Rain outside, a bored dog inside. You know the look: the big sigh, the pacing, the long stare at the leash hook. The good news is that you can tire out a dog without setting foot outdoors. Sniffing, searching and short bursts of training all give a dog's brain a workout, and mental work wears most dogs out faster than you'd expect.

The simplest rainy day enrichment comes down to a handful of ideas: snuffle games that put your dog's nose to work, hide-the-treat searches around the house, puzzle feeders that turn mealtime into a project, and quick training games using small pieces of biscuit. You don't need fancy gear. A towel, a muffin tin and a pocket full of treats will carry you through most soggy afternoons.

Why does sniffing tire a dog out?

Dogs explore the world nose first. A walk around the block is mostly a sniffing tour, and when the weather cancels that tour, your dog misses more than the exercise. Giving your dog things to sniff out indoors fills that gap.

Sniffing is calm, focused work. Many dogs come away from a good search session ready for a nap, which is exactly what you want when the house feels small.

How do you play snuffle games at home?

A snuffle mat is a fabric mat with lots of fleece strips that hide small bits of food. Your dog noses through the strips to find them. If you don't own one, a few household items work just as well:

• The towel roll. Lay a towel flat, scatter small treats across it, then roll it up loosely. Your dog unrolls it to collect the goods. Fold the ends in for an extra challenge.
• The muffin tin. Drop a treat in some of the cups and cover every cup with a ball or a crumpled sock. Your dog has to figure out which ones hold the prize.
• The box pile. Toss a few empty cardboard boxes on the floor and scatter treats inside and around them. Some dogs love the rummaging as much as the treats.

Stay nearby while your dog plays, pick up any shredded cardboard or fabric when the game is done, and put the gear away between sessions so it stays special.

How do you teach a dog to find hidden treats?

Hide-the-treat is a classic for good reason. Most dogs pick it up quickly, and you can make it harder as your dog gets better at it.

1. Start in plain sight. Have your dog sit and wait (or have someone gently hold the collar). Set a treat on the floor where your dog can see it, then say a cue like "Find it!" and let them go.
2. Add a little cover. Next time, place the treat behind a chair leg or under the edge of a rug.
3. Hide it out of sight. Once your dog has the idea, hide treats while they wait in another room, then release them with the same cue.
4. Hide yourself. For a twist, hide behind a door with a treat in hand and call your dog to come find you.

If your dog gets stuck, help out by pointing or moving closer. The goal is a dog who wins often and wants to keep playing.

Are puzzle feeders worth it?

For a lot of dogs, yes. Puzzle feeders and treat-dispensing toys slow down eating and turn a meal that vanishes in seconds into a little problem to solve. On a rainy day, serving part of your dog's regular meal in a puzzle toy is an easy way to add enrichment without adding extra food.

Start on the easiest setting so your dog gets rewarded quickly. If your dog walks away, paws at it in frustration or starts chewing the toy itself, make it easier. Supervise until you know how your dog handles a new toy, and wash it regularly.

What training games work well indoors?

Short training sessions are some of the best rainy day activities. Keep each round brief and stop while your dog is still eager. A hallway or living room gives you plenty of space.

Small rewards make this work. Breaking a biscuit into little bits means your dog earns lots of rewards without eating a lot of food. A few games to try:

• Hand touch. Hold out a flat palm and reward your dog for bumping it with their nose. It is a handy skill for moving your dog around the house later.
• Go to your mat. Toss a treat onto a mat or bed, reward your dog for stepping onto it, and slowly build up to them lying down there.
• Which hand? Hide a treat in a closed fist, offer both hands and reward your dog for picking the right one.
• Brush-up practice. Run through sit, down and stay, adding a bit more distance or a few more seconds each round.

If you'd like help with a trickier behavior, a qualified trainer who uses reward-based methods can give you a plan.

How many treats is too many on a rainy day?

A games day can rack up treats fast. Treats count toward your dog's daily food, so it helps to keep a rough tally and trim the meal a little if the treat pile gets big. Your vet can tell you how much your dog should be eating in a day.

Small pieces go a long way here. Breaking treats into smaller bits stretches them across a whole training session. Treats are a reward, not a complete diet, and fresh water should always be out.

A few safety basics for indoor games

• Supervise any game with boxes, towels, socks or toys your dog could chew up.
• Keep hiding spots away from trash, cleaning supplies, cords and any foods dogs shouldn't have.
• Watch for frustration and make the game easier when you see it.
• If your dog has special dietary needs, check with your vet before adding new treats.

Making the most of a stuck-inside day

You don't need to fill every hour. A sniffing game in the morning, a puzzle feeder at lunch and a quick training round before dinner can turn a restless dog into a snoozing one.
