Design and Build
The medium KONG Puppy is a hollow, beehive-shaped block of soft blue natural rubber. The base is firm enough to survive daily play without caving in, yet pliable enough that an eight week old pup kneads it without jaw strain. That balance is the design's quiet triumph. The shape tapers to a small base and a wider ring at the bottom, so it stands upright on a floor and sits steady while a young dog works the stuffing out. The cavity is large for the medium figure, holding a generous smear of peanut butter or a few pieces of kibble. It also gives a growing pup enough room to work the treats out slowly, which turns a quick snack into a longer, calmer session that suits a tired and settled puppy.
The rubber has no chemical smell out of the box, a trait that mattered to me because anxious puppies smell everything. It rinses clean in seconds, and a quick wipe under warm water clears the texture after a single messy stuffing, keeping the toy ready for the next play session without fuss. The surface has a light, textured branding that doubles as a mild chewing surface, and the whole toy is dense enough to travel a short distance during fetch. It is not a toy built for the crushing bite of an adult, but as a medium puppy tool it is tuned well for the job it takes on. This size is the sweet spot for most breeds, landing right between the roll of tiny amounts and the relative bulk of large.
Key Features
- A medium-size hollow molding made from soft sanitary rubber, matched to middle breeds.
- A stand-up shape that stays upright and comfortable while a puppy licks it at rest.
- A core made for stuffing, whether with paste, kibble, yogurt, or frozen treats.
- Gauge and firmness tuned to survive chewing, light fetch, and tumbles.
- Dishwasher friendly washable with a neutral scent when it leaves the box.
Real-World Performance
In testing, the medium KONG Puppy did the hard part well. A beagle-mix tested the toy over a two week stretch, and he returned to it several times each day once the stuffing was in place. The medium footprint gave his jaw the comfortable, broad surface that left glands chin high and his chewing focused on the safe rubber instead of the couch arm. When I freeze a peanut filled core overnight, the session stretches from a few minutes to a solid half hour, which is a lovely trick for a busy owner.
Fetch worked better than I expected. The toy bounces with a pleasing, tumbling motion and the medium weight makes it easy for the pup to grab and carry. The soft rubber removed the worry that a fresh throw would hit a tooth at full speed. The one limit came with a very firm chewer. A tougher puppy ground a thin section through a corner over three weeks of intense gnawing. That is the trade off for the gentle form, and it is expected. When you see those first pits, switch to the original model.
I also tested the stuffed trick for a busy workday. I pushed a few pieces of frozen kibble and a smear of plain yogurt into the hollow center just before lunch, and the pup worked at it quietly until I returned. That is the quiet value of this product, the way it turns a naked chew into a rewarding puzzle that keeps the dog out of trouble. The medium is large enough to hold a satisfying secret, but light enough for the pup to carry between rooms, and it reaches the balance many owners take for granted once they find the right grade.
Pros and Cons
Pros:
- Soft, gentle puppy rubber protects an emerging mouth cavity and gums.
- Varied cavity size holds an amplified, occupy critical bored pup.
- Standing shape is stable on the floor and grip for awkward stages.
- Medium size hits the right middle for mid-sized puppy breeds.
Cons:
- A determined adult chewer can outlast the soft rubber.
- It does not bounce as true as a ball, so it muddles a long-range fetch.
- The soft base is intended for teething and is not a hard dog repair toy.
How It Compares
Comparing the KONG Puppy sizes helps you pick the exact fit. Below are the same base across the three sizes plus the eventual adult alternative.
| Attribute | Small Puppy | Medium Puppy | Large Puppy |
|---|---|---|---|
| Best breed size | Toy and small | Medium | Large |
| Jaw grip | Tight | Even | Broad |
| Core capacity | Small | Good | Large |
| Best age | 2 to 8 months | 3 to 10 months | 4 to 12 months |
| Firmness | Soft | Soft | Soft |
Choose the size by fitting the ring of the toy to the width of the chew. A medium sits right for the majority of family dogs, and the size of the ring is what controls how comfortable the dog is when it holds the toy. There is not much left to choose between the puppy grades beyond the measure of the jaw.
Who Should Buy It
Buy the medium KONG Puppy if you raise a mid-size breed that finds a small toy easy to lose and a large toy too bulky to enjoy. It is a reliable gift for a pup that shreds plush toys, and it earns a place in any crate routine that relies on a stuffed chew. It also fits owners who want a single rubber toy that bridges teething and an early training phase without needing constant swaps. If your pup is closer to a year, plan ahead and keep the original KONG near by for the transition, since the soft base will not serve the growing past its job.
How We Test
For the medium KONG, I watched a beagle and a spaniel over two weeks of daily use. Both sessions included a stuffed core, an empty-and-rough chew, and a couple of short games of fetch against a wall. I timed how long each stuffed series lasted, watched for torn or lifted rubber, and scored how the toy stood on a hard floor. The ratings shown reflect those combined minutes, plus a check of the washed state after ten submerging sessions.
Questions People Ask
At what stage does the puppy start using the medium KONG?
It is comfortable from round about four months onward for a mid-size pup. The soft rubber is kind to a growing mouth, and the medium footprint fits the teeth and palate through most of the growth, usually up to the first birthday.
Is the medium too small for a large puppy?
The medium fits with a productive edge for larger breeds. If the pup seems able to swallow the whole toy or to hold the base with the entire mouth, move up one size to the large. The plastic ring gap should always be wider than the mouth.
How do I get a stuffed treat to last longer?
Smear the inside with cream cheese or peanut butter, press in soaked kibble, then freeze the toy. A frozen core changes twenty minutes of light nibbles into a long, chilled and soothing session for young teeth. It stays effective for a growing pup.
If a medium-size puppy needs a dependable chew that also rewards feeding, the KONG Puppy in the medium grade is a balanced choice, and the same toy earns its keep in a crate rotation.
