Small dog urns: a size chart by weight

Small dogs often leave the biggest hole in a home. If you're choosing an urn for a small companion, the main question is size: an urn that's slightly too large is fine, but one that's too small won't hold all of the ashes. This guide makes sizing simple.

The sizing rule

Allow about one cubic inch of urn capacity for every pound of your dog's healthy weight. Use their weight when they were well, not after an illness, and round up.

Small dog urn size chart

Dog's weight	Example breeds	Urn capacity to look for
Up to 10 lb	Chihuahua, Yorkshire Terrier, Pomeranian	10–15 cubic inches
10–20 lb	Shih Tzu, Pug, Miniature Dachshund	20–25 cubic inches
20–30 lb	Beagle, French Bulldog, Cocker Spaniel	30–40 cubic inches

Breed weights vary, so use your own dog's weight rather than the breed average. Each urn's capacity is listed on its product page. See small pet urns.

Adding a collar, tag or keepsake

Many families like to place a collar, tag or a small note inside the urn. If you'd like to, choose an urn with 10–20% more capacity than your dog's weight, or keep the collar beside the urn instead.

Choosing a material

Natural marble is a popular choice for small dogs because it's substantial and lasting even in a small size, and every piece has its own veining. See marble pet urns. If you'd like to keep a portion of your dog's ashes in more than one place, a keepsake urn holds a small amount.

Sharing ashes among family

If more than one person would like to keep part of your dog's ashes, choose one main urn plus a keepsake for each person. Because a small dog's ashes are a modest amount, check the main urn still has enough room for what remains.
