Petsafe Pif-300 Premium Wireless Fence

greatest thing I ever bought for my dog. Don't even have to use static shock, just tone. We put it to the woods side of our house so our dog is now trained to go to the bathroom only in the woods and he can't reach the neighbors yard. This gives him the freedom he needs as a big dog. It's awesome when I go to my father in laws and we can just take it with us and set it up for his yard. Boscoe already knows the rules, easy peasy!

Pros: portable

Cons: learning curve

I love this fence. My dog had a regular invisible fence and he learned that if he ran across the line he could get out with just a quick shock. This fence works better b/c he continues to get shocked when he goes across the line for 30 seconds. He can't hack that and goes back in! The only downside are the batteries that are custom and a little hard to find plus they'r eexpense about $4 a piece.

Pros: No wires, works great

Cons: Doesn't work when power's out, batteries are hard to find
