I haven't looked at the website but I can third the red flag on early spay/neuter. I expect it's to make sure that their pups don't get bred regardless of registration status. That's understandable but it ignores what's being learned about the increased health risks with early spay/neuter.
This will seem like a small study but it's part of several years, multiple breeds worth of data. There's a lot of information online. Just search for "risks of early spay/neuter poodle".
A link to a recent study:
Main findings Standard Poodles. The complete dataset totaled about 350 cases evenly split between males and females. Within each gender, 70-80 percent were neutered or spayed.
Hip dysplasia does occasionally occur in gonadally intact males and females (up to 2-3 percent). There is a modest, non-significant increase in this joint disorder in males neutered at < 6 mo. No other joint disorder increased with early spaying or neutering however, which is a contrast to our published work on Labs, Goldens and German Shepherds (doi’s: Long-Term Health Effects of Neutering Dogs: Comparison of Labrador Retrievers with Golden Retrievers
A cancer of concern is lymphoma, which was not diagnosed in either male or female intact dogs but was diagnosed in about a quarter of males neutered during the first year: a significant finding (p < 0.01). There was a modest trend for females spayed before one year to have the cancer (non-significant).
Addison’s Disease did not occur in any intact males or females, but females are at risk for this disease when spayed before 6 mo., where over 10 percent were diagnosed with this disease: a significant occurrence (p< 0.02). Males neutered before 1 year seem to have about half the risk of females for this disease (nonsignificant).
Bottom line: for males, consider delaying neutering until they reach the age of two to avoid the increased risk of lymphoma, hip dysplasia and Addison’s Disease. For females, delaying spaying females until they are at least a year old seems to avoid increasing the risk of Addison’s Disease, and waiting until 2 years avoids the possible increased risk of lymphoma. Delaying spaying does not appear to increase the risk of mammary cancer, and even leaving a female intact raises the risk to only 4 percent.
Maybe the breeder isn't aware of where the science is leading, so if you're interested in a poodle from them, it might prove to be a beneficial discussion for you both.
