the only question that matters

this morning i found fibre fill in kele's poop again.

it's from a plush toy i bought him last week. he's ten, a poodle mix, and he has never once been interested in a stuffed toy that is still stuffed. he wants it empty. he works until it's flat.

for a long time i told myself this was fine, because most of it turns up the next day and clearly nothing bad is happening.

that's not a safety record. that's a run of luck. i only worked out the difference after somebody left a comment.

the comment

be careful, they get those long strands stuck in their intestines. get rawhide.

a stranger taking the time to warn someone about a dog they've never met. i'd rather have that than another emoji.

they were also half right, and the half they got wrong is the more dangerous half. so this is worth doing properly — and it turned into a bigger question than i expected, which was: why is he doing this at all, and should i be stopping him?

the part i had backwards

i spent a morning last week seriously planning to pull every stuffed toy off this shop.

i'm glad i didn't.

taking a toy apart isn't a behaviour problem. it's one step in the predatory sequence — the run of behaviours a dog is built to perform, in order:

search → stalk → chase → grab → shake → tear → dissect → consume.

dissect is the step where, in a world without pet shops, a dog pulls the skin and fluff off the thing it caught. kele emptying a plush toy is that step running on a substitute.

and that need doesn't switch off when you remove the outlet. it relocates. what people describe after taking all the destructible toys away is frustration, restlessness, and destruction aimed at furniture, shoes and walls.

kele scratches at walls sometimes. i had been filing that as a separate problem.

so you don't get to solve destruction by removing toys. you only get to choose where it lands.

the sequence also explains the toy aisle

once you see the list, the shelves make more sense. most toys are just an offer to run one step of it.

a puzzle feeder is search. kele has one, and he has no interest whatsoever in the toy — only in getting the food out of it. that isn't him failing to play. that's him doing the first step and stopping, because that's the step he wants. there's decent evidence behind these: in shelter dogs, food puzzles reduce barking, pacing and repetitive licking, and slow down fast eaters.

a ball, a frisbee, a tug rope is chase and grab. this is where most dogs live, and most dogs are perfectly happy stopping here.

a hard chew is a slightly different thing — closer to a job for the jaw than a step in the hunt. puppies need it for a specific reason: they get 28 baby teeth by about eight weeks, start losing them around three and a half to five months, and finish with 42 adult teeth at around seven. that whole stretch aches, and something firm to work on helps.

plush, and grass, and anything with a filling is dissect. the last step before eating.

so there is no best toy, and never was. there's a sequence, and different dogs want to run different parts of it.

but only one of those steps turns material into a safety question.

the only question that matters

the toy aisle sorts dogs by bite strength: gentle chewer, moderate chewer, power chewer. you'll see those three words on a lot of packaging and a lot of vet clinic handouts.

i don't find that axis useful, and here's why.

bite strength describes how hard. dissection describes how.

kele has a soft mouth. he isn't a power chewer by anybody's chart. he is also the most methodical dismantler i have ever met — he doesn't crush things, he undoes them, patiently, from the seam. meanwhile a genuine power chewer can gnaw the same rubber ball for three months and never swallow a thing.

what puts a dog on an operating table isn't how hard he bites. it's what shape the pieces are, and whether they go down.

so there's really only one question, and it's a yes or no:

does your dog take things apart?

no. he plays with it and puts it down intact, more or less as he found it. then most of what follows doesn't apply to you. buy what he enjoys, check it now and then for damage, and get on with your life.

yes. then material isn't a preference. it's the whole decision.

i have the second kind. everything below is for you.

the materials, honestly

the stuffing is the least dangerous part of a stuffed toy — at least for the thing that sends dogs to surgery.

that surprised me. loose fibre fill is fluffy and discontinuous. it doesn't form a strand and it doesn't form a plug. small amounts pass.

what does the damage is everything around it. the fabric shell, which tears into long strips, and a strip is a rope by another name. the seams and ribbon. and the squeaker — a hard capsule, almost exactly throat-sized, sitting at the centre of the thing your dog is working towards.

so the honest advice on plush isn't “don't.” it's: retire it at the first torn seam, and know where the squeaker is.

and here's what nobody can tell you.

i went looking for a study showing polyester fill is harmless once swallowed. there isn't one. nobody has run it.

what exists is the obstruction literature, and when vets publish case series of what they actually remove from dogs, the list is bones, stones, plastic bags, fruit pits, wire, socks, cloth and whole toys. loose fill isn't on it. that's consistent with everything above about shape — but it's an absence, not a result, and i'm not going to dress it up as one.

there's also a finding pointing the other way. in 2025, researchers at sussex and exeter tested commercial pet foods and found microplastics in 76% of them. the most common polymer was polyester. sixty percent of the particles were fibres.

polyester fill is polyester.

so the honest picture: it passes, nobody has studied what a lifetime of small amounts does to a dog, and your dog is probably taking in more of it from his dinner than from his toys.

i'm not telling you that to sell you anything — i don't sell dog food. i'm telling you because “it's fine, it passes” was the answer i went looking for, and it turns out to be the answer nobody can actually give.

cotton rope. this is the one, and i think it's what that comment was really about.

