While a stimulating multi-dog environment can offer cognitive benefits, the quality of interaction and the individual dog's inherent intelligence are more significant factors than sheer numbers. For instance, Border Collies consistently rank among the most intelligent breeds, often demonstrating a capacity to learn over 200 words, regardless of their pack size. Ultimately, a dog's intelligence is a complex interplay of genetics, environment, and training. Discover how to maximize your dog's intellectual potential in our complete guide.
