I picked up this toothbrush from Pure and Natural Pet because clean ingredients matter, especially for something that goes in your dog's mouth a few times a week. The brand keeps their materials simple and non-toxic, and the bamboo handle is fully biodegradable when you replace it. They also partner with rePurpose Global to recover plastic from the environment with every purchase, so each one does a little good beyond your own bathroom counter. It is a small swap from the plastic brush you have probably been using, and exactly the kind of clean, well-made product I want on the shelves at The Dog Shoppe. ~Bradley
