When I have available adults, if there are any quirks or eccentricities, they will be disclosed and discussed with you in depth before I decide whether your home is a suitable placement for each individual or not.  That being said, there are no refunds on adults.   However, if things don't work out for whatever reason, I will take them back as long as they have been properly vetted (with documents from your vet showing that shots, heartworm preventative, etc. are still up to date) and all of the AKC paperwork, shot records, rabies certificate, etc. that were sent with them is also returned.
