At this point, if you already have the puppy the only thing you can do is work closely with your chosen vet to keep an eye on the pup's current health. Get whatever testing done that the vet recommends, and over time test for hereditary conditions that others have already mentioned.
And yes, there are health issues that can be hereditary - reputable breeders test for these prior to breeding.
Don't be surprised if issues arise over time. It's possible your puppy may never have problems but it's also possible that they inherit a joint disorder, eye problems, or something along those lines. It's a hit or miss kind of thing in puppies with no health testing in their background. Invest in a good pet health insurance plan to cover future expenses and enjoy your puppy in the mean time.
In the future, do some digging when you find websites like this that sound too good to be true. Their website looks pretty and they sound nice, they look like a legit "business" with "staff profiles", they offer financing and shipping, and have the words "vet check" and "health guarantee" - but there are a ton of red flags (again, at least IMO) that would have warned me away. Lack of breeder information, lack of parent dog information, the sale of 10+ breeds and all cross breeds imaginable.... the health guarantee itself (you have to be a member of their chosen vet care and general care app which also happens to require monthly payment, you have to have their chosen pet insurance, full coverage of some things only good for 30 days, etc).
It's an obvious mill or broker, at least to me, but the fancy website creates a smokescreen to distract you from that. Pet stores do the same thing.
Good luck with your puppy!
