Short answer: steam them. Put the hard treats on a plate, lay a damp paper towel over the top, and microwave for 10-15 seconds. The steam pushes moisture back into the treat and it goes chewy again. Let it cool all the way down before you hand it over. For a bigger batch, cover the treats with foil and warm them at 250°F for 5-10 minutes with a small pan of water on the rack below.
I'm Preston, co-founder of Bully Sticks Central. We get this question constantly, usually from folks with a senior dog or a puppy who suddenly stopped eating a treat they used to love. Here's what actually works, what to skip, and how to keep it from happening again.
Why Do Dog Treats Get Hard in the First Place?
Air. That's most of it. Soft-baked and semi-moist treats hold a fairly high water content, and the second the bag is open, that moisture starts migrating out into the room. Cool, dry air pulls it out faster. What's left is a dense, dry treat that's tough to break down.
The other cause is temperature swings. A bag that sits in a hot garage and then cools overnight will sweat and re-dry repeatedly, which stiffens the treat far quicker than a pantry shelf would.
Worth saying plainly: this only applies to soft or semi-moist treats. Naturally hard chews like bully sticks, tracheas, and beef ribs are supposed to be hard. That firmness is what scrapes the teeth and gives the dog something to work on. Don't try to soften those.
Four Ways to Soften Hard Dog Treats
1. Microwave with a damp paper towel (fastest)
Treats on a microwave-safe plate, damp paper towel draped over them, 10-15 seconds. Check, and add 5 seconds if you need to. Do not walk away and do not run it a full minute — you'll cook the treat dry and you can create hot spots inside it. Always let it cool completely in your hand before your dog gets it.
2. Warm and steam in the oven (best for a batch)
Spread the treats on a baking sheet, cover tightly with foil, and put them in a 250°F oven for 5-10 minutes. Set a shallow pan of water on the rack underneath. The trapped steam rehydrates the whole tray evenly. This is the method I use when a whole bag has gone stiff.
3. Brush with broth or water, then warm
Lightly brush the treats with water or a no-salt-added, onion-free and garlic-free broth, then warm them at 250°F for a few minutes. This one adds flavor along with the moisture, which helps if the dog has gotten bored of the treat. Skip any broth containing onion or garlic — both are toxic to dogs, per the ASPCA.
4. The bread-slice trick (passive)
Drop a slice of plain bread into the airtight container with the treats. Over a day or so, moisture migrates from the bread into the treats. Swap the slice every couple of days and pull it the moment you see any discoloration. An apple slice works the same way. This is the slowest method but it takes zero effort.
Is It Safe to Rehydrate Old Dog Treats?
Softening a dry treat is fine. Reviving a spoiled one is not, and adding moisture to a treat that's already turned is a good way to grow mold and bacteria in it. Toss the treat instead of softening it if you see any fuzz or discoloration, if it smells sour or rancid, if it's oily or slimy to the touch, or if it's past the date on the bag.
Once you've added moisture back in, treat it like fresh food: use it within a day or two, and refrigerate anything you don't use. The FDA's guidance on handling pet food and treats is worth a read — wash your hands and the plate afterward, same as you would with raw ingredients.
What If Your Dog Stopped Eating Hard Treats Altogether?
This is the part people skip. If a dog who happily crunched treats last month is now refusing them, dropping food, chewing on one side, or pawing at their mouth, softening the treat is treating a symptom. Periodontal disease is extremely common in adult dogs, and VCA Animal Hospitals notes that the majority show signs of it by age three. Get the mouth looked at. The AKC's dental care guidance covers what to watch for at home.
Same goes for puppies in the middle of teething — sore gums are the reason, not the treat.
How Do You Keep Dog Treats From Drying Out?
Leave the treats in their original bag, then put that bag inside an airtight container. The original packaging is built with a moisture barrier; a plastic tub alone usually isn't. Squeeze the air out before you seal it, keep it out of the garage and off the windowsill, and buy smaller bags if a big one always goes stale before you get through it.
Honestly, the simplest fix is buying chews that were never soft to begin with. Everything we make at Bully Sticks Central is single-ingredient and 100% real meat — 100% natural, fully digestible, no rawhide, and ethically sourced from grass-fed American and Argentinean farms. A dry-cured chew has almost no water in it to lose, so it doesn't go stale on you the way a soft-baked biscuit does. It just sits in the jar until your dog wants it.
If you're rethinking what's in the treat jar, start with our guide to single-ingredient dog chews, and if you want something with more give than a bully stick, beef trachea is lighter and easier on an older mouth. For dogs who want something softer and flavored, our take on peanut butter treats covers what to look for on the label.
Everything we sell is 100% high-quality guaranteed. If a bag ever shows up and isn't right, email us and we'll make it right.
