Something is Wrong With My Dog walkthrough: Night Guide, Behavior Cues & All Endings

What Is Something Is Wrong With My Dog?

Your dog scratches at the back door at 2 a.m. You let him in. Except your actual dog has been asleep on the couch this entire time. That skin-crawling premise is exactly what this Something is Wrong With My Dog walkthrough is built to solve. The short indie horror game drops you into a quiet house at night, hands you one job — figure out whether the animal in front of you is really your dog — and then does everything in its power to make you doubt your own eyes.

The game found a second life on TikTok, where spooky-season creators began posting clips tagged #cursedtiktoks and #spookyseason. One viral post from creator Mar$ pulled in more than 3 million views, and comment sections quickly filled with players comparing notes on the mimic's behavior and begging for a reliable Something is Wrong With My Dog walkthrough that actually explains the endings.

Here's the quick rundown before we dig in:

If you want to try it yourself first, it sits alongside thousands of free indie horror games on itch.io, which remains the go-to platform for short, experimental horror projects like this one. Otherwise, keep reading — the full walkthrough is below.

Something is Wrong With My Dog Walkthrough: Night by Night

This Something is Wrong With My Dog walkthrough follows the three-night loop that community playthroughs consistently describe. Exact event order can shuffle a little between versions — several players report minor anomalies randomizing between runs — but the core beats and the decision points that lock your ending stay the same. The golden rule across all three nights: verify before you trust.

Night 1: Learn the Baseline

The opening act is deliberately boring, and that's the point. Feed your dog, pet him, watch him blink, breathe, and jingle his collar as he wanders the house. Treat this like a study session. Player experience is unanimous here: every cue the game later uses to trick you is telegraphed in this safe intro. Note the sound his nails make on the floor, how he reacts to his name (slowly, groggily, like a real animal), and where his water bowl sits. When the game prompts you to sleep, sleep.

Night 2: The Scratching at the Door

Around the halfway point, you'll hear scratching at the door while — if you look carefully — your dog is still visibly inside. This is the walkthrough's first real decision. Per community reports, the reliable sequence is: call his name, check his collar, and shine your light before touching any door. The real dog responds slowly and imperfectly. The thing outside responds instantly, or not at all. Do not open the door on reflex; doing so is the most common way players lock themselves into the bad ending on a first run.

Night 3: The Final Comparison

The last night collapses the trick entirely: you'll be presented with two versions of your dog, or one version that's already inside the house. This is where the behavior table below becomes your cheat sheet. Compare the cues side by side, commit to an answer, and make your choice. There's no timer, so take your time — the game is testing patience, not speed.

Real Dog vs. Mimic: Every Behavior Cue

Everything in this table is pulled from aggregated player experience across community discussions. Not every cue appears in every run, but learning them all makes the finale trivial.

Two practical notes from players. First, play with headphones — audio tells are the most consistent cues in the entire game, and laptop speakers flatten them. Second, the friendliest, most eager dog is almost always the wrong answer. Real animals are lazy and imperfect; the thing wearing your dog's face performs.

All Endings Explained

Community guides name the endings slightly differently depending on the version, but players consistently report three outcomes. Spoilers are kept deliberately light below.

The secret ending is the one most players miss on a blind run, because it requires you to deliberately do nothing in a game that keeps nudging you to act. It takes about five extra minutes and is absolutely worth seeing once.

Survival Tips and Common Mistakes

A good Something is Wrong With My Dog walkthrough can only take you so far — the final choice is always yours. These habits, drawn from recurring advice across player experience threads, will carry you through.

A few extra pointers worth knowing before your first run:

• Short runs, big payoff. One playthrough takes 15–30 minutes, so seeing every ending costs you less than two hours total.
• Anomalies can shuffle. Multiple community reports note that the order of minor events randomizes between runs, so a second playthrough won't feel like a rerun.
• There's no combat or fail-state pressure. This is an observation game. If you die (so to speak), it's because you chose wrong — which means the fix is always a better decision, not faster reflexes.
• Mirror checks matter. In several versions, reflective surfaces show the mimic's true face a half-second early. Make glancing at mirrors part of your route.

The single most common first-run mistake, by a wide margin, is opening the door on Night 2 out of pure instinct. Horror games train us to answer doors; this one punishes it. Slow down, run the verification checklist, and you'll walk straight into the good ending.

Frequently Asked Questions

Is a Something is Wrong With My Dog walkthrough really necessary, or can I beat it blind? You can absolutely finish a run blind — the game is short and forgiving. A walkthrough mainly helps you avoid the Night 2 door mistake, decode the behavior cues quickly, and unlock the secret "Alone" ending, which is nearly impossible to find on a first attempt without knowing the no-interaction requirement.

How long does it take to get all three endings? Based on player experience, one run takes 15–30 minutes, and a completionist run through all three endings lands around 1.5 to 2 hours, including a replay or two if randomized events trip you up.

Where can I play it, and is it free? Community reports consistently point to itch.io as the home base, where it's free to play in-browser or download, with optional donations to the developer. It runs fine on modest hardware — no dedicated GPU required.

Is the game connected to the viral TikTok meme? The game leans into the same creepy-pet trend that exploded on TikTok, where clips tagged #cursedtiktoks — like the viral spooky-season post from creator Mar$ that cleared 3 million views — made "something is wrong with my dog" a shared internet nightmare. The game isn't based on a true story, but it taps the exact same fear: that the animal you love might be wearing a mask.
