Hi and Welcome! I'm sorry that it's under these circumstances.Moyen/Kliens even more so.
I want to offer a caution on finding a Medium (moyen/klein) poodle in the US and Canada. That variety is not recognized by the American Kennel Club nor the Canadian Kennel Club so any poodle over 15" but under 20" will actually be an oversize mini or a small standard.
There are only a very few breeders actually importing the Medium variety from Europe and breeding them, and doing the proper health testing.
Many offering moyen/klein poodles simply have oversize mini's, small standards, or are interbreeding mini with standards, a practice not generally recommended. Poodle varieties really are a spectrum. It's true that the height parameters have changed thru the years since breed standards and breed registries came into being. They're sttill different in North America and Europe
