I'm not entirely sure where they stand and I don't want to make any "vulture-like" assumptions. I'm only going by what they've presented (the biggest question marks being what they HAVEN'T presented).
They do appear to take back their dogs (they have an adult, a "show dog" return that they are trying to rehome, on a must-spay/pet-only contract if she is not going to be shown). Pets are supposed to be sold on a spay/neuter contract. And they were very responsive to my suggestion to link directly to the OFA database to demonstrate that health testing be done…
There just doesn't seem to be any current health testing or showing information for them, so I couldn't tell where they stand. I'm also a little concerned that they seem to be breeding deliberately for "unusual" colors ("This litter should produce some beautiful Brindle, tricolor and Trindle Basenji puppies. We have noticed a big demand for this coloring lately and expect this litter to go fast") when I would think that health, structure, temperament, genetics, and so forth should be more important breeding criteria.
I would love to find more interesting Basenji blogs to add to my blog roll, which is the only reason I fell on their page. But breeder blogs are a whole different matter, and I want to make sure they're legit.
