Chew Toys

So, if you come to my house and didn't know any better you would think that a two year old toddler lives here. We are covered in chew toys. Every toy known is strewn over my house. We even have a toy basket that the dogs go over to all night as they pull the toys out and distribute them around the house. Then why O why do they continue to chew on my things?? I have two bad dogs, I won't name names. ( Kendra and Fiona) Kendra more than Fiona.. I think Fiona just goes along for the ride, but Kendra.. OMG. In the last several weeks she has eaten the inside of my work shoes. This is where my 400.oo orthodics are, she has eaten my snow boots. she has eaten the rings off the pool cover and the worst is, she ate the wiring that connects the pump to the pool filter and nearly dislodged the pump. We were so upset with her, that we put her in the crate in the garage, where she proceeded to eat a hole in the dog food bag above her and pretty much free fed herself like a goldfish. Now, you might say all of this is my fault. I am clearly leaving my things around the house for her to chew on and am not keeping a close enough eye on her, and I accept that. But really, the pool pump wire? Why in the world would that even be appealing to her. Well, what can I say. She is a challenge, and I am sure that if she doesn't kill herself by eating something toxic she will turn out to be just a wonderful dog. Getting from here to there though may be the question.
