Dogs who don’t urinate for a day may end up holding in their urine. This is because dogs who hold in their urine for a long time are prone to urethral stones, cystitis and other diseases, which will affect the dog’s health. Therefore, it is not recommended to let your dog hold in his urine for a long time. Take your dog to urinate at least twice a day. If you don’t have time to take your dog out to urinate, you can prepare a dog toilet for your dog at home and teach your dog to urinate at designated times. At the same time, prepare enough water for your dog to promote urination.
