yes, we have one with our three dogs and it is wonderful. It doesn't, however keep other dogs out. Depending on the size of your yard, I would definitely recommend it.....but I recommend having it professionally installed.
The only experience I've had is with the neighborhood dogs on them coming to visit my house. One absolutely, georgous, chocolate lab stud came out regularly with two collars on.
Two other labs would swim the creek and visit quite often. I'm not sure if they didn't have the fence charged or the collars were without batteries. :shrug:
Joggers won't be able to tell your dog is contained, and you might almost get punched in the face or cussed at by a passerby.
