it clean the house wellI love the four wheels and the power of the unitThese toys are great!! My friend has a destructive chewer furbaby. I got these as a gift for them. Her dog isn't a large dog but he has mighty jaws and teeth. Every week my friend was buying her baby another replacement rope toy. I have a great dane and he loves these, hence my gift to my friends furbaby. My friend only gave Jr. one rope toy to play with just to see how these would hold up. It's been a couple weeks of constant shaking, pulling, tossing, and chewing so and far you wouldn't know he'd even touched it no less play exclusively with it. So far both my friend and ole Jr. are very happy with this product.I like the assortment of toys and my dog absolutely loves them however he was able to chew through each one in a day or so leaving behind a tangled web of the strands that make up each rope. It wasn’t surprising that he did so he is and aggressive chewer was just hoping they’d last a bit longer is all.I thought the dogs would tear it up in no time, they are super chewers. I was wrong, they love the rope just to play instead of tear it apart. I'm pleased with it.Our border collie couldn't figure out which one to play with because she loved them all. We had them all in a basket with her other toys. She sprawled them throughout the house within 5 mins. They all seem to be very well made. Its a great value compared to toys in national stores. I would recommend to others looking for toys for their pets.Holding up to my 8 month old pitbull, so far. It's only been a couple of daysDefinitely not for cane corso's! But still very tight and decent thickness.
