A puppy bladder physically holds roughly its age in months in hours. Accidents are biology plus missed timing.
Regressions around 4 to 6 months are textbook. Most dogs are reliable by 6 to 8 months, some honest souls take 12.
All of these are in the Pawty Marketplace, filtered to retailers that deliver to your country.
Pawty is educational content, not veterinary or behavioural advice. See a veterinarian for any sudden behaviour change or sign of pain, and a qualified behaviourist in person if your dog has bitten, guards with snapping, or panics when left alone. Read our approach.
Pawty also has 99 training skills in 3-minute sessions you rate 1 to 5 paws, streaks that freeze instead of reset, and a care calendar. Free. No subscription, no paywall.
