A dog can last up to 8 hours without urinating. This is the limit for a dog to hold back its urine. Normally, a dog needs to urinate 3-5 times a day. If the dog at home likes to drink water, then the number of urination times is still high. There will be an increase. Don’t let your dog hold his urine for a long time, as this will be harmful to the dog’s kidneys. The owner can prepare a fixed position for the dog to defecate at home, so that the dog can defecate at any time.
