Having owned both, cats never seemed all that bright to me. I can understand liking them better than dogs as animals or pets, but saying they’re more intelligent than dogs seems absurd.
I agree. I have trained a lot of dogs from protection/bitework to bird dogs (English pointers) and hounds. There are a lot of dogs that have a spoken vocabulary in the hundreds. Cats, just one, the call to the food bowl.
Dogs are capable of leaning to perform myriad tasks and jobs.
