I have a friend who often wishes she could train her cat to run errands and do chores — start the coffee, grab the paper, maybe run a load of laundry. Turns out, this helpful little pet already exists, in the form of a peppy Jack Russell Terrier named Jesse! Jesse may just be the most helpful pup ever, but what cracks me up is how cheerfully he performs his chores. Check out Jesse in action, and spend the weekend wishing for your own errand dog!

Seven-year-old Chaser, a Border Collie in North Carolina, knows how to sit, stay, and fetch. Big deal, right? Until you hear this: she can also recognize and respond to over 1,000 other words.

Chaser's owner, John Pilley, is a college professor — with a ton of patience. After hearing of another pup who'd been taught over 200 words by his master, Pilley decided he could do better, so he set to work training Chaser when she was still a puppy. After years of learning one or two new words a day, Chaser can now recognize hundreds of toys by name (that pooch must have some toy box!). She can also correctly follow commands like "Fetch a ball" and "Fetch a Frisbee."

Next up, Pilley's going to attempt to teach Chaser basic grammar. Does this inspire you to expand your pet's vocab?

Or, at least, a couple thousand Facebook fans! This adorable baby dolphin at the Minnesota Zoo has been having an identity crisis since her birth in July, but luckily, the zoo’s Facebook fans stepped in and submitted their votes to give the bottlenose calf a name. Taijah, the winning name with 37 percent of the votes, is four feet long and 60 pounds — some baby! — and the zoo describes her as "spunky, inquisitive, bold, and sassy."

Check out more photos of Taijah after the break!
