Ingredients You’ll Need
This recipe uses just one simple, dog-safe ingredient.
Main Ingredient
- Fresh apples
That’s it no oil, no sugar, no seasoning.
💡 Choose firm, sweet apple varieties like Fuji, Gala, or Honeycrisp for best results.
Equipment Needed
- Knife or apple slicer
- Cutting board
- Baking tray
- Parchment paper or wire rack
- Oven
Step-by-Step Instructions
Step 1: Preheat the Oven
Preheat your oven to 225°F (105°C). Line a baking tray with parchment paper or place a wire rack on top of the tray for better airflow.
Step 2: Prepare the Apples
Wash the apples thoroughly. Peel if desired (peeling makes them easier to digest, but leaving the skin on is fine if well cleaned).
Remove the core and all seeds. Slice the apples into thin, even slices about ⅛ to ¼ inch thick.
Uniform thickness helps the slices dry evenly.
Step 3: Arrange on the Tray
Place apple slices in a single layer on the prepared baking tray. Make sure slices do not overlap, as airflow is important for drying.
Step 4: Oven-Dry the Apple Slices
Place the tray in the oven and bake for 2½–3 hours, flipping the slices halfway through.
- Thinner slices = crunchier results
- Thicker slices = slightly chewy texture
Keep the oven temperature low to dry the apples slowly without browning.
Step 5: Cool Completely
Remove the apple slices from the oven and allow them to cool completely on the tray. They will continue to crisp up as they cool.
Never give warm apple slices to your dog.
How to Know When They’re Done
Oven-dried apple slices should be:
- Dry to the touch
- Firm with slight flexibility
- Free from moisture in the center
If slices feel soft or moist, return them to the oven for an additional 15–30 minutes.
Serving Size Guide
Even healthy treats should be fed in moderation.
- Small dogs: 1–2 small slices
- Medium dogs: 2–3 slices
- Large dogs: 3–4 slices
Treats should stay within 10% of your dog’s daily calorie intake.
Storage Tips
Proper storage keeps apple slices fresh and safe.
- Store in an airtight container
- Keep at room temperature for 1–2 weeks
- Refrigerate for longer freshness
- Freeze for up to 3 months
If you notice moisture or mold, discard immediately.
Common Mistakes to Avoid
- ❌ Leaving seeds or core in the slices
- ❌ Using high oven temperatures
- ❌ Adding sugar, cinnamon, or seasoning
- ❌ Storing slices before fully cooled
Are Oven-Dried Apple Slices Safe for Puppies?
Yes, when:
- Cut into small pieces
- Dried thoroughly
- Given in moderation
For puppies, offer thinner or slightly chewy slices to make chewing easier.
Easy Variations to Try
Once you’re comfortable with this method, you can also oven-dry:
- Apple rings (core removed, left whole)
- Apple chips (very thin slices)
- Apple–pear slices (prepared separately)
Always introduce new treats gradually.
Final Thoughts
These Oven-Dried Apple Slices are crunchy, naturally sweet, and incredibly easy to make. They’re a perfect example of how simple, single-ingredient treats can still be exciting and satisfying for dogs.
