    We just received the harness and leash set and it is perfect! We’ve had a hard time finding a harness to fit our 14lb senior dog and this harness fits perfectly - like it was made for him! Great quality and super cute design.

    We practically shop every new set of harness and leash from B&B whenever it comes out. The last three sets we bought were burgers, sea creatures and cupcakes. We love them and get lots of compliments at parks and our doggie daycare.

    My order got delivered really fast! I’ve bought harnesses for my dogs from a few other brands but these are by far my favorite. The quality is great and there were so many pattern options. I’ve got compliments on them already! Will definitely be ordering from them again

    We love it!!

    Fits perfect! Looks super cute on him! My dog loves to slip out of his harness even when I’ve bought him XS in other brands. He cannot escape from this one and its great! Great quality!

    Excellent!!!! The print is beautiful and the fit is perfect!!!! This is my 5th harness from Beast and Buckle and I love every one of them. The quality is excellent and free shipping and extremely fast delivery! I highly recommend this brand to everyone I know. Even my dog Khaleesi was so excited when I showed her the package she was going nuts to open it. It was like she knew it was for her, lol I would give higher than 5 stars if it was a choice. ❤️
