Dogs are social animals, being alone is a learned skill, not a factory setting.
Mild alone-time trouble is common and trainable. True separation anxiety exists too, if the video shows panic, a certified trainer or vet behaviourist is the right call, and asking for help is good ownership.
All of these are in the Pawty Marketplace, filtered to retailers that deliver to your country.
This one is safety-critical or emotion-driven. Work with a qualified force-free trainer or a veterinary behaviourist rather than doing it alone. 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.
