@takoda Frankly I think you have made the right choice, even though I can appreciate it is a hard choice. The “breeder” is not a reputable breeder, which is why due diligence is everything when choosing a Basenji, or any animal.
Don’t let it put you off and if you want a good dog my advice is find a good breeder and look for a 1-2 year old.
I find it ironic that 1-2 year old dogs are sometimes looked at as “used” and are usually a little cheaper. No potty training or accidents, past the chewing destructive stage, already have their personality so you can decide if they will be a good fit in your home. Not to mention all the first shots done and usually much more socially stable.
In reality, I would much rather pay twice the price for a one year old. And they are easier to find.
