The RSPCA recommends that you do not leave your dog alone for more than four hours, and for puppies much less. If you need to be away longer, it suggests a dog sitter or dog walker who can keep your dog company and take them for a walk. See how long a puppy can hold its bladder.

The ASPCA describes a training milestone: once a dog can be alone for 90 minutes without getting upset or anxious, he can probably handle four to eight hours, and it suggests trying four hours first and working up over a few days. Guidance differs between organizations, so treat this as a milestone in training, not a daily target, and consider your dog’s age, health, and needs.
