Firstly, the most important thing to check with any breeder, is how experienced are they, do they understand the breed, and breeding, and do they do all the health tests.
A home breeder to me sounds like someone who's just decided to have a litter, so the chances that they actually know what they are doing, what inherited problems there may be, and even good animal husbandry needs to be questioned.
If you are going to look at a litter of Cavachons, then you need to read up on the health problems of both these breeds, as the litter will have the genes from both breeds.
This sounds like someone who has mated a Cavalier and a Bichon, maybe both pets? Please check they have all the health certs if this is the cros-breed you want to buy.
These pups are not pedigree pups, despite what they are sold as (Designer dogs)! and you can get the worst of both worlds as a result.
Just as long as you go in with your eyes open. And don't be fobbed off!
