Is your senior dog spending more time lounging on the couch than they did in their younger days? What about signs of boredom like barking more, licking, or acting lethargic? Just because your dog is older doesn’t mean their life should be boring!
In this post, I’ll show you how to adapt my popular DIY Busy Box enrichment toy for senior dogs and dogs with limited mobility.
Seeing senior dogs’ lives resort to sitting on the couch or not leaving the yard makes me so sad. I remember seeing my last senior dog spending her days sitting on the couch a lot. That was over 10 years ago.
Now, I’ve been a dog mom for over 25 years and even got certified as a canine enrichment expert. And when you know better, you do better. So I’m passionate about sharing senior dog enrichment ideas because if you have a dog, one day they will be a senior. So this advice can help everyone who loves a dog.
In the post below, I share how I modified our favorite busy box enrichment game to be safer and more accessible for senior dogs – inspired by my own seniors, Burt and Lucy, who are now 13.

What is a Busy Box for Dogs?
A Busy Box is one of my favorite canine enrichment activities! Lucy and I have even demonstrated how to do it on TV!
Basically, it’s a way to make a DIY dog puzzle out of recyclable items you already have around your home. Grab cardboard boxes, packing paper, yogurt containers, egg cartons and other safe containers.
Then you build your “puzzle” by adding your dog’s favorite treats or their food in every layer/container. Don’t overdo it here! Just 1-3 pieces of kibble in a yogurt container is plenty when you combine it with some loose kibble in the box.
Once your “puzzle” is complete, hand it over to your do and let them rip it open, dig through the contents, sniff out the treats and eat their treasure.
This is a wonderful enrichment activity because it’s different every time. I love that it’s FREE by using stuff you already have at home AND it’s eco-friendly because you’re getting an extra use out of all your recyclables before they go to the curb.
The busy box is seriously one of my favorite things to do for my dogs, but we haven’t been doing it lately. And there’s a big reason why.

How Cancer Changed Playtime for My Senior Lab
In December 2024, my labrador Lucy was diagnosed with cancer at 12 years old. This was devastating news, and it’s been an emotional roller coaster since then.
Lucy has a giant mass on her spleen that’s been aggressively growing. I’m doing all that I can to treat her cancer without surgery or chemotherapy. And the vet said to be careful about activities where she could get bumped in the belly.
Recently, I was in my basement looking at my stash of busy box supplies. I save every box, yogurt container, and egg carton. I’m a little bit of a hoarder of busy box supplies!
Anyhow, it made me sad that we weren’t using these supplies since Lucy’s diagnosis. Seeing all the unused supplies made it sink in that Lucy won’t be with us much longer.
But we have so many great memories of playing with this stuff… busy boxes were one of her absolute favorite activities!
I had to find a way to bring back this enrichment activity that Lucy loves so much!
I thought about how I could modify the busy box for her safety – we don’t want to bump that belly or over do it.
Another thing that’s prevented us from playing with the busy box supplies is that Lucy has been on a special home-cooked diet since I found out about her cancer. That food wouldn’t work in a cardboard box situation.
But I can’t let these little bumps in the road stop Lucy from enjoying one of her favorite activities!

I Knew My Senior Dog Needed More Brain Games
I’ve been a dog mom for over 25 years, but I wasn’t always an expert. Looking back, I remember seeing my previous senior, Lola, struggle with boredom. She spent a lot of days snoozing on the couch. It’s normal for senior dogs to sleep a lot, but looking back, I think Lola was bored.
That was before I knew all about dog enrichment!
You live and you learn, so now I look out for signs of boredom from Lucy. I noticed she’s been barking a lot more than usual lately. Lucy has always been a vocal dog! But I know her well enough to know that the short, gentle walks we’ve been doing since her diagnosis weren’t enough to keep her mentally stimulated.
By bringing back the busy box in a modified way, I’ve noticed Lucy is:
- More satisfied and happier overall
- Barking less because she doesn’t need to demand I entertain her
- Enjoying the mental stimulation even when physical activity of the box is limited
According to research from the Cornell University College of Veterinary Medicine: “Most older dogs still want to go places and do stuff — especially with you!”
As a Certified Canine Enrichment Technician (DN-CET), I know how how important mental stimulation is for seniors. They physically can’t do as much or go as far, so we need to keep their days fresh and exciting with mental stimulation – that includes puzzles, sniffing, sounds and more!
We’ve been doing busy boxes for over 6 years, so I know this is an enrichment activity that will meet a lot of my senior dog’s needs. I just have to switch things up a bit. Here’s how I do that.

