Dogs think and they feel emotions and they have good days and bad days. They feel love and feel grief. They can be sneaky and silly and they can exhibit guilt. And they have a sense of humor, too.
Portuguese Water Dogs are well known for their sense of humor. We read and heard about it early in our Portie days. Bentley had a crazy sense of humor. He liked to play tricks on people and other dogs.
Tsar liked to play jokes on me. He had several but his and my favorite was one that he often played on dark moonless nights.
Last week my Portie girls started playing a joke on me. The four girls sleep in crates in the TV room at night. The first crate is Norma Jean's, next is Bailey's and Tess and Lola sleep together in an extra large crate. They've slept in the same crates since they were young pups. I leave the doors unlatched during the day and when we come in from last call, they each walk into their own crate and stand there till I give them their cookies and latch the crate doors.
No, you dumb "experts", you are very wrong. Dogs do think.
