I have 3 standard poodles. We have the doggies doors at both the Maine & Florida houses. The dogs have fenced yards at both locations. They let themselves in and out. They have been trained not to go into some of our rooms. Does the dog piddle more then normal during the day?
Is he drinking more then normal? Are you saying you limit his water intake durring the day to 3 cups? Unless there is a medical probblem the dog should have access to unlimited water. An adult healthy dog should be able to hold there urine all night. An ill or geriatric dog may need to go more frequently.
