Indoor Games for Giant Breed Dogs: Summer Fun When It’s Too Hot Outside

When the pavement’s sizzling and the sun won’t quit, outdoor adventures take a backseat—and your big dog still needs an outlet.

Giant breeds like Great Danes, Mastiffs, and Saint Bernards may be less heat-tolerant than smaller pups, but that doesn’t mean they’re content snoozing all day. (Well, some snoozing, sure.)

Here’s how to keep your gentle giant mentally stimulated, physically engaged, and safely cool when temperatures rise.

Tug of War (Yes, Even for 150-Pound Dogs)

For dogs the size of small horses, a simple game of tug can be a full-body workout. Use a heavy-duty rope toy or a soft fleece tug and set boundaries—like “drop it” and “easy.”

This game taps into natural instincts, strengthens muscles, and gives your dog a satisfying outlet for energy—without ever leaving the AC.

Pro tip: Stand on a non-slip surface or rug so nobody (including you) eats it mid-tug.

Play Nose Games to Keep Big Dogs Mentally Stimulated

Hide treats around the room and let your dog use their nose to find them. You can start easy (behind chair legs or in open boxes) and build up to more challenging hiding spots.

It’s mentally enriching, naturally calming, and perfect for the couch-loving detective in your life.

Bonus: Try it with your dog’s dinner to slow them down and give meals more meaning.

Obstacle Courses Using Household Items

No, you don’t need a full agility setup. A couple chairs, a broomstick, and a blanket can become a crawl tunnel. Use couch cushions to create stepping zones or weaving lanes.

Keep it slow and safe—especially for older dogs or those with mobility concerns.

This is a great one for reinforcing training cues like "wait," "step up," and "go around."

Teach a New Cue or Trick

Indoor days are the perfect time to add new skills to your giant dog’s repertoire. Whether it’s “place,” “touch,” or a fun one like “spin,” short daily sessions help build mental muscle and deepen your bond.

Keep sessions short and sweet—5 to 10 minutes is plenty.

Muffin Tin Puzzle Game

This one’s quick to set up and surprisingly challenging. Drop some of your dog’s kibble or small treats into the cups of a muffin tin and cover each one with a tennis ball. Let them sniff, nudge, and work out how to get the goods.

Just make sure the tennis balls are size-appropriate and not a choking risk for your big dog.

Don’t Forget Cool-Down Time

Even indoor games can get intense—especially for giant breeds prone to overheating. Always give your dog a cool, comfy spot to recover, and keep plenty of water nearby.

Hardwood floors can be slippery for large dogs—lay down a rug or yoga mat in your play area to prevent accidents.

And if your dog decides they’re done after one round of “find it”? That’s fine, too. The goal is stimulation—not exhaustion.

Keep It Fun, Keep It Safe

Just because it’s too hot for long walks doesn’t mean your dog has to be bored. Indoor games give your gentle giant the stimulation they need to stay happy, healthy, and out of trouble.

So bust out the treat stash, roll out a rug, and get to playing.

Because bored big dogs? They get creative. And your furniture probably won’t appreciate it.
