I have a tiny little dog that doesn't get anywhere near the fence, so the collar doesn't go off and yet the batteries last less than a month??!! Petsafe.. come on.. . get with it.. make a rechargeable version, make it so we can put less expensive batteries in or something. 8 or 10 bucks a month is a bit too much. Don't buy the "little dog collar".   1     2     3   Non User
