He finally stopped escaping when Mr. Sg put up an electrified fence and put one of those collars on him. He eventually became too old to easily jump the fence, but he'd deliberately wear out the battery on the collar by sitting as close to the fence as he could stand it. Smart, tough doggie.
They are loyal, intelligent, affectionate and brave. We have a six foot, chain link fence around part of our yard. This is a good description of the breed:
Temperament
Rhodesian Ridgebacks are loyal, intelligent, and somewhat aloof to strangers. This is not to be confused with aggression; a Ridgeback of proper temperament will be more inclined to ignore, rather than challenge, a stranger. This breed requires positive, reward-based training, good socialization and consistency; it is often not the best choice for inexperienced dog owners. Ridgebacks are strong-willed, intelligent, and many seem to have a penchant for mischief, though loving. They are protective of their owners and families. If trained well, they can be excellent guard dogs. Like any dog, they can become aggressive when they are not socialized properly.
Despite their athletic, sometimes imposing, exterior, the Ridgeback has a sensitive side. Francis R. Barnes, who wrote the first standard in 1922, acknowledged that “rough treatment ... should never be administered to these dogs, especially when they are young. They go to pieces with handling of that kind.”[9] The Ridgeback accepts correction as long as it is fair and justified[citation needed], and as long as it comes from someone he knows and trusts.
