The hardest dogs to find in 101 Dogs Hidden in London are consistently those concealed by three main tricks: aggressive texture camouflage, multi-step interactive reveals, or extreme scale, where a dog is just a few pixels wide. This guide skips the obvious finds and laser-focuses on the final handful of dogs that trip up completionists, from the notorious Covent Garden 'Chameleon Corgi' to the pup you can only reveal by operating the Tower Bridge.
Most guides offer a simple checklist, but that won't help when you've been staring at the same scene for an hour. Success comes from understanding the methods the developers used to hide them. Before we pinpoint the most-missed mutts, let's break down the core principles of concealment you'll need to master.
The Art of the Impossible Find
Every truly difficult dog in the game falls into one of four categories. Once you learn to recognize the setup, you'll know what to look for. These aren't just random placements; they're deliberate puzzles designed to trick your brain's pattern-recognition faculties. Learning to see past the initial visual noise is the key.
- Texture Camouflage: This is the most common trick. The dog's color and pattern are designed to blend seamlessly into a complex background like brickwork, a pile of leaves, a patterned carpet, or a bookshelf full of similarly-colored books. Your eye glides right over it. The only way to spot these is to stop looking for a 'dog' and start looking for a dog-shaped outline.
- Interactive Reveals: These dogs are impossible to find until you interact with the scene. They might appear only after you click a light switch, open a drawer, pull a curtain, or solve a small sequential puzzle. If you've scanned a scene ten times and find nothing, start clicking on every plausible object.
- Scale & Obscurity: Some dogs aren't camouflaged but are either incredibly tiny or almost entirely hidden behind a foreground object. You might only see an ear and an eye peeking out from behind a pillar, or a minuscule dog sitting on a distant rooftop that's only a few pixels tall.
- Negative Space: The cleverest and rarest trick. Here, the dog isn't an object itself but is formed by the empty space between other objects. A famous example is the dog-shaped gap between two buildings or within the tangled lines of the Tube map.
The Top 5 Most Notorious Hounds
After combing through player forums and community discussions, a clear consensus emerges on which dogs cause the most frustration. Here are the five that will have you pulling your hair out, along with their precise solutions.
1. The Covent Garden 'Chameleon Corgi'
This is, without a doubt, the most frequently missed dog in the game. It’s a masterclass in texture camouflage. In the bustling Covent Garden market scene, look for the area with the old cobblestones to the left of the street performers.
- The Trick: The corgi is lying down, and its brindle fur pattern is almost identical to the color and texture of the worn, mottled stones. Its outline is incredibly soft.
- How to Find It: Stop looking for a whole dog. Instead, look for its two distinct, black-tipped ears. They are slightly darker than the surrounding cobblestones and are the only part of the dog that breaks the pattern. Scan the lower-left quadrant of the cobblestone patch; it's nestled between a darker grey stone and a slightly brown one.

2. The Tower Bridge Gear Dog
This dog is locked behind a simple interactive puzzle. In the Tower Bridge scene, the bridge is initially raised, and the dog is nowhere in sight. Many players scan the sky, the water, and the towers themselves, never realizing they need to change the scene's state.
- The Trick: The dog is etched onto the bridge's internal mechanics, which are only visible once the bridge is lowered.
- How to Find It:
- Locate the small control booth on the south bank of the Thames (the right side of the screen).
- Click on the large green lever inside the booth. This will trigger an animation that lowers the two halves of the bridge.
- As the bridge locks into place, a large gear mechanism is briefly exposed at the base of the right-hand tower. The dog is a faint etching on the largest, central gear. You only have a few seconds to click it before the housing covers it again.

