It’s Monday morning—woof. Instead of worrying about the week ahead, watch this video of a boxer puppy meeting some cows! It’s sure to melt your heart (and your anxieties).

For more charming stories of unusual animal pairings, pick up a copy of Unlikely Friendships by Jennifer S. Holland.

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.

By now you’ve probably seen that adorable video of the sleepy cat pulling her kitten into a hug. (You haven’t?! OMG watch it right now!!) Yeah, that video is absurdly precious. But you know what’s even cuter than mom-on-baby loving? Interspecies loving!

Can you imagine anything sweeter than a dog who just wants to be BFFs with some dolphins? (Also watch that video. You won’t regret it.) Jennifer S. Holland’s new book Unlikely Friendships details forty-seven remarkable stories just like that: true tales of all sorts of critters breaking the bounds of their species and forging the unlikeliest of bonds. Like the snoozing kitties, this book is beyond adorable—it’s amazing. Here’s a first-person account from Workman employee Craig, who saw with his own eyes how the book’s cuteness can make people positively squeeeee with delight.

Jennifer Holland’s Unlikely Friendships will melt the heart of everyone who picks it up. Case in point: I get home from work a couple of days ago and my wife Tanya and ten-year-old daughter Maddie are going at it like two screaming harpies. It’s over homework, long division to be specific, and Maddie’s to the point of tears, claiming that mom doesn’t know anything, and, “That’s not how Ms. Lesiner taught me how to do it!” At this point, I’m thinking about a quick retreat, but the two she-devils spot me and so I approach them cautiously and say, “Hey, check out this book that just rolled off press.”

I place the copy of Unlikely Friendships in front of them, quickly step back to avoid losing a limb, and then watched the most amazing transformation take place. Their faces softened as they slowly flipped through the pages, they leaned into each other as Tanya read the story of the Macaque and the Kitten, and the banshee-pitched screams that first greeted me when I walked into the house miraculously subsided into angelic whispers of delight. My two girls moved over to the couch and there the two of them remained for the next two hours reveling in the magic of this absolutely moving book. As a result, I ended up having a bowl of cereal for dinner by myself, the math homework never got done, and now Maddie wants a baby orangutan for a playmate for our dog.

Unlikely Friendships goes on sale July 1, and is available for pre-order now.
