Klondike, Toy American Eskimo.
Klondike and Sundae are Jack and Erin's current dogs, both of which are Toy American Eskimo. In YGS #60, Jack claimed Klondike was three months old, so she was born in August of 2013, and in August she will be five years old. Sundae is likely somewhere between eight and eleven months old. Klondike makes regular appearances on Jacksfilms, appearing in JackAsk, GamerGod88, YIAY, Your Grammar Sucks and other.
Sundae, Toy American Eskimo.
Sundae makes regular appearances on Jacksfilms as well, appearing in PMS, YIAY, Your Grammar Sucks, JackAsk and other. She made her debut appearance in WINTER in 4 WORDS (YIAY #230), where fans tried to figure her out a name, but Jack revealed he already named her from the treat Sundae, similarly to how he named Klondike from the Klondike Bar.
They appear in an episode called "$10,000 DOG VS. $1 DOG"; where they are compared with one another in their comprehension of jacks commands or skills such as fetching. In this episode, Klondike is shown as more alert and/or obedient.
In YIAY 501, Jacksfilms announced that he has another puppy, which he named Chipwich.
