Tuesday, February 20 marks national #LoveYourPetDay, and social media is abuzz with photos of kittens, puppies and more.

Carlin, 8 weeks, he's bigger now.

Sure, you could argue that every day is a day to love your pets, but it’s always nice to have a reason to share photos of your loved ones on Twitter, Facebook and Instagram.

Like this gives us a chance to repost this picture of Carlin, the unofficial mascot of SensiblePets. Carlin is a Staffordshire Terrier (aka pit bull) and he’s about three years old.

Even though there’s plenty of photos of him as a grownup, it’s an excuse to put up this picture with the pound puppy eyes. Look at that expressive brow.

At any rate, we know Carlin is a purebred Staffy thanks to the good folks at Wisdom Panel. A few weeks ago the test results came back that our boy is a full-blooded pit bull. I mean, you can tell by looking at him that he’s clearly a pit, but there was always some internal discussion about the potential for other breeds mixed in.

I was convinced there was some Shar Pei in there. Nope. Just American Staffordshire.

The purebred genes probably explain why he has some knee problems. After all, Carlin has had surgery on both of his back knees. He’s on the mend though, and looking forward to playing with his girlfriend, Darby. Seen below.
