Later this month we're having an Invisible Fence installed around our rural yard, something we just have to do because our beloved dog Sophie was hit on the road last April and had to be euthanized. It's a dead-end road with only 2 houses beyond us, but one of our neighbors is new and has a business that now brings lots of cars and trucks by our house. But since the puppy is only 9 weeks old now, I would like to know if you think we could train him to the fence by (say) Thanksgiving. Otherwise we'll have to wait until the snow (which starts piling up in December) melts in April and he can see the flags. By then we will be tearing our hair out trying to keep this lively dog off the road and very tired of walking him. (A wood or wire fence is too expensive for our large yard and not really practical for our rural setting.)
