If you’re here because you’re trying to make one practical decision after losing your Portuguese Water Dog, I’m so sorry. This guide keeps urn sizing clear and steady—so you can choose a capacity that fits comfortably without second-guessing it.
Quick answer
- Sizing rule: plan for about 1 cubic inch per pound of body weight.
- Typical adult Portuguese Water Dog weight: about 35–60 lb.
- Minimum urn capacity: about 35–60 cubic inches.
- Comfort range (roomier fit): about 42–72 cubic inches (adds ~20%).
- Most Portuguese Water Dogs fit best in a Medium urn (25–60 cu in), but if your comfort estimate approaches 60 cu in (or your dog was closer to 55–60 lb), Large is usually the calmer choice.

The sizing rule (1 cubic inch per lb) and why we still size up
Urn capacity is measured in cubic inches. A practical starting point is one cubic inch of urn capacity for each pound of your dog’s weight. Many families choose a little more than the minimum because it helps the inner bag settle more easily, makes closure feel calmer, and leaves breathing room if weight is an estimate.

Portuguese Water Dog 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 number—especially if you’re close to a cutoff like 60 cubic inches.
| Your dog’s weight | Minimum capacity (1:1) | Comfort capacity (add ~20%) | Usually a good fit in |
|---|---|---|---|
| 35 lb | 35 cu in | 42 cu in | Medium |
| 40 lb | 40 cu in | 48 cu in | Medium |
| 45 lb | 45 cu in | 54 cu in | Medium |
| 50 lb | 50 cu in | 60 cu in | Large (often the calmer choice) |
| 55 lb (upper-boundary) | 55 cu in | 66 cu in | Large (calmer fit) |
| 60 lb (upper end / boundary) | 60 cu in | 72 cu in | Large |
Which Funeral.com size category fits most Portuguese Water Dogs?
Many Portuguese Water Dogs fit well in a Medium pet urn (25–60 cubic inches), especially smaller adults. The decision point is the top of the Medium range: if your comfort estimate approaches 60 cubic inches (common around a 50 lb dog), Large is often the calmer choice because it avoids a tight fit and makes closure easier.
Tip: Shop by the urn’s listed capacity. Some designs (especially photo urns or memory-box styles with compartments) can have less usable interior space than they appear to from the outside.
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 Portuguese Water Dogs, “close to the top” often shows up at the 60 cu in cutoff. If your comfort estimate approaches 60, choosing Large 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.
