Grooved, hollow and loud enough to be worth the effort.
Grooves alone rarely do much, because a dog moves the toy around constantly. Filling the hollow body is what keeps it working the same spot long enough for the ridges to have any effect.

Why you'll love it
An empty rubber toy gets a minute. The same toy with something smeared inside gets twenty, and that is where the chewing and the tiring out actually happen.
Most dogs will not tolerate a brush. Working enzymatic dog toothpaste into the grooves lets them do the scrubbing themselves. It is not a substitute for brushing, but it is something rather than nothing.
Hard plastic chew toys fracture into shards. Natural rubber deforms and tears instead, which is a much better failure mode in a dog's mouth.
Good fit if
Look elsewhere if
A plain grooved chew gets moved around the mouth constantly, so no part of the tooth surface gets worked for long. Put something the dog wants inside the toy and the behaviour changes: the dog holds it in one position and concentrates on getting the filling out, which is when the grooves are actually in contact with teeth for a meaningful stretch.
It also turns a five minute toy into a twenty minute one, and freezing the filling extends that further. The ridges running two ways across the body mean the contact is not confined to one angle, so a dog rotating the toy still gets some benefit rather than only working one face.
Wet food, plain natural yoghurt, mashed banana, pumpkin purée or the dog's own kibble soaked to soften it all work. Pack it in and freeze it for the longest result. As with any food holding toy, take the filling from the measured daily ration rather than adding it on top, since a stuffed toy twice a day quietly adds a substantial number of calories.
Peanut butter is the traditional filling and the one that needs a label check, because sugar free versions frequently contain xylitol, which triggers a dangerous insulin crash in dogs even in small amounts. Read the ingredients rather than assuming, and keep anything containing it well away.
At thirteen by nine centimetres this is built for small and medium dogs. Size matters for safety as much as for satisfaction: a chew small enough to fit entirely behind the back teeth of a large dog is a choking risk, so a big dog needs a bigger toy rather than a harder one. If the toy disappears into your dog's mouth, it is the wrong size.
Wash it by hand rather than in a dishwasher, since repeated hot cycles harden natural rubber and shorten its life. The hollow interior is the part that matters: use a bottle brush to reach the inside properly, because rinsing alone leaves residue in there that goes rancid within a couple of days.

The details
Loved by real pet parents
Empty, it gets a squeak and a sniff and that is that. Stuffed with a bit of paste and a few biscuits it keeps him lying down and working at it for a good twenty minutes, which is the only reason I get anything done. The hollow middle is wide enough to get a spoon into.
The rubber itself is holding up beautifully, no chunks missing and the grooves are as sharp as the day it arrived. The squeaker gave up after about four weeks of heavy chewing and now it only puffs. He still works at it for the filling, so it has not been a disaster.
I have opened chew toys before and had to leave them outside for a week to air. This one came out of the packet smelling of almost nothing, which meant he had it the same afternoon. Natural rubber that gives rather than cracks was what I was after and that is what it is.
It says small and medium dogs and I chose to ignore that, which is entirely on me. At 13cm our shepherd can get the whole thing in his mouth, so the tooth grooves never really come into contact with anything. Perfectly good toy, just order it for the size of dog it is meant for.
The ridges run both ways across the body, so a smear of paste sits in them rather than sliding off in one lick. That is what makes it last longer than a plain rubber toy. Warm water and a bottle brush gets it clean again afterwards.
Because of the shape it never comes off the ground the same way twice, so a throw down the garden turns into a proper chase. It is 152g, which is enough weight to throw but not so much that it hurts if it catches your shin. The blue one still looks new.
Six months of being left out on the lawn and the red has gone a fairly sad pink. The rubber is completely unaffected, no splits and nothing chewed off, so it is purely how it looks. He does not care, and I only mention it for anyone who leaves toys outside.
He has taken apart every hard plastic thing we have given him and left sharp bits on the rug. This one deforms instead of cracking, so a month of chewing has only left tooth marks in it. That difference is the reason it is still in the house.
Filling it is easy, emptying it is not. The hollow inside has corners a brush will not reach and paste dries in there, so it needs a long soak. Everything else is good, the squeak still works and the grooves have not worn down at all.
Good questions
It is sold for aggressive chewers, but no rubber toy survives a determined large dog indefinitely. At 13 cm it is sized for small and medium dogs; check it weekly and bin it once pieces start coming away.
Kibble, soft treats, peanut butter without xylitol, or dog toothpaste. Freezing it once filled makes it last several times longer.
Wash it by hand in warm soapy water. Filled toys need doing properly and often, because anything left in the grooves goes off.
Natural rubber holds up well against most small and medium dogs, but no toy is indestructible. Check it after each session and retire it as soon as pieces can be bitten off.
Wet food, plain yoghurt, mashed banana, pumpkin or soaked kibble. Freeze it for a longer session, count it within the daily food allowance, and check any peanut butter for xylitol.
Hand washing is better. Repeated dishwasher cycles harden natural rubber over time. Use a bottle brush to clean the hollow interior, which a rinse will not reach.

Advice
Buy for how your dog chews, not for how tough the packaging claims to be. And apply the thumbnail test before anything goes in a mouth.
