Loved by dog owners

Charlotte M.

The harness quality is really good. Everyone who has noticed it has praised both the quality and how beautiful it looks. It is comfortable, durable, and very effective for daily walks. I absolutely recommend Castellar Collars and Olesia to anyone looking for outstanding craftsmanship and premium leather products for their dog.

David C.

Absolutely worth every penny. It fits my 15-month-old Rottweiler perfectly, with plenty of room to grow thanks to the adjustable buckles. The leather and craftsmanship are outstanding, and the harness feels incredibly durable. I couldn't be happier with my purchase and would 100% recommend this harness to every dog owner.

Sophia L.

I bought a beautiful dog harness for my Leonberger two years ago, and it's still the finest leather harness I've ever owned. I recently received a bespoke leash, and once again the craftsmanship is amazing. Olesia is incredibly friendly and helpful, and every product is made with exceptional care. I will definitely order more beautiful items when my new puppy arrives.

Jessica W.

I absolutely love this harness! The leather is thick, buttery soft, and incredibly high quality. The stitching is phenomenal, and it fits my dog perfectly. It exceeded all my expectations and is exactly what I was looking for. I know we'll receive so many compliments, and I'll definitely recommend your shop to everyone I know.

My lad Silverthorne's Majestic, aka Ozzie, is my mobility service companion, so I needed a strong handled collar I could truly rely on. Having "MAJESTIC" embroidered on the handle is such a thoughtful touch. The soft padded lining is incredibly comfortable for Ozzie's neck and really makes the collar feel like a premium piece. It is absolutely worth the money, and the craftsmanship exceeded my expectations!

We are very happy with the customer service and quality of the item. This is our second dog halter because I lost the first one in a move. It works wonders for my 2 year old German malamute who loves to pull and walk on hind legs like a Looney tune. With this he walks right beside me and every turn with minimal corrections. Thank you so much again!!!! 🙏😌

The head harness was purchased to walk our Tibetan Mastiff because he is so large it is the only thing we could buy to control him. Quality is brilliant and it fits perfectly and is comfortable. I strongly recommend anyone buy this for their dogs, especially if it is large.

Ava P.

Our family is completely satisfied and amazed at the quality of craftsmanship put into Diamonds collar. We are proud to show it off to everyone we know. Thank you so very much for all your professional work.

The collar is of excellent quality and masterfully crafted. It suits my large Kangal dog wonderfully. The leather feels incredibly durable, yet soft and comfortable for everyday use. I wholeheartedly recommend it for any potential buyer!

Olivia K.

Jelly Bean’s new collar arrived today and I couldn’t be happier! It is beautifully made, the colors are gorgeous, and the quality is outstanding. The handmade details make it feel really special. It fits her perfectly and looks so pretty against her gray coat. Thank you for creating such a lovely collar—we both love it!
