The question is grammatically incorrect and nonsensical. It is likely intended to ask which dog breed is considered the least intelligent, according to some ranking system. Therefore, a reasonable interpretation of the prompt is, "According to the 'The Intelligence of Dogs' ranking, which breed would be considered the least intelligent based on trainability and working intelligence?"
The provided reference focuses on the most intelligent dog breeds according to Stanley Coren's research and ranking, as presented in The Intelligence of Dogs. It lists the top breeds but does not include information about the least intelligent. Therefore, based solely on the provided information, it is impossible to answer which dog has the lowest IQ or is considered the least intelligent. However, we can say which dogs are considered among the most intelligent.
According to the The Intelligence of Dogs rankings, the top four most intelligent breeds are:
| Rank | Breed |
|---|---|
| 1 | Border Collie |
| 2 | Poodle |
| 3 | German Shepherd |
| 4 | Golden Retriever |
It's important to note that judging "intelligence" in dogs is complex, and Coren's rankings primarily focus on obedience and working intelligence (i.e., how quickly and easily a dog learns and obeys commands). Other measures of intelligence, like problem-solving abilities or adaptability, might yield different results.
