I was kind of surprised that it could work for my 85 pound dog, but it works perfectly!! I still use it, it has great battery life, both the remote and collar. Oh and the best part is that we could use it while the sprinklers were on!!! :) The collar is perfectly waterproof and the general quality of the controller and collar is outstanding.

I have used this product on my minpin Moka, and it worked well for both of us. I love the size of the remote - very small and convenient. No complaints about the battery life, and the only reason I rated it 4 star was because of the price! (Posted on 3/27/2013)

I am impressed with the Dogtra iQ. I brought this for my girlfriend bad dog. He was completely out of control before I brought this. I love that the collar is waterproof since he always seems to want to jump in our pool. The yard range and battery life rocks! I recommend this to anyone looking to train their dog quickly and effectively. (Posted on 3/17/2013)

I was having difficulty training my dog. He's a Pitbull, and I'm 5'0. He's a smaller Pitbul but I' also a smaller person. The only complaint I have is the price. But once I used it, I understood why it a little more expansive than its counterparts. Great buy!!! (Posted on 2/10/2013)

The Dogtra iQ is helpful for me to keep in touch. The charging capacity is excellent. The price is also good i searched in so many other websites but got it faithful with good price here. Great quality remote control compared to other ones I have owned in the past. (Posted on 10/9/2012)

What I like most about this product is waterproof. I already used with Nikita and she is always playing around. Once she jumped into the water and I was really worried. But it works perfectly since then. You can always tell a high quality product almost from the moment you inspect it, I like dogtra because it is an extremely durable and user friendly product.

What I like most about it, is waterproof. I used with Nikita and once she jumped into the water. I was really worried but it's been working since then. I am very happy with the dogtra remote control systems previously I have owned Petsafe products which of course where much cheaper, but you paid in quality in longevity the ones I owned only lasted 6 months or so then something or other went wrong with them.
