Additional Description

You just attach their toys to the PhysiPet and due to their natural interaction they will receive a beneficial workout throughout their whole body and stimulate their curiosity, while siphoning off excess energy from boredom and separation problems.
I developed this product with the ability to CHANGE to amount of friction the product has to allow the dog to conquer the toy by exertion allowing the pet to drag the device as not to entice a 'stalemate' and encourage aggressive tendencies.
The internal section of the PhysiPet is hollow for 2 reasons; first to store extra toys, and 2nd to add extra weight adjusting the co-efficient of friction altering the amount of 'work' the pet will have to exert to move the device. All these features adjustable for your specific breed and terrain see it in action at www.physipet.com
