That first flash of tiny front teeth usually happens by accident.
Nails click across the kitchen floor. You look down. Your long, low shadow is gazing up at you with a wrinkled muzzle, a curled lip, and a neat little row of white teeth that were absolutely not on display ten seconds ago.
Half a second of panic. Then you melt.
Here is the good news: that expression is trainable. Not fakeable, not forced, but catchable and repeatable, which is exactly what you want if you have ever tried to get a decent photo of a sausage dog who moves like a caffeinated eel.
This is a step by step plan for teaching that goofy grin on cue, plus the safety checks that separate a happy smile from a dog who is quietly asking you to back off.
First, Understand What You Are Actually Training
A dog smile is not a human smile. Dogs do not lift their lips because they find your joke funny.
What you are working with is a behavior called the submissive grin, sometimes called a greeting grin. The dog pulls the front lip up and back, usually while wiggling, squinting, and generally acting like a noodle with anxiety about being loved too much.
The Difference Between a Grin and a Warning
This part matters more than anything else in the article, so read it twice.
A friendly grin comes with a loose, wiggly body. The eyes are soft or squinty. The ears are relaxed or pinned back in that happy, sheepish way. The whole dog looks like it is apologizing for existing.
A real smile is never just a mouth. It is a whole body doing something silly at the same time.
A warning is different. The body goes stiff, the eyes go hard and round, the weight shifts forward or freezes in place, and you may see a wrinkled nose with a low rumble underneath. If you see that, stop the session entirely and give the dog space.
Dachshunds are dramatic, but they are also honest. They will tell you which one they are doing.
Why Doxies Are Weirdly Good at This
Long muzzle, expressive lips, strong opinions.
Many dachshunds already do a version of this when you come home, when they get caught doing crimes, or when they want something from the person holding the cheese. That existing tendency is your raw material, and it means you are shaping something natural rather than inventing it from scratch.
Some individual dogs simply never offer it. That is normal too, and no amount of training will manufacture a facial expression a dog does not naturally produce.
Before You Start: The Setup
Five minutes of preparation saves you three weeks of confusion.
What You Need
A soft, high value treat that your dog can swallow fast: tiny bits of chicken, cheese, or freeze dried liver. Nothing crunchy, because chewing wrecks your timing.
A marker. A clicker works beautifully, but a short word like yes works just as well if you say it the same way every time.
A quiet room with no toddlers, no doorbell, and no other dog trying to intercept the payroll.
Timing Your Sessions
Keep sessions to two or three minutes. Seriously.
Dachshunds have a short patience budget and a long memory for boredom. Two good minutes twice a day will beat one grim fifteen minute marathon every single time.
Train when your dog is already a little bit excited but not completely unhinged: after a nap, before a meal, or during that happy stretch when you first walk in the door.
The Step by Step Plan
Step 1: Find Your Dog’s Personal Trigger
Sit on the floor at your dog’s level and watch closely.
Try the things that usually spark that goofy greeting face: baby talk, gentle chest scratches, a soft ear rub, saying their name in a ridiculous voice, or crouching down and letting them come to you.
You are hunting for the moment the lip twitches upward, even slightly. It might last a quarter of a second, and it might be so small that you almost miss it.
Step 2: Mark the Micro Moment
The instant that lip moves, mark it. Click, or say yes, then deliver the treat immediately.
Do not wait for a full toothy grin. A tiny lip lift is the first brick in the wall, and if you hold out for perfection you will be sitting on that floor until Thursday.
Reward the twitch today and you will be rewarding the full grin by the weekend.
Repeat this five or six times, then quit while your dog still thinks it is a great game.
Step 3: Raise the Bar, Slowly
Once the small lip lift is happening reliably, start marking only the slightly bigger versions.
This is called shaping, and it works because your dog is constantly experimenting: if the little twitch stops paying, the dog naturally tries a bigger one.
Move up in tiny increments. If your dog gets confused and stops offering anything at all, you jumped too far, so drop back to the easier version and pay generously for a few reps.
Step 4: Add the Cue Word
Only add a word once the grin is happening predictably. Adding it too early teaches your dog that the word means nothing.
Say your cue just before you expect the smile to appear. Keep it short and distinct: smile, cheese, or teeth all work fine.
The order is always the same. Cue, then trigger, then grin, then mark, then treat.
Do that for several days. Your dog is quietly learning that the word predicts the whole sequence.
Step 5: Fade the Trigger
Now you take the training wheels off.
Say your cue, then pause for two or three seconds and do absolutely nothing else. Resist the urge to fill the silence with baby talk.
If your dog offers the grin during that pause, throw a party: mark it, treat it, and act like they have just solved a complicated equation. If nothing happens, calmly add the old trigger, reward a smaller version, and try the pause again on the next rep.
This step usually takes the longest. It is also the step where the behavior becomes genuinely yours to ask for.
Step 6: Proof It in New Places
A trick that only works on the living room rug is a party trick with commitment issues.
Practice in the kitchen. Practice in the yard. Practice with your partner holding the treats, then with the neighbor, then during a walk when the world is full of distracting smells.
Expect a temporary dip in quality each time the setting changes, and lower your standards for a few reps to help your dog succeed.
Step 7: Get the Photo
Camera first, cue second.
Set your phone up, get the framing right, focus on the eyes, then give the cue. Burst mode is your friend, because dachshund smiles are fast and your reflexes are not.
Reward the dog even when the photo is a blurry disaster. The smile earned the treat, not the photograph.
Troubleshooting the Common Mess Ups
"My Dog Just Stares at Me"
Your trigger probably is not exciting enough, or your dog is too focused on the food.
Try hiding the treats in a pocket, using a softer voice, and letting the dog approach you rather than looming over them.
"The Lip Goes Up, but So Does the Growl"
Stop the session and reassess.
Some dogs get frustrated when the rules feel unclear, and frustration can look like a smile that went sour. Make the criteria easier, shorten the session, and finish on something your dog already knows well.
Any trick that costs your dog comfort is not worth the photo you were going to post.
"It Worked Yesterday and Vanished Today"
Completely normal, and slightly maddening.
Behaviors are wobbly while they are new, so go back one step, pay well for a few easy repetitions, and finish early.
A Realistic Practice Week
Days one and two: catch and mark tiny lip lifts only, two short sessions daily.
Days three and four: shape bigger grins and start pairing the cue word.
Days five and six: introduce the pause and begin fading the trigger, keeping every session under three minutes.
Day seven: take it to one new room, lower your expectations, and reward the effort more than the polish.
