Is wireless invisible fencing or wired in-ground fencing better for one golden retriever puppy?

What about plain old chain link or hog wire fencing? I’m curious as to why you want a fence to be electric?

Personally, I would never you use an electric fence (I think that it’s cruel. Sorry). I agree with @scamp, chain link or hog wire.

Keep in mind that invisible fencing (usually) works fine to keep your dog in, but (never) keeps other animals out.

If cost is not an issue, why not build a regular fence?

Invisible fence is the norm in this area. They work great to keep your dog in and you don’t have to worry about mowing or the cost of installing a regular fence.
The dog training was awful to listen to. Try to have someone else be home to distract you.

I would opt for chain link fencing to create a play yard for your puppy until you have had time to teach her to stay away from the road and out of the pond.

I too prefer traditional fencing. I knew a man who lost 2 akitas with electric fencing. It was a particularly cold winter, the dogs grew extra thick coats and there was a deep snow cover. The dogs ran right over where the fence was buried and they never felt a thing.

Also as was mentioned above they do not keep other critters or children out.

If you are worried about the pup digging under a traditional fence, bury cement blocks under the fence line or pour a shallow footer, that will deter all but the most determined digger.

If you build a solid fence, put a couple of wire covered “windows” in so your dog can see out. I think they bark more when they can’t see what is going on out there in the world.

I hate electric and “invisible” fences. I think they are much more likely to cause harm. A good, professionally installed chain link fence is your best bet. We had metal shields installed around the bottom of our (yard size) chain link fence, because our dog is a digger.

On top of that, once your puppy learns the rules, the fenced in area becomes a place to put your vegetable garden where it is harder for critters to get in to steal your produce.