5 Ways I Adjusted the Busy Box Activity for My Senior Dog
1. Select Lower, Flatter Boxes
The first modification I made was selecting a box that was lower to the floor. I didn’t want a big box that Lucy could jump into because that could cause her to hit her belly. With her splenic mass, we want to avoid any belly bumping!
But even if your senior doesn’t have the same condition as Lucy, choosing a different box can help make this activity more accessible to your pup as they age.
Some ideas for making your busy box more senior-friendly:
- Use lower-profile boxes (shoe boxes or the small Amazon box)
- Cut out one side of a box so your dog can access what’s inside without having to stand
- Use box lids for dogs who can’t stand for long periods
- Place the box on non-slip surfaces for stability (yoga mats are a senior dog’s best friend)
2. Keep It Simple, Keep It Fun
Enrichment should always be fun, never frustrating. So I keep that in mind here and simplified our busy boxes significantly:
- I didn’t use any extra containers (unlike my original busy box where I use a few yogurt containers in each box)
- Choose a box that was easier to open
- I now use crinkle packing paper as the filling to make the box interesting but not too exhausting to “solve”
- Lighter materials that are easier to manipulate
Although this was the easiest busy box I’ve even built, I was surprised that my dogs weren’t disappointed by how simple it was.
Both Burt and Lusy were still happy to engage with them, rip them open and find all the treats. It was just in a gentler way than before.
They spent a ton of time sniffing around afterward and checking out each other’s boxes. This was a slower and more gentler version of our old body box mayhem! But that didn’t make it less enjoyable.

3. Treats That Work With Senior Dog Diets
Lucy’s diet has changed since her cancer diagnosis and that’s a big reason we didn’t do busy boxes for a while. She eats home-cooked food that couldn’t be used for this activity. But she still has lots of treats that she can eat!
I use a handful of healthy dog treats to make this activity fun and adapted to her senior dog diet.
If your senior dog is on a special diet, too, try these tips for what to put in their busy box:
- Use freeze-dried raw toppers or treats (I like Only Natural Pet or Stella & Chewy’s Meal Mixers)
- Choose treats that don’t leave crumbs (which can be frustrating if your dog can’t access all the small pieces)
- Opt for softer treats if your dog has dental issues (Zukes are great!)
- Focus on scent-based enrichment if eating is difficult
If your dog is really limited in what they can eat, they don’t have to be left out. Their sense of smell probably still works. Figure out what kinds of scents they like, and you can incorporate that into their box.
Here’s a video where I show you how to use a berry container to safely introduce your dog to interesting tea smells.
Expert Tips to Adapt a Busy Box for Your Senior Dog
A couple of years ago, Bust and Lucy would have crazy busy box sessions where they would jump in their box, fling them around my backyard, and intensely search for every last crumb.
Now, a typical senior busy box session in our home looks different:
- We do this activity indoors instead of in the yard (because it’s easier to find treats on the floor than in the grass)
- Sessions are shorter (5-10 minutes is perfect)
- I use crinkle packing paper inside the box mixed with healthy treats
- I supervise the entire time and help if needed
Remember that enrichment should never be frustrating – it should always be fun! If your dog has decreased capabilities, make sure you’re helping them succeed.

Keeping Your Senior Dog Safe While They Play
Dog enrichment puzzles aren’t a babysitter for your dog, it’s a chance for your dog to bond with you. Therefore, you should always stick around and supervise your dog with their busy box.
Some other specific safety considerations for senior dogs are:
- If your dog has a health condition like Lucy’s splenic mass, avoid activities that could cause bumping or jostling
- For dogs with vision issues, place the box where they can easily see it and show them where it is
- I avoid using plastic tape on the boxes because you don’t want your dog to eat that
- Avoid small pieces that could be choking hazards
- Never use glass containers because they could break
If you notice your dog becoming frustrated with an activity, you can simplify it even further. This can be hard because we get used to doing things a certain way, but adapting to your senior dog’s changing needs is key to their happiness and well-being.
At your dog’s annual wellness checkup, you can chat with your veterinarian about safe activities for your older dog. Plan to reassess your dog’s physical capabilities often.
A dog who wants to please you may push their body beyond ideal limits, so you have to pay attention to their limits.
Lucy doesn’t always understand that she has limits these days. In her mind, she still wants to do everything she used to do. It’s my job to modify our activities and keep her safe.

Think Outside the Box (But Still Use a Box!)
Mental enrichment is so important for your dog to stay healthy longer. Cognitive enrichment is proven to help prevent doggy dementia. But even if you feel your dog already has som signs of dementia, they can still benefit from enrichment activities.
I promise that even if you think your dog loves sitting on the couch all day doing nothing, trying a simplified busy box will engage them in new ways.
Remember, dogs can smell approximately 100,000 times better than we can! So even the box itself may smell interesting to them.
One small way you can enrich your senior dog’s life is to let them inspect all the mail and packages that come into your home.
They might be able to detect all the different people who handled that box and the facilities it traveled through before getting to your home.

My Most Important Lesson for Senior Dog Enrichment
If there’s one thing I’ve learned caring for Lucy through her cancer journey, it’s this: breaking enrichment activities into little baby doses throughout the day works best for seniors.
A 5-minute busy box session is the perfect afternoon activity. –> See this post to learn how much enrichment your dog needs.
Listen to your dog’s needs, not their wishes. Like I said earlier in this post, Lucy would definitely choose to do the extended loop at the park if I let her. But I know a shorter walk keeps her feeling better all day long.
As her parent, I need to look out for her safety and well-being. Smaller activities a few times a day are better than 1 big thing.

Just because your dog is aging or has mobility challenges doesn’t mean they can’t enjoy enrichment! In fact, it’s even more important for their cognitive health and happiness.
