If you’re here because you’re trying to make one practical decision after losing your Cocker Spaniel, I’m so sorry. This guide keeps urn sizing simple and steady—so you can choose a size that fits comfortably without second-guessing it.
Quick answer
- Sizing rule: plan for about 1 cubic inch per pound of body weight.
- Typical adult Cocker Spaniel weight: about 20–30 lb.
- Minimum urn capacity: about 20–30 cubic inches.
- Comfort range (roomier fit): about 24–36 cubic inches (adds ~20%).
- Most Cocker Spaniels fit best in Medium because this breed sits right near the 25 cu in cutoff where “Small” can feel tight.
Start shopping here: Pet Urns for Dogs. For Cocker Spaniels, compare: Small Pet Urns (under 25 cu in) and Medium Pet Urns (25–60 cu in).
The sizing rule (1 cubic inch per lb) and why we still size up
Urn capacity is measured in cubic inches. A widely used starting point is one cubic inch of urn capacity for each pound of your dog’s weight. Many families still choose a little more than the minimum because it makes the inner bag easier to settle and the closure feel calmer—especially when your dog’s weight is an estimate or you’re close to a size cutoff.

Cocker Spaniel weight to urn capacity (cubic inches)
If you have a recent vet record, use that number. If not, use your best estimate and lean toward the comfort range—especially if your Cocker Spaniel was sturdy, overweight, or a mix.
| Your dog’s weight | Minimum capacity (1:1) | Comfort capacity (add ~20%) | Usually a good fit in |
|---|---|---|---|
| 20 lb | 20 cu in | 24 cu in | Medium (often calmer) or Small (only if the listed capacity is clearly enough) |
| 25 lb (borderline) | 25 cu in | 30 cu in | Medium (recommended) |
| 30 lb | 30 cu in | 36 cu in | Medium |
| 35 lb (larger / mix / overweight) | 35 cu in | 42 cu in | Medium (roomier end of the range) |
Which Funeral.com size category fits most Cocker Spaniels?
Most Cocker Spaniels fit best in a Medium pet urn (25–60 cubic inches). The reason is simple: many Cockers land right around 25 lb, and “Small” urns are typically designed for capacities under 25 cubic inches. If you want the easiest closure with the inner bag (and less worry about a tight fit), Medium is usually the calmer choice.
- Shop Medium Pet Urns (25–60 cu in)
- Shop Small Pet Urns (under 25 cu in) (often best for pets under ~20 lb or a portion of ashes)

Size up if… (a simple rule that prevents a tight fit)
Size up if your dog’s weight is an estimate, your dog is a mix, your dog is big-framed or very muscular, you want room for mementos (tag, note, fur clipping), or you want the easiest closure with the inner bag. If your dog’s weight is close to the top of this size tier, choosing the next tier up is usually the calmer choice because it avoids a tight fit.
For Cocker Spaniels, “close to the top” often shows up at the 25 cu in cutoff. If you’re near it, Medium usually removes the stress.
Sharing plan options (keepsakes and jewelry)
If more than one person wants a portion of ashes, a gentle plan is one primary urn plus keepsakes (or jewelry) so you don’t have to reopen the main urn repeatedly.

What size urn do I need for a Cocker Spaniel?
Most Cocker Spaniels are about 20–30 lb, so a typical minimum range is 20–30 cubic inches. For a calmer fit, many families choose about 24–36 cubic inches (adding ~20%).
What size urn do I need for a 20 lb Cocker Spaniel?
Start with 20 cubic inches minimum. For comfort, aim for about 24 cubic inches. If you want the easiest closure and less chance of a tight fit, Medium is often the calmer choice.
What size urn do I need for a 25 lb Cocker Spaniel?

Should I choose a Small or Medium urn for a Cocker Spaniel?
Most Cocker Spaniels do best in Medium (25–60 cu in). Small is typically under 25 cubic inches and can feel tight if your dog was near 25 lb or if you’re adding buffer for comfort.
How much extra capacity should I add beyond the minimum?
Many families add about 15–20% to the minimum estimate. This helps the inner bag settle comfortably and reduces the chance of a tight fit.
My Cocker Spaniel’s weight is an estimate. What should I do?
If weight is an estimate, choose extra capacity for comfort. If you’re between sizes, the larger option is usually the calmer choice.
Can I place a collar tag, note, or small memento in the urn?
Often, yes—just plan for it. If you want room for mementos, aim for your comfort target (or size up) so the fit doesn’t feel tight.
What if I’m splitting ashes between family members?
Consider one primary urn plus keepsakes or jewelry so you don’t have to reopen the main urn repeatedly. Keepsakes can make sharing feel simpler and more gentle.
How can I double-check the right capacity before ordering?
Use the Pet Urn Size Calculator, then choose an urn whose listed capacity meets or exceeds your comfort target. You can also compare with the Urn Size Chart & Complete Guide.
