We’ve brought you lots of stories about all sorts of unlikely animal friendships: Elephant dotes on dog. Deer protects goose. Puppy plays with pony. But today’s story, which comes to us from the U.K.’s Daily Mail, takes things to a whole new level. Not only is Jack the sheep best friends with a sheepdog—he thinks he is one!

Watch below to learn the story of Jack, a lamb who was born on a farm and raised alongside his owners’ springer spaniel named Jesse. Just like his canine brother, Jack loves to chase sticks and go for walks on a leash. He even helps out when it’s time to herd the other sheep!

Brace yourselves, folks: Here comes yet another adorable video of an unlikely friendship in the animal kingdom! This time we’re celebrating the bond between Herbie the pit bull puppy and Jabby the horse.

Jabby seems happy to have a playful visitor at the stable, and clearly Herbie is ecstatic at having made such an enormous friend! I didn’t think anything could even come close to “too cute” until I got about 20 seconds in to this video. A horse and a puppy—snuggling! It’s puppy love indeed.

While her owner, Cassie Murdoch, lays out photos and writes captions for next year’s DOG Gallery Calendar, Eloise, a petite Cavalier King Charles Spaniel, lends a paw. Maybe next year we’ll even give Eloise a writing credit!
