How do I potty train an adult dog that's never been housebroken?

The principles are the same, but adult dogs may have more ingrained habits. Be extra patient, especially with rescues. Crate training is essential. Expect 4-8 weeks for reliable housebreaking in adult dogs with no previous training.

How often should I take my 8-week-old puppy out at night?

At 8 weeks, most puppies need to go out every 3-4 hours overnight. Set an alarm for trips around midnight and 3 AM initially. Gradually extend intervals as your puppy grows and shows ability to hold it longer.

Why does my dog keep having accidents after being housebroken?

Regressions happen due to medical issues (UTIs, digestive problems), anxiety or stress, routine changes, or inconsistent reinforcement. First rule out medical causes with your vet, then evaluate household changes and return to basics.
