Any dog breed can be aggressive if it hasn’t been trained or treated properly. Rhodesian Ridgebacks aren’t generally aggressive dogs, but this cannot be said for every dog in the breed.
Historically, Ridgebacks were bred to be hunting dogs. This means that they are naturally territorial and protective dogs, however, this does not translate into aggression.
Instead, they are generally well-mannered and even-tempered, making them a great breed for families with or without kids.
While they were bred for hunting and have excellent predatory instincts, Ridgebacks are fairly gentle and sensitive dogs that aren’t usually aggressive or loud.
They are extremely intelligent, which means that they might be able to suspect an intruder or bad energy from a person, where they might become somewhat aggressive. However, this is only due to their territorial nature.
In short – no, Ridgebacks aren’t aggressive. It all depends on how the dog has been trained and treated. Despite their hunting background, Ridgebacks are tender and gentle dogs who are highly protective over their companions.
