About our Garments

Dog T-Shirts

Our dog shirts are made with high-quality 100% cotton that matches the quality you would expect from a human t-shirt. These shirts are perfect for your furry friends as they are breathable and durable, providing comfort and style. They will not only keep your dog clean but also add a fun style to their look.

Dog Hoodies

Our dog hoodies are made with high-quality, 100% heavy-duty cotton, providing warmth and durability during colder months. They feature a back-facing pouch pocket and a hood with a matching drawstring, making them stylish and functional. Hoodies are NOT pre-shrunk.

Dog Apparel Care

Caring for your dog’s hoodies and t-shirts is very simple. We recommend the same care instructions for human apparel: machine wash with cold water inside out, and tumble dry on low heat or hang to dry. We recommend using pet-friendly detergents- all natural, no dyes, no perfumes, and refraining from using fabric softeners to avoid coat and skin issues with your pet.

We value your unique needs and preferences, and we understand that you may not always find the size or style you’re looking for. If this is the case, we invite you to reach out to us via email, providing us with your specific requirements. Our team is committed to working diligently to source the products that meet your expectations and needs. Thank you for considering us as your preferred provider.

Human T-Shirts

We print on Gildan Softstyle unisex shirts, which are lightweight and provide year-round comfort. These shirts are preshrunk and made with premium ultra-soft ring-spun cotton, ensuring high quality and durability.  T-Shirts are pre-shrunk.

Human Hoodies

We print on Gildan 18500 unisex series hoodie sweatshirts made with a heavy blend ™ of 50/50 cotton and polyester material. These sweatshirts are perfect for keeping you warm during the colder months, and they feature a front pouch pocket, a soft fleece-lined hood, and double stitching along the seams for enhanced durability.

Human Apparel Care

We recommend machine washing your garment inside out in cold water and either tumble drying on low heat or hanging to dry to minimize the risk of shrinking and preserving the print.
