FenceMate Dog Harness to Keep Your Pets On The Safe Side of The Fence-Dog Safety Harness (Small) Fits Chest 12"-16" (Measure Girth Before Ordering) Improved No Escape Dog Harness

Bought it for my dog the kept finding was out of my fence. The only thing you may have to do is replace the zip ties on the balls as the do break over time. I do recommend

It did not work. My small dog was able to turn her body to get out. A nice idea though.

Fits our puppy beautifully. It does not weigh him down but keeps him very safe. The fun part is watching his confusion as he tries to leave the yard and can’t.

It runs small I have a Shitzu, and a small wouldn't fit I cut the harness strap off and use it as a collar instead.The balls are seeming to work, fingers crossed it continues to keep him from getting thru the fence.

I have a 4lbs Yorke and it was loose on him even set to the tightest. He is able to maneuver the balls around and get out of the gate.

We have a French bulldog puppy, 10 weeks old now (very small) and an inground pool surrounded by decorative black aluminum fencing. We need to keep the puppy out of the pool area (or occasionally in, when we’re in there). The fence slats are 4” apart, so she can slip right through (for now!). She’s too young for a gps collar or electric fence training. So we decided to try this and it works brilliantly! She can’t get through the slats while wearing it. Whoever invented it is a genius and has saved our summer!

This collar is a nice idea and may work for smaller dogs but it did not work for my medium-sized dog. First, the balls sat too high up on her shoulders to provide the horizontal barrier that was needed to keep her from squeezing through the aluminum fence rails. Within days, the pressure of her trying to maneuver through the rails popped both of the balls off, rendering the collar totally useless for us. I would try this collar again if it was only for a small dog, but the medium size is a waste of money.

We bought this for a small breed terrier who was able to get through our already established fence. It worked well for no more than two weeks. Then it broke. We now have a wiffle ball and a harness with another wiffle ball attached that we will never use. We could have made the same thing but I relied on ratings from Amazon and should not have. Lesson learned.

Fell apart within five minutes of my dog wearing it. Clasps broke

I use this on a small chihuahua cross dog to stop him getting through our farm fencing. He gets excited when I go to put it on as he knows he’s going outside. The balls wash well in the washing machine if dirty. The only problem is that they tend to come apart but this doesn’t stop how they work.
