What size urn do I need?
Tell us roughly what they weighed and we will suggest a size that leaves a little room to spare.
Your pet
A rough weight is fine. If you only know a range, use the top of it.
How urn size is worked out
- About 1 cubic inch for each pound. That is the usual guide: a 10 kg (22 lb) dog needs about 22 cubic inches, roughly 0.36 litres.
- Use their healthy weight. If they lost weight towards the end, their usual weight gives a better guide.
- Between two sizes? Go up. Ash volume varies a little, and a bit of space is better than too little.
- Know the actual volume? If your crematorium gave you one, that beats any weight guide. Send it to us and we will check the fit.
What if I am sharing the ashes?
Some families keep a little in a keepsake and scatter or bury the rest. A keepsake urn only needs a small part of the ashes, so size it for the part you are keeping.
Is the largest size big enough?
Our largest urn is sized for pets up to 40 kg (about 88 lb). For a bigger dog, write to us and we will help you find the right option.
Breed weights: a starting point
These are PDSA breed averages, not your pet’s weight or a guarantee of urn fit. Use your pet’s usual weight in the calculator. If the crematorium has given you the volume of ashes, please share it with us so we can check the fit of the specific urn.
| Breed | PDSA average |
|---|---|
| Labrador retriever | 25–35 kg |
| Cocker spaniel | 13–14.5 kg |
| Staffordshire bull terrier | 11–17 kg |
| English springer spaniel | 18–23 kg |
| Border collie | 25–30 kg |
| Cockapoo | Varies; use your own dog’s weight |
Our personalised canopic urn has weight guides for pets up to 15 kg, 30 kg and 40 kg. These are guides, not measured ash volumes. For another urn, check that product’s own details or ask us about fit.
