I have 3 basenji and they all are different. My oldest female, Bella doesn't offer to even try to leave the fenced yard, but if an opportunity presents itself she's gone! And being a basenji, once she finds a way out she'll repeat what she learned. I had to stop her from digging at one section of the fence where she had found an opportunity. Perseverance and an automatic squirt gun took about 3 weeks and she doesn't bother any more. Since my youngest female, Angel (a definite misnomer) learns by what the other 2 teach her, I used the same method on her with success, but I never let her in the yard with my make, Mick. Mick is definitely an escape artist. No matter what, he never stops looking for a way out. I stopped the digging when they were little and they don't know they could go over the fence; and I don't allow the neighbor kids to climb on the fence for fear they'll learn that trick. But Mick can find the smallest places and squeeze through. I despaired of having to keep him on a chain for the rest of his life whenever he was out. I finally struck on the idea of using one of those medical cones and I works great! You have to make sure the collar is snug enough it can't be pulled off and I check it every time I take it off or put it on for wear, but so far it's working just great. He has to go out alone because the girls pull it off then he's gone, but I can now leave him in the fenced yard unsupervised. But I've watched him, he never stops looking for a way out.
