Normal dogs need to urinate once every 10 hours. If a dog is allowed to urinate once every 12 hours, it will easily cause damage to the dog’s urinary system, causing the dog to suffer from urinary stones, urinary tract infections and other diseases. So it’s best not to let your dog pee once every 12 hours. If you don’t have time to walk your dog, you can prepare a dog toilet for your dog at home. This can prevent your dog from getting sick from holding back its urine, and also prevent your dog from peeing at home because it cannot hold back its urine.
