Best Friends Rainbow Pet Tank

Let your pup or kitty twin with you in the sweetest way possible with our Rainbow Best Friends Pet Tank, made to match our human Best Friends rainbow collection. Bright, bold, and full of love, this tee lets the world know your true BFF walks on four paws.

Crafted from soft, breathable fabric for all-day comfort, it’s perfect for dogs or cats who love attention (and snuggles). Featuring a playful rainbow design that pairs perfectly with your matching piece, this shirt is made for adventures, couch hangs, and every heart-filled moment in between.

Because pets aren’t just pets. They're family. They're healers. They're home.

And because we believe in giving back, a portion of every purchase from this collection goes directly to Best Friends Animal Sanctuary, helping more animals find love, safety, and the freedom they deserve.

Using the Pet Tank Size Chart to Measure Your Pet: 

Length: Measurement of the pet’s back from neckline to tail end. 
Width: Measurement around the largest part of your pet's rib cage. (Usually is similar to our graphic shown on the listing) 
Collar: Measurement from the back to the front of the neck. It is not the full circumference, just half.
