Dog Always Moves to Defecate and Urinate

Admin October 12, 2026

A dog always moving to defecate and urinate is usually not out of mischief but is influenced by physiological and psychological factors, which can be improved through targeted training.

Physiological Reasons

  • Small Bladder Capacity: Puppies under 3 months old have underdeveloped bladders with limited capacity. They may feel the urge to urinate about 15 minutes after drinking water and must defecate within half an hour after eating. Due to physiological limitations, puppies find it difficult to control their excretion time like adult dogs, resulting in inconsistent excretion locations.
  • Lack of a 'Toilet Concept': After birth, puppies' waste is usually cleaned up by their mothers, so they don't need to pay attention to where they excrete. When they arrive at a new home, if the owner doesn't guide them promptly, puppies may not be able to distinguish which areas are appropriate for excretion. For example, soft carpets and sofas may be mistaken as 'safe zones' similar to where their mothers clean up their waste, leading them to excrete in these places.

Psychological Reasons

  • Emotional Impact: A puppy's emotional state significantly affects its excretion behavior. When they feel nervous, excited, or scared, their bodies produce stress responses, leading to loss of excretion control. For instance, a puppy newly arrived at a home may feel nervous and anxious in an unfamiliar environment, resulting in random excretion; excessive excitement upon seeing the owner return home may also make it unable to control its excretion; sudden stimuli like loud noises can similarly trigger stress-induced excretion.

Training Methods

  • Grasp the Excretion Time Pattern: Owners need to observe and understand their puppy's excretion pattern, seizing golden opportunities such as 10 minutes after waking up, 20-30 minutes after eating, 5 minutes after playing, and 15 minutes after drinking water to take the puppy to the designated toilet area, helping them develop a habit of regular excretion.
  • Use Fixed Commands and Positive Reinforcement: When taking the puppy to the toilet, use a fixed command like 'go to the toilet' to create a conditioned reflex. When the puppy excretes in the designated area, promptly reward it with treats, petting, or praise to reinforce its correct behavior.
  • Correct Wrong Behavior Promptly: If the puppy excretes in the wrong place, owners should not scold or punish it, as this may confuse or frighten the puppy and worsen the problem. The correct approach is to immediately take it to the correct place and gently remind it to 'go outside next time' so that it understands the correct excretion location.
