Pal is Arthur Read's pet dog. He is voiced by Simon Peacock.
In "Arthur's Pet Business", Arthur watched many animals including Mrs. Wood's dog, Perky. Mrs. Wood had a list that he needed to abide by for Perky to be happy, such as brushing her 100 times. When Mrs. Wood was about to pick up Perky Arthur believed that he had lost her, but she was actually giving birth to be a litter of puppies behind one of The Reads' chairs. Mrs. Wood lets Arthur pick Pal out of the litter because he was a good petsitter.
Pal is a small golden-haired dog with smooth fur. When he was first born, he had fuzzy fur. He wears a red collar with a silver pendant attached to it. In the TV series and CGI movie, his eyes are black; although in the books and in many detailed illustrations, they're normally white with a black dot in each one, but he is occasionally seen with black eyes.
In some episodes, it's shown that Pal can communicate with other animals and human babies. In these episodes, he speaks with a high-brow British accent and acts sophisticated. He likes to sleep under the couch, but he usually loves to sleep on Arthur's bed with him and comforts him by licking him after he has a nightmare. He dislikes being alone in places.
When he was a couple of weeks old, he was easily excited and not housetrained. He bit his leash and popped the tire of Francine's bike with his teeth. Because of doing these things Arthur's parents gave him the options that Pal will either stay in the garage or be sent away until he was housetrained, both of which were to Arthur's objections. However, Arthur spent a lot of time training him and he has since then learned to become a fairly-intelligent dog. He only knows basic tricks, such as sit, and Arthur failed to teach him more complex orders.
