For certain behavior responses this is a wonderful tool to use. When I want to get my dog's attention immediately in chaotic situations it works great. I do not want to use it in lieu of verbal commands or hand signals, though. I prefer the personal bond of human signals.

Pros: With proper training dogs respond immediately

Cons: Can be overused.

For serious clicker training, I'd suggesting spending a $1 or two more and getting a less inexpensive clicker. You'll get a clicker that is easier and more responsive to use and one that is less likely to scare shy dogs.

Pros: They do click. . .

Cons: Overly loud and not as easy to use as some other clickers

I've used numerous clickers over the years. For me, it is the only way to train. The Petco clicker I picked up was a little stiff, making me a split second slower with my response. It is very loud though.

Pros: great for training

Cons: a little stiff

this clicker can do the trick. it's pretty basic with only one tone of click. this works only when consistently used.

Pros: small

Cons: minimal

These are great, inexpensive clickers. They have a nice sound to them and the dogs I train have a positive response to them. I like that if you lose these you aren't out more than about $1.50.

Pros: inexpensive, not too loud

Cons: none
