How often should I test my dog's IQ?

You should not test your dog's IQ with formal, standardized tests, as these are not widely available or scientifically validated for canine intelligence in the same way human IQ tests are. Most "dog IQ tests" found online or in books are informal assessments of trainability and problem-solving skills, not a measure of innate intelligence. Instead of frequent testing, focus on consistent training and enrichment to stimulate your dog's cognitive abilities.
