Do these intelligence differences apply to all dog breeds?

No, intelligence differences do not apply equally to all dog breeds. Border Collies consistently rank as the most intelligent dog breed, often compared to a human toddler with an IQ of 60-70. Poodles also rank highly, typically within the top five. In contrast, breeds like the Afghan Hound are consistently ranked among the least intelligent, often requiring 80-100 repetitions to learn new commands. These significant variations highlight that intelligence is not uniformly distributed across the canine kingdom.
