Containment Electric

Electric Fence, which is best?
We are getting a goldendoodle (golden retriver, poodle) puppy (4 to 6 months) and the need for a facility professional dog containment system (aka electric fence). What is the best and what are the main differences between the different types, namely: DogWatch or invisible) fence. (Ps Thanks: We live in IL ~ That can make a difference depending on where the different companies are'm talking about an invisible fence, the kind that dig into the ground. The shelter being taken insists that we have installed profesonally, and a wooden fence is not an option for where we live.
I have the Invisible Fence brand fence. I think it's wonderful. I found the people very knowledgeable and coaches are very good with dogs. I was also struck by lightning and come away with a day to repair the fence. I suggest you get the insurance program they offer. He covers everything and anything that can go wrong with the fence. Should also be perform more than basic training is well worth the money and go out a watch what to do. You will need to strengthen training for a few days. My dog I have it with in 4 days. I had the fence of 4 years and I think is the best investment I ever made.
