A pet subscription box is a printed corrugated mailer sized to a monthly set of treats, a toy or two, and a chew, built to survive a parcel network and then a dog, and printed to look good in the unboxing video. We make them as roll end tuck front mailers in E or B flute, printed inside and out, with a paperboard insert or a divider that keeps treat bags from crushing toys, in any size and with no minimum order. The number that decides the box is the heaviest item: a monthly box with a bully stick, a bag of treats and a plush toy is usually 1 to 2 pounds and needs 32 ECT board; add a rubber chew or a two pound bag of food and it moves to B flute and 44 ECT.
Subscribers buy the ritual as much as the contents. The box gets opened on the floor, on camera, with the dog in the frame. So the print has to read from a distance, the lid has to open toward the camera, and the structure has to hold up when a paw lands on it.
Sizing from the set
Start with the item list for a typical month and the two heaviest items. Toys set the depth, treat bags set the footprint, and the total weight sets the board.
| Typical month | Weight | Mailer that fits (inside) | Board |
|---|---|---|---|
| small dog or cat: 2 treat bags, 1 small toy, a card | under 1 lb | 9 x 6 x 3 in | E flute, 32 ECT |
| medium dog: 2 treat bags, plush toy, chew | 1 to 2 lb | 11 x 8 x 4 in | E flute, 32 ECT |
| large dog: 2 treat bags, rope toy, rubber chew, bully stick | 2 to 3.5 lb | 12 x 9 x 4 in | B flute, 32 or 44 ECT |
| deluxe: toys, treats, a 2 lb food sample, a bandana | 3.5 to 5 lb | 14 x 10 x 5 in | B flute, 44 ECT |
| cat: treats, wand toy, catnip, a small blanket | under 1.5 lb | 10 x 8 x 3 in | E flute, 32 ECT |
All of these stay under one cubic foot, which keeps parcel billing on actual weight rather than volume. If the deluxe box grows past 14 by 10 by 6 it crosses that line and every shipment costs more.
Structure and inserts
The roll end tuck front mailer is the right structure for nearly every pet box: it ships flat, folds without tape, locks with front tabs, has double walls on the long sides for crush strength, and opens like a lid. Inside, a simple paperboard divider keeps a hard chew from crushing a treat bag, and a die-cut insert holds a toy in place for the reveal. Tissue in the brand color and a printed card on top finish it. Avoid loose fill; it ends up on the floor and in the dog.
Board, print and the dog test
E flute prints the finest detail and suits boxes under 2 pounds. B flute is thicker and takes a bite or a paw better, and it is the right call once a rubber chew or a bag of food goes in. Print full color inside and out; the inside lid is what the camera sees first. A matte aqueous coating resists scuffing in transit and does not flake. We send a sample so you can pack a real month, drop it, and let the dog at it before you commit.
Changing the box each month
Keep one dieline and change the artwork. Seasonal themes, a birthday box, a puppy starter box: same structure, new print, a run matched to that month’s subscriber count. No minimum order means a hundred boxes for a launch cohort is a normal order, and reorders run from the approved file without repeating the setup.
In short
What to send us: a typical month’s item list, the two heaviest items, the subscriber count, and the pet size the box is for. What you get back: a mailer sized to the set and under one cubic foot, board matched to the weight, an insert or divider spec, a dieline you keep, and a physical sample. What it costs you to start: nothing. Free design, free dieline, free samples, no minimum order.
Pet subscription box questions
What size box does a dog subscription need?
For a medium dog, 11 by 8 by 4 inches inside holds two treat bags, a plush toy and a chew. Small dog and cat boxes run 9 by 6 by 3; large dog boxes 12 by 9 by 4. Size from the two heaviest items and keep the total under one cubic foot so shipping is billed on actual weight.
What board should a pet box use?
E flute at 32 ECT for boxes under 2 pounds. B flute, 32 or 44 ECT, once a rubber chew, a bully stick or a bag of food goes in, because it takes a paw and a bite better and holds the weight in the parcel network.
How do I keep treats from getting crushed by toys?
A paperboard divider between the hard items and the soft ones, or a die-cut insert that holds the toy in a cut-out. Loose fill does not work; it ends up on the floor and in the dog.
Can the box change every month?
Yes. Keep the structure and the dieline, change the artwork. Seasonal, birthday and puppy boxes all run on the same template with a run matched to that month’s subscriber count.
Is there a minimum order?
No. A hundred boxes for a launch cohort or five thousand for a mature list. Free structural design and dieline, free samples, and a printed proof before the run.
No minimum order. One or a full run. Free design and dieline, and a printed proof before production. Free samples so you can pack a real month and let the dog test it before you commit. Price match: send a written quote for the same size, board, print and quantity and we will beat it.
