Small keepsake jewelry made to hold a bit of ash or fur, a quiet way to carry a pet's memory with you every day.
Capacity is deliberately tiny, a pinch rather than a portion, so plan on a pet urn as well if you are keeping all of your dog or cat's ashes. Size that urn at roughly one cubic inch per pound of body weight, which means about 45 cu in for a 45 lb dog. Fur works as well as ash in these pieces and is a good deal easier to handle. A jeweler can seal the threads with adhesive if you would rather it never opened again.
