By Teddy started when founders Delphi and David were preparing for their puppy, Theodore, and couldn't find dog products that fit naturally into the way they wanted to live. The London-designed collection now spans travel, walk, wear, and home, with functionality built into the details rather than added as an afterthought. Think carriers with laptop storage and settle mats, coordinated walk sets, practical drying layers, and colors designed to work together. At Bisou Dog, that's what makes By Teddy interesting: the products aren't designed around leaving the dog at home. They're designed around making room for them in the life you already have.
