Various dogs appear throughout the series, usually playing a minor role and sometimes causing the deaths of characters. Some are shown to be pets while others are apparently strays.
- Main article: Whistle
Puppies or dogs that resemble Whistle have appeared in a few other episodes. Some appear at the end of Doggone It, being released from Lifty and Shifty's van before tearing Lumpy to shreds, along with the original Whistle. Another pup appears in Junk in the Trunk as yet another thievery victim of Lifty and Shifty. A yellow puppy in A Sight for Sore Eyes served as The Mole's seeing-eye-dog, but it ran off chasing Sniffles' mechanical paper plane. A purple dog that appears in Chore Loser acted very similar to Whistle as it killed Cub (and possibly Pop).
This dog makes a small appearance at the beginning of Doggone It. It is shown growling and trying to burst out of its metal cage, surrounded by dents on the wall and torn-up toys. Cub wanted it, but Pop decided just to purchase Whistle from the pet store instead.
In Easy Comb, Easy Go, Lifty and Shifty tested one of their hair growth formulas on a small hairless male dog. He grew a luxurious coat of hair, attracting the attention of a female. This prompted Disco Bear to purchase the hair growth formulas for himself.
In Clause For Concern, these dogs were attracted to the scent coming from sausages inside a sack in Pop's trunk. One dog wearing a spiked collar seemed to resemble a doberman. Another was a small puppy (or possibly a chihuahua). A shaggy sheepdog and a tall greyhound-like dog also appeared. The dog wearing the spiked collar was later seen at the mall, appearing out of nowhere and taking a bite out of the sausages.
This large shaggy dog appears in Put Your Back Into It. It went to fetch a bone tossed near Disco Bear, biting his spine and thrashing him about. Then it bites on Disco Bear's leg as Russell unknowingly reels him in, which leads to Disco Bear's head and spine being torn off, killing him.
If one looks closely in Remains to be Seen, this small dog can be seen behind a tree when the zombified Handy, Toothy, Mime and Generic Tree Friends appear. It is unknown why it is here, being a hidden Easter egg like The Cursed Idol, which also appeared in this episode.
Appears as one of the obstacles in the Park level of Run and Bun, attacking a character if he/she bumps into it.
