Old English Sheepdog Considerations
This is a "Velcro" breed in the truest sense. They were bred to work closely with shepherds and drovers, never straying far. In a modern home, this translates to a dog that may panic when left alone. Destructive chewing, howling, and house soiling are common symptoms of distress if isolation training is not started immediately in puppyhood.
The OES has a unique, ringing bark often described as "two pots clanging together." It is loud, deep, and can become a nuisance. They are alert watchdogs and will vocalize at delivery trucks, neighbors, and squirrels. This makes them poor candidates for apartments with noise restrictions.
As a drover's dog, the OES controls movement. In a family setting, this often manifests as nipping at the heels of running children or "body checking" people to move them. While not aggressive, this behavior can be frightening for toddlers and annoying for guests.
While generally social, some OES lines—particularly males—can develop aggression toward other dogs of the same sex around social maturity (18-24 months). This requires vigilant management in multi-dog households.
