Entertainment for indoors and outdoors
Bought this for my arthritic older dog for Christmas. He already understood to bop a target with his paw (taught using clicker-training), so getting him used to this was easy. I would imagine if you've never done any form of target or clicker training it would take a few days for your dog to master this game.
Once they've got it, though, they love it!
The dispenser is easy to fill and set up. However a large dog can easily knock it over - I wedged it between two pieces of furniture to stop my dog doing this. My boy gets so enthusiastic with the button that he 'digs' at it, flipping it over, so I also wedge the rubber-surround that comes with it under a table-leg to keep it in place. The suction-type holder (for use on tiled floors) Is fairly useless. There is a grass-peg to secure the button down on a lawn, (though looks a bit flimsy) or you can hold the button in your hand.
Once your dog knows the button equals food, you could make it harder for the dog - put the button inside a cardboard box, for example, or use the button in place of a clicker to teach 'go to bed' or similar skills. (Placing the toy in a crate could help reduce separation anxiety!)
The treats need to be hard kibble (I used a portion of my dog's normal food, making mealtimes last longer and helping to keep his weight down). You can adjust how many treats are dispensed.
This is a great way to entertain a bored dog in the house, or distract him while you get on with hanging out the washing! It's been wonderful for my arthritic boy who can't manage long walks or chasing after a ball any more, but still wants to play.
All in all, well worth the money, far cheaper than other 'target' based treat-dispensers, and works just as well.