3. The Underground Map Mutt
A brilliant example of a negative space puzzle. Inside any of the Underground station scenes (like the one at Baker Street or Piccadilly Circus), find the large wall map of the Tube network. You're not looking for a dog printed on the map.
- The Trick: The dog is formed by the white space created by the intersection of the Circle (yellow), District (green), and Piccadilly (dark blue) lines near the Westminster station icon.
- How to Find It: Look at the tangle of lines around Westminster. The way the yellow and green lines curve around the straight blue line creates a perfect, seated dog shape in the negative space between them. The 'head' is formed by the curve of the Circle line. Click the empty space, not the lines themselves.
4. The Shard's Reflected Pooch
This one combines interactivity with a clever use of perspective. In the scene overlooking the city from near London Bridge, The Shard dominates the skyline. The dog is not on the building itself.
- The Trick: The dog is only visible as a reflection in the glass of a nearby office window in the foreground, and only after you've 'cleaned' the window.
- How to Find It: In the bottom right of your screen is a modern office interior. Notice the large window is slightly grimy. On the windowsill is a cleaning cloth. Click the cloth first, which will wipe the window clean. Now, look at the reflection of The Shard in that freshly cleaned glass. A small, white dog will be visible, seemingly sitting on one of the building's angled edges in the reflection.
5. The Double-Decker's Tiny Passenger
An exercise in pixel-hunting. In the busy Piccadilly Circus scene, several red double-decker buses are either parked or moving. This dog is a triumph of the 'Scale & Obscurity' principle.
- The Trick: The dog is minuscule and looking out of a specific window on one of the buses.
- How to Find It: Find the stationary double-decker bus on the far left of the scene, the one with the number '23' on the front. Look at the windows on the upper deck. In the fourth window from the front, a tiny, brown dachshund is peeking out, with only its head and snout visible. It's no more than 10-15 pixels high and easily mistaken for a simple shadow or smudge.

Zone-by-Zone Hit List for Other Tough Hides
Beyond the top five, nearly every scene has at least one dog that uses these advanced tricks. If you're stuck in a specific area, this quick-reference table might have the answer.
| Location | Dog Description | The Trick |
|---|---|---|
| Westminster Abbey | Stained Glass Spaniel | Found within the stained glass window on the far right. Its colors are part of the glass design. It only becomes clickable after you find and click a candle to 'illuminate' the window. |
| The British Museum | Hieroglyphic Hound | In the Egyptian exhibit, look at the large stone tablet covered in hieroglyphs. One of the symbols in the third row from the bottom is actually a cleverly drawn dog in the Anubis style. |
| Baker Street | The Detective's Dog | Look at the famous statue of Sherlock Holmes. The dog is not on the statue, but is the shape of the shadow the statue casts on the pavement. The shadow's outline forms a perfect basset hound. |
| Trafalgar Square | The Lion's Friend | A tiny white dog is sleeping between the paws of the northernmost Landseer Lion statue. It's heavily shadowed and blends in with the bronze. |
| The London Eye | The Pod Pup | This dog is on the outside of one of the passenger pods. You must wait for the pod with a distinctive red stripe to rotate to the very top of the wheel to be able to click it. |
The Final Dog: Unlocking the "Good Boy" Achievement
If you're stuck at 100 dogs and can't find the last one, stop searching the scenes. The 101st dog is an 'easter egg' that only becomes available after the first 100 are found.
The secret to the 101st dog is to return to the main menu screen.
Once you've collected the 100 standard dogs, re-launch the game. On the title screen, which shows a collage of London landmarks, a new, small, golden retriever puppy will now be sitting on top of the 'O' in the word 'London' in the game's title. Click it to secure your 101st dog and the final achievement.
Frequently Asked Questions
What's the absolute hardest dog to find in 101 Dogs Hidden in London? While subjective, most players name the 'Chameleon Corgi' in Covent Garden due to its perfect texture camouflage. The Negative Space dog on the Tube map is a close second, as it requires a different way of looking at the scene.
Is there a dog inside Buckingham Palace? No, the palace itself is not an interactive area. However, check the palace gardens carefully. One of the sculpted topiary bushes on the left is trimmed into the shape of a poodle. This is one of the more commonly missed dogs in that scene.
Do the dogs ever move? No, all 101 dogs are in fixed, static positions. However, some are located on moving objects, like the London Eye or a passing boat on the Thames. For these, you may need to time your click for when the object is in the correct position.
I'm stuck at 100 dogs. Where is the last one? This is the most common question. The 101st dog is not in any of the main scenes. After you find the first 100, you must go back to the game's main menu. The final dog will have appeared on the game's logo itself.
A Final Tip
Finding every dog in 101 Dogs Hidden in London is a true test of observation. When you get stuck, take a break and come back with fresh eyes. Remember to think like the designers: look for camouflage, click on everything that looks interactive, and never forget to check the negative space. It's not just about finding dogs—it's about learning to see the unseen.
