The Pupsicle — the freezable treat-ball toy that has become its own search category in 2026 (27,100 monthly searches, up 83% year on year, per risingtrends.co) — is genius: pop a frozen refill inside, hand it to your dog, and you get 20–30 minutes of quiet licking. The catch is the official refill packs. They work, but they cost real money over a month of daily use, and you have zero say over what is inside them.
Homemade pupsicle refills solve both problems. You control every ingredient, each refill costs pennies, and you can tune the recipe to your dog — low-calorie for the dog on a weight plan (see our dog weight loss food plan), extra-aromatic for the picky eater (see our best dog food for picky eaters guide), or novel-protein for the sensitive stomach (our sensitive-stomach guide covers the approach).
The concept is simple: blend a dog-safe mixture, freeze it into the shape your toy takes (most Pupsicles use a round ball or disc cavity), pop it in, done. Below are the ground rules, then seven refill recipes worth rotating.
For more frozen ideas, see our lick mat recipes for dogs (the same mixtures work on lick mats) and our homemade teething treats for puppies — several of those doubles as pupsicle refills.
The ground rules for DIY refills
A refill is a frozen treat, not a meal. Four rules keep it safe:
- Xylitol is the killer. Some peanut butters and “sugar-free” yoghurts contain xylitol (also labelled birch sugar), which is toxic to dogs in tiny amounts. Read every label before it goes in the blender.
- Budget the calories. Treats and toppers together stay under 10% of daily calories. A medium dog on 800 kcal a day gets ~80 kcal of treats — one modest pupsicle refill, not three.
- Freeze solid, thaw the surface. Freeze refills for at least 4–6 hours (overnight is safest). Run the frozen ball under warm water for 5 seconds before loading — it slides in easily and the surface softens a touch.
- Supervise, always. The toy is durable; the refill is food. Take the toy up when the refill is gone, and retire any toy with cracks or chewed edges.
Hard no’s in every refill: chocolate, grapes, raisins, macadamia nuts, onion, garlic, alcohol, coffee, and anything sweetened with xylitol.
1. Classic peanut butter banana
The crowd-pleaser and the cheapest refill on this list. Use plain peanut butter (peanuts + salt only — no xylitol, no palm oil) and ripe banana.
Make it: mash one ripe banana with 2 tablespoons of peanut butter and 60 ml of plain water or unsweetened yoghurt. Press into a silicone muffin tray or round ice-cube mould, freeze 6+ hours. One ball per session for a medium dog.
Good for: first-timers (high acceptance rate), picky dogs. Watch: calorie-dense — peanut butter is ~95 kcal per tablespoon, so measure, do not eyeball.
2. Pumpkin-yoghurt layers
The pretty one — orange and white stripes that look like a proper store-bought refill. Plain canned pumpkin (100% pumpkin, not pie filling) plus plain unsweetened yoghurt.
Make it: whisk 100 g pumpkin purée with 2 tablespoons yoghurt; separately, whisk 100 g yoghurt with a drizzle of honey (a teaspoon — optional). Pour alternating layers into the mould and freeze between layers for crisp stripes. Fibre-rich, easy on digestion.
Good for: dogs with touchy stomachs, Instagram-worthy refills. Watch: yoghurt must be plain and unsweetened — flavoured yoghurts hide sugars and sometimes xylitol.
3. Chicken broth savoury pop
For dogs that turn up their nose at sweet things: a savoury, meaty refill. Plain homemade chicken broth — no onion, no garlic, no stock cubes — plus shredded chicken.
Make it: warm 150 ml plain broth, stir in 50 g of shredded cooked chicken, pour into moulds and freeze. Add a few kibble bits into the mixture before freezing for a crunchy surprise layer. Our bone broth for dogs guide has the safe recipe.
Good for: seniors who prefer softer food, dogs recovering from illness, protein motivation for training. Watch: store-bought “broths” frequently contain onion or garlic powder — read the label or make your own.
4. Blueberry coconut dots
The antioxidant refill. Blueberries are a safe, low-calorie fruit dogs tend to love; unsweetened coconut flakes add texture.
Make it: blend 80 g blueberries with 100 ml plain yoghurt until mostly smooth. Stir in a tablespoon of unsweetened coconut flakes, pour into moulds, freeze. Tart, bright, and only a few dozen calories per ball.
Good for: calorie-conscious dogs (see our dog weight loss food plan), hot days. Watch: blend well for small dogs — whole blueberries are a mild choking shape for tiny mouths.
5. Sardine & sweet potato
The omega-3 powerhouse. Sardines packed in water (not oil, not brine) plus cooked mashed sweet potato — a savoury refill with real nutrition credentials, echoing our salmon oil for dogs routine.
