But is it more common when a large stallion is bred to a small mare? I've found no evidence of it.
