Dogs should not be tethered or chained, except for very short periods, as restraining a dog in this way can lead to injuries and also restrict normal behaviour, which can be very damaging to the dog's wellbeing. Don't let your dog become lonely or bored, and never leave them alone long enough to become distressed. Signs of a distressed dog included barking, howling or whining excessively, as well as panting, hiding and/or showing aggression. Making sure your dog has appropriate company is an important consideration for outdoor dogs. Social needs - always make sure your dog is able to behave normally and is provided with the opportunity for daily exercise, play and interaction with animals and people. Most dogs cope well living outside if they have proper shelter, water, and protection from extreme weather. A dog's physical, social and behavioural needs are very complex, and meeting these needs can be very hard, if not impossible, for dogs living outside.
