Prep the pineapple. If using fresh, remove the tough core and rind.
Cut into chunks. If using frozen, let it sit for 5–10 minutes to soften slightly.
Blend the base. Add pineapple and plain yogurt to the blender. Blend until smooth.
If it’s too thick to blend easily, add 2–4 tablespoons of water or low-sodium broth.
Tweak the texture. For firmer treats, use Greek yogurt. For a softer, creamier texture, add a spoon of mashed banana or a bit more yogurt.
Add optional boosts. Pulse in shredded coconut or chia seeds. Keep the texture smooth enough to pour into molds.
Pour into molds. Use silicone molds or an ice cube tray.
Leave a little space at the top for expansion as they freeze.
Freeze. Place the molds flat in the freezer for 3–4 hours, or until fully set.
Release and store. Pop out the treats and transfer them to a sealed freezer bag or container. Label with the date.
Serve smart. Offer 1–2 small treats for small dogs, 2–3 for medium, and 3–4 for large dogs. Start with less if your dog is new to dairy.
