It is so much better where you can pour out the urine and disinfect than using the pads because it still leaks on the floor or carpet.. Also these animals are suffering going in the cold, they will get arthritis. Think of when it is raining and snowing and you have to go outside to take them to the toilet well this dog toilet mat is perfect for the house. Glad someone is thinking of them in this way and not just for training it is also good for the wintry and raining days for your dog .
