Aidi
Also known as: Atlas Mountain Dog, Chien de l'Atlas, Kabyle Dog
The Aidi, also known as the Atlas Mountain Dog, is a primitive livestock guardian dog from Morocco's Atlas Mountains. This is not a 'pet' in the conventional sense - it's a working breed with retained hunting drive and intense territorial instincts. They were bred to guard nomadic camps from jackals and wolves, and to hunt alongside Sloughis.

Aidi Considerations
The Aidi views anything outside its family unit as a potential threat. This includes mail carriers, neighbors, and visiting children. Their default setting is suspicion, and they do not 'warm up' quickly.
High propensity for intolerance toward dogs of the same sex, emerging at social maturity (18-24 months). Can escalate to serious fighting if not managed with strict separation. A male Aidi with another male dog is a ticking time bomb.
As a survivalist breed from harsh environments, they may guard food, toys, or space with intensity. This is a genetic survival trait that makes them dangerous in households with toddlers.
They are not eager to please. If busy patrolling or investigating a scent, they will likely ignore you. They were bred to make autonomous decisions without human direction.
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.
Multi-Species Compatibility
| Species | Aidi | Old English Sheepdog |
|---|---|---|
| With Cats | Generally unsafe - high prey drive; may view running cats as prey to flush or grab | Generally safe with proper introduction |
| Small Mammals | Unsafe - birds, rabbits, and rodents trigger prey drive | Supervision required |
| Birds / Reptiles | Unsafe - birds fluttering trigger chase instinct | Caution advised |
Advanced Behavior
| Trait | Aidi | Old English Sheepdog |
|---|---|---|
| Predatory Sequence Risk | Full | Medium |
| Biddability | Low | Low |
| Noise Sensitivity | Low | Low |
| Territorial Barking | ||
| Same-Sex Aggression Onset | 18 months | 18 months |
Aidi: Full predatory sequence intact (Orient-Eye-Stalk-Chase-Grab-Kill). Their hunting history with Sloughis means chase and flush instincts remain. In absence of Sloughi to finish, they may complete kill sequence on small animals. They are intelligent problem solvers but do not look to humans for permission.

Aidi Quirks
The Side Eye
Aidis constantly watch and observe you - this is assessment, not aggression. They are always monitoring the environment.
Tactile Sensitivity
They show affection by leaning or sitting on your foot, but often dislike being hugged or restrained.
Metabolic Off-Switch
Like lions, they conserve energy until a threat appears. Not hyperactive pacers like Malinois.
