Aggressive dogs with sharp nails might be able to dig through the artificial grass, such incidents are relatively rare, but technically can occur. We always recommend the dog owners to train their dogs not to dig, chew or eat artificial grass: the turf surface is perfectly fine for dog to play on, but any abusive behaviors should be avoided. If you have any other questions or concerns, please call us at 877 796 8873 or email us at
