A: The shock that the dog gets when nearing the boundry is about the equivilent to static shock that you may get from getting clothes out of the dryer. It is uncomfortable for the dog, but will not do any more damage than the static shock would. With the delux system you can adjust the shock level, or set it to a beep/warning only mode.
Q: When we first got you to install our fence we only had one dog. Since then I gave my son a dog for his birthday. Is there anyway that I can add this dog to the fences system?
A: You can add as many additional dogs as you want, but you will need to buy an extra collar for each dog that you wish to add.