Make it: mash 2 water-packed sardines with 100 g cooked sweet potato (no skin), thin with 2 tablespoons warm water, freeze in moulds. Smelly to make, irresistible to dogs.
Good for: coat and skin support, extremely picky eaters (few dogs refuse fish). Watch: twice a week at most — fish is rich, and variety beats volume.
6. Apple-oat mush
The breakfast refill. Unsweetened apple sauce (or one grated apple, no seeds) plus cooked plain oats — gentle, fibrous, filling.
Make it: stir 100 g unsweetened apple sauce into 80 g cooked oats, add a pinch of cinnamon (Ceylon cinnamon, a pinch only — cassia in quantity is not ideal), freeze. Soft texture, easy lick.
Good for: senior dogs, dogs that like mild flavours. Watch: apple seeds contain amygdalin — grate around the core or use sauce. No cinnamon “doses” — a pinch for aroma, not a spoonful.
7. Surprise-centre broth ball
The enrichment refill — plain broth frozen around a hidden centre. The centre makes the dog work through the layers instead of licking it flat in ten minutes.
Make it: fill moulds one-third with plain broth, freeze 2 hours. Drop a small smear of peanut butter or a single blueberry in the centre, top up with broth, freeze overnight. The frozen shell melts into the surprise.
Good for: fast eaters, clever dogs that demolish simple refills too quickly (pairs with our slow feeder dog bowls strategy), rainy-day boredom. Watch: keep the centre small — it is a flavour reward, not a second meal.
How to fit and store your refills
Match the mould to your toy: round silicone ice-cube trays fit most ball-style toys; if yours takes a disc, freeze in a shallow ramekin. Pop frozen refills into a labelled freezer bag — they keep 2–3 months, and you can batch a month’s worth in one Sunday session.
Fridge rule for mixtures: any unfrozen mixture keeps 3 days refrigerated; once frozen, use within 3 months. If a refill looks freezer-burned or smells off, it goes in the bin, not the toy.
One more trick: freeze a thin broth “shell” in the mould first, then press your main mixture in. The shell gives a harder first layer that slows power-lickers down — the same idea behind our frozen enrichment treats.
When NOT to hand over a frozen refill
Frozen treats are safe for most dogs, but check with your vet first if:
- Your dog has pancreatitis history (or is a prone breed like miniature schnauzers): even modest fat additions can trigger a flare — stick to broth and pumpkin refills.
- Your dog has dental fractures or worn teeth: very hard frozen blocks can crack teeth. Soften the surface under warm water and supervise closely.
- Your dog is on a therapeutic diet (kidney, urinary, allergy, weight-loss): frozen extras can unbalance a precision diet. Clear it with the vet.
- Puppies under 12 weeks: their nutrition is exact; ask the vet before adding frozen extras.
And never leave a dog unattended with a frozen refill — not because the food is dangerous, but because enthusiastic chewers can break chunks off faster than you expect.
FAQs
What exactly is a Pupsicle?
It is a freezable treat-dispensing ball toy: you freeze a ball-shaped treat (the “refill”), pop it into the toy’s cavity, and the dog licks and works at it. The DIY versions here fit any similar freezable ball toy, not just the branded one.
Can I use these mixtures on a lick mat?
Yes — every recipe here doubles as a lick-mat spread. See our lick mat recipes for mat-specific ratios (thinner mixtures spread better).
How long should a refill take my dog?
A well-frozen ball in the toy typically lasts 15–30 minutes of licking for a medium dog. If yours finishes in five, freeze harder (overnight, colder setting) or use the surprise-centre technique.
Are frozen treats bad for dogs’ teeth?
Frozen food itself is fine; the risk is biting hard on a rock-solid block. Run the refill under warm water for a few seconds before loading and supervise — licking is the goal, not crunching.
Can puppies have pupsicle refills?
From about 12 weeks, yes, in small amounts — broth, pumpkin and banana mixtures are the gentlest starters. Teething puppies especially love them (see our teething treats). Very young puppies should get vet clearance first.
How many refills can my dog have per day?
One per day is the sensible ceiling for most dogs, and it must fit inside the 10% treat-calorie budget. A pupsicle refill is enrichment, not a meal replacement.
The bottom line
Homemade pupsicle refills are the rare win-win: cheaper than store packs, fully under your control, and endlessly customisable to your dog. Batch a month’s worth on a Sunday, freeze them in silicone trays, and the daily 20 minutes of quiet licking costs you almost nothing. Start with peanut butter banana or the broth ball, keep it under 10% of daily calories, and rotate the seven recipes here — your dog’s enrichment routine just got an upgrade.
