[QUOTE=Suggest you keep any solo inexperienced basenji in at night when these critters are most active to avoid the vet bill.
As for the invisible electric fence, I would only use one during periods which I was actually in the yard supervising the dog. I know with our dogs, the shock from the collar would not be enough to deter them from chasing a squirrel. Such a fence does not keep the coyotes or dogs at large out. Suggest you purchase a large kennel with chew proof roof and anti dig barrier about the base for period which you desire to leave him outside alone.
Thanks for sharing your experience and advice. Oh my - oh my!! These dogs are fearless - ferocious! So I guess there is no way to control the behavior. I will get a kennel as you outlined for late night/early morning business. The kennel will most likely be handy for other doggy reasons too. Duke just won't be invited out to the fire on those crisp fall evenings - that's it!
Also - we got the invisible fence when Duke was 4 months old - he's now almost 7 months. He's only on 2 out of 10 shock frequencies. He's been remarkably obedient with his boundry. We have alot of squirrels to chase and balls to catch. Whenever they've gone over the line, Duke stops short. (I didn't know Duke was a Basenji when we put in the fence . . . I may not have tried it if I new as much as I do today about him.)
