These pet urns are made to order. The large are roughly 7" high and 6" across for 40 to 50 lb animals, the small are 5.5" high and 4" across for 10 - 20 lb animals.   Betsy can write a name and date on the bottom of the urn before the glaze firing.  If you would like this, add it to the comment section when ordering.  If you have any questions, do not hesitate to e-mail or call us at 888 737 4014.  We can also do custom sizes.
