This is the complete 100% achievement guide for 101 Dogs Hidden in London. Unlocking all 10 achievements is a quick and relaxing process, achievable for most players in under 30 minutes. The primary challenge lies not in finding the dogs, but in executing a perfect, no-misclick run for the elusive "Good Boy" achievement. This guide breaks down every requirement, from the basic collection milestones to the special hidden objectives.
There are a total of 10 achievements to earn. Five are for finding all 101 dogs, four are for interacting with game mechanics, and one is for finding the secret cat. None are missable, as you can replay the level at any time, but perfectionists will want to aim for a single, flawless run.
The Core Canine Collection (5 Achievements)
These five achievements form the backbone of the game and will unlock naturally as you play. The core objective is simple: scan the sprawling, hand-drawn illustration of London and click on every dog you see. The dogs are cleverly integrated into the architecture, crowds, and scenery, but none are unfairly hidden.
- Dog #1: Unlocks upon finding your very first dog.
- 25 Dogs: Unlocks after clicking on 25 unique dogs.
- 50 Dogs: Unlocks at the halfway point, after finding 50 unique dogs.
- 75 Dogs: Unlocks after finding 75 unique dogs.
- 101 Dogs: Unlocks when you find the final, 101st dog, completing the main collection.
There is no time limit, so you can take as long as you need. Use the mouse wheel to zoom in and out and click and drag to pan across the cityscape. The dogs vary in size and obviousness, so a systematic approach is recommended. Mentally divide the map into a grid and clear one section at a time to ensure you don't miss any.
Beyond the Barks: Secret & Special Achievements
Beyond finding the dogs, there are five other achievements tied to specific actions and hidden secrets. These are what separate a casual playthrough from a 100% completion.

The "Meow" Achievement: Finding the Hidden Cat
As is tradition in many hidden object games from developer NaipSoft, there's a secret cat hidden amongst the canines. Finding this feline friend unlocks the Meow achievement.
- Location: The cat is cleverly tucked away on the far left side of the map. Look for the Tower Bridge. Just to the left of the bridge's base, on the near side of the river, there is a small, dark-colored cat sitting on a wooden pier piling, partially obscured by a red railing. It's easy to overlook, as its dark fur blends in with the shadows of the pier.
The "Woof" Series: Mastering the Bark
Three achievements are tied to the "Woof" button, a feature in the bottom right corner of the screen that highlights a random, unfound dog. While it functions as a hint system, its use is also an achievement requirement.
- Woof: Click the "Woof" button 10 times.
- Woof Woof: Click the "Woof" button 50 times.
- Woof Woof Woof: Click the "Woof" button 101 times.
Crucially, you can simply spam-click the button 101 times at any point—even after finding all the dogs—to unlock all three achievements at once. You do not need to find the dog it highlights for the click to count.
The "Good Boy" Achievement: A Perfect Score
The single hardest achievement in the game is Good Boy. The requirement is to find all 101 dogs without a single misclick. This means every click you make must successfully find a dog. If you click on any part of the background that is not a dog, you void the achievement for that run and must restart the level.
This demands patience and precision. The best strategy is to zoom in significantly on a dog before clicking to minimize the chance of error. If you are even slightly unsure, move on and come back later. There is no penalty for taking your time, so a slow, deliberate pace is your greatest asset.

Navigating the Game: Mechanics and Tips
While the gameplay is straightforward, understanding its few systems can make the 100% run smoother, especially the no-misclick challenge.
Using the Zoom and Pan Controls
Effective navigation is key. The zoom function (mouse wheel) is essential for inspecting dense areas like crowds or detailed buildings. Some smaller dogs are barely visible when fully zoomed out. Pan across the map (click and drag) in a consistent pattern, such as left-to-right, top-to-bottom, to ensure you cover the entire area without getting disoriented.
Color Modes and Accessibility
The game offers three distinct color modes accessible from the main menu: Normal, Sepia, and Black & White. You can earn achievements in any of these modes. Sometimes, switching between them can help you spot a tricky dog. The high contrast of the Black & White mode can occasionally make a dog's outline pop from a similarly-colored background, while the Sepia mode offers a softer, vintage feel.
