Small, deliberate urine deposits on vertical spots, communication, not emptying. More common in intact males and in multi-dog homes.
Marking responds well to the supervise-clean-redirect triangle. Neutering reduces it in many but not all males, discuss timing with your vet.
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.