rope is a continuous fibre. a dog can work a single strand out to thirty centimetres and it still won't break. that length is the entire problem. vets call the result a linear foreign body: one end catches and anchors, the gut keeps contracting to move things along, and instead of moving, the intestine bunches up along the strand like a curtain gathering on a rod. then the strand begins to saw through the wall from the inside. the outlook is worse than an ordinary blockage.

worth knowing now rather than later: if you ever see string, rope or fabric hanging out of either end of your dog, do not pull it. you can do real damage from the outside. that's a call to an emergency vet.

we sell rope toys and i'm not going to pretend otherwise. for a dog who doesn't take things apart they're excellent. for one who does, they're the thing on this list i'd watch hardest and retire earliest.

rawhide. the recommended alternative, and not a safe one.

i've tried it. we've had rawhide in this apartment, and i once got ambitious and made pig skin chews at home, from scratch, in my own kitchen. the smell is not something i can describe or have fully recovered from. so this isn't squeamishness from a distance.

rawhide doesn't dissolve. a dog doesn't break it down — they break it into chunks and swallow the chunks, and wet rawhide swells. a piece that went down easily can become a piece that won't come back out. there's a number that circulates about how much it swells; i couldn't find a source i trust, so i'm not repeating it. the documented part is enough: it swells, it doesn't break down, and it blocks things.

plastic and tpr. usually passes. but “usually passes” is a statement about the average dog and the average piece, and you have one dog and one piece.

pressed wood. a jaw job rather than a dissection job. the thing to avoid here is a real stick — wood splits along the grain, and a determined dog turns a stick into splinters pointed the wrong way. a pressed wood-flour chew wears down and flakes instead of splitting. it isn't natural wood and we don't claim it is.

grass. this is what i moved kele to, and i want to be exact about why, because i had the reason wrong at first.

i assumed grass was safer because it's more digestible than cotton. that isn't true. cotton and plant fibre are both cellulose and dogs digest neither. i was wrong, and a month ago i'd have told you the wrong thing confidently.

the actual reason is shape.

a grass ball cannot produce a thirty-centimetre strand. it comes apart into short, brittle, flat pieces — a few hundred of them, all over your floor. rope can produce that strand, and length is what makes a linear foreign body. same indigestible material, completely different failure mode.

it's also hollow, so there's no dense core to swallow whole, and cheap enough that you retire it early without arguing with yourself.

the honest limit: i haven't tested this. nobody has handed me a study comparing woven grass to cotton rope. what i have is a mechanism that makes sense, a dog who's been using them for months, and a willingness to say when i change my mind — which i've now done twice inside this article.

what's actually in ours

after that comment i went back to the factory and asked, in writing, what goes into the grass balls.

two of the styles they make do have something in them. one is bleached. another — the smooth, perfectly uniform one — is built around foam, held together with glue. we don't stock either, and we didn't before i asked.

the ones we do stock got the boring answer: cut, dried in a drying room, hand-woven. no bleach, no dye, no glue, no foam core.

i'm telling you about the two we turned down rather than announcing ours are natural, because all natural is a phrase anybody can type into a product page. we asked, two came back dirty, and those are the two we don't carry is a thing you can only say if you actually asked.

and since i've spent this long on stuffing: three of ours have it — the rec league, the stretch cat and the busy hands. their pages say so, and each says who it's for: light to moderate chewers, retire at the first torn seam, squeaker sewn in and not removable. they're here because plenty of dogs never take a toy apart in their lives, and for those dogs they're lovely.

i'm not going to delist them and i'm not going to pretend i don't sell them. i'd rather tell you which dog they're for.

the rules i actually follow

• answer the question first. does he take things apart. everything follows from that.
• take it away when it gets small. most of these stories end at the same point in a toy's life — the last third, when it finally fits down. a toy has a retirement date and it's earlier than you think.
• supervise the dissection. we hand children scissors and bikes and lego small enough to inhale, and what makes that survivable isn't a safe pair of scissors. it's an adult in the room. the toy doesn't decide the outcome; the fifteen minutes decide the outcome.
• nothing destructible when you're not there. that includes the pressed chews. supervised means supervised.
• give the drive somewhere to go. the one i'd have skipped a month ago. a cardboard box, a paper bag, an empty toilet roll — free, and it scratches the same itch. if your dog doesn't eat paper, that's a whole category you aren't using.

and while we're being honest

i drink coca-cola. i eat junk food. i know exactly what both do and i do it anyway, because knowing the risk and wanting the thing are two separate systems, and mine aren't wired together any better than yours.

so i'm not going to stand here pretending i make optimal decisions and then ask you to.

---

nothing in this shop is one hundred percent safe. neither is anything in any other shop, and neither is a stick from the garden.

but the conclusion is not that dogs should stop playing with things. that would be a terrible conclusion, and it would cost him more than the risk does.

the conclusion is smaller and more boring. work out whether he takes things apart. pick the material that fails in a way you can live with. retire it early. stay in the room.

that's it. that's the whole thing.

and to the person who left the comment: kele is my first dog and i'm still working it out. you were right about the strands. thanks for looking out for him.

go play.
