Potential Health Risks

A dog that repeatedly raids a litter box may develop diarrhea or vomiting and may be exposed to infectious organisms. Large amounts of litter create additional concerns.

Severity depends on what and how much was swallowed and the dog’s size and health. If the dog develops repeated vomiting, severe abdominal pain, marked lethargy, breathing problems, or collapse, obtain urgent veterinary care.

How to Stop or Prevent It Safely

Place litter boxes where cats can access them but dogs cannot, clean boxes frequently, supervise the dog and reinforce moving away on cue. Do not punish the dog.

  1. Limit access to the tempting material whenever possible.
  2. Supervise your dog in situations where the behavior occurs.
  3. Use positive reinforcement to reward leaving the material alone.
  4. Provide appropriate food, routine exercise and mental stimulation.
  5. Arrange a veterinary check if the behavior is repeated, sudden, or accompanied by symptoms.

When Should You Contact a Veterinarian?

Consult a veterinarian promptly when symptoms develop or a dangerous material was swallowed. Do not try home remedies or induce vomiting without veterinary direction.
