@julia87 How much do you know about Basenjis? Have you met any? It's highly recommended to learn as much as possible about them before making a decision to acquire one. This would be a good place to start.
Do you live in the States? There is a new Facebook group called Basenji (North America). I went to You Tube and saw your precious pups. How cute are they! 3 1/2 you are going to have lots of fun with them! Wish mine were young like that again. But mine don't get into trouble so much anymore............except for T, as he's only 8 and will still mess with you, given the chance.
Hello and welcome. I'm sorry to hear your little b is sickly. I wish her a speedy recovery. There are some great folks on this site with some great and helpful information. Hopefully they can provide some insight to your little girl's illness.
