Are Red Delicious apples safe for dogs?

Yes. Red Delicious flesh and skin are non-toxic per the ASPCA. The variety carries roughly 11.6g sugar per 100g and 52 kcal per 100g, both mid-range for common varieties. The defining feature is a notably thicker, more leathery skin than other varieties, which adds fibre and requires more chewing.

Should I peel Red Delicious before giving to my dog?

For most adult dogs, no. The skin is the main carrier of dietary fibre and polyphenol antioxidants. For very small breeds (under 5kg), dogs with sensitive stomachs, dogs with a history of loose stool from fibre, or dogs that struggle to chew, peeling Red Delicious specifically can be useful because the skin is the thickest of common varieties.

The short answer

Red Delicious apples are safe for dogs. Same non-toxic classification as any apple per the ASPCA. The one practical quirk: Red Delicious skin is notably thicker than other supermarket varieties, which adds fibre and choking material. For most adult dogs this is irrelevant. For small breeds, peeling is a reasonable habit. The flesh is mid-range sweetness at roughly 11.6g sugar per 100g.

The thicker skin: why it matters and why it usually does not

Red Delicious was selected over a century of commercial breeding for shipping resilience, supermarket appearance and shelf life. Those selection pressures favoured a tough, leathery skin that resists bruising during transport and storage. The result is the variety's defining textural characteristic: skin perceptibly thicker and waxier than Gala, Honeycrisp or Granny Smith.

For dogs, that has two implications. First, the skin carries proportionally more insoluble fibre per gram than thinner-skinned varieties. For most adult dogs that is a small benefit: extra fibre supports healthy bowel movement and gut microbiome diversity. For dogs with sensitive stomachs, fibre overload causes loose stool. Reduce portion or peel.

Second, the skin is harder to chew. Small breeds with shallower bite force may swallow Red Delicious skin in larger fragments than they would Gala skin. In practice, this is a marginal risk: dogs do not aspirate apple skin in any meaningful frequency. But for toy breeds under 5kg, peeling Red Delicious specifically is a sensible habit even though peeling other varieties is unnecessary.

Why Red Delicious appears in so many lunchbox apples

Red Delicious dominated US apple production from the 1960s to the 2010s. The variety's extreme storage tolerance and visual appeal made it the default supermarket apple for decades. US Apple Association data records the variety's peak market share in the late 1990s. Since 2018, Gala has overtaken Red Delicious as the top US variety, and Honeycrisp, Fuji and Cosmic Crisp continue to gain share.

Why this matters for treat-feeding: Red Delicious in the kitchen is often older than Honeycrisp from the same shop, because Red Delicious can hold quality longer in storage. An older apple is not unsafe but may carry less polyphenol content than a fresher harvest. The variety's reputation among adult human eaters has declined as fresher, sweeter alternatives became available; for a dog, the variety is fine, and discounted Red Delicious in autumn or early winter is often the best value way to keep apple as a routine treat.

Fibre math: skin on vs skin off

A 20g slice of Red Delicious with skin contains roughly 0.5g dietary fibre. The same slice peeled contains roughly 0.3g. Across a 1.5 daily slice typical small-dog portion, that is a difference of 0.3g fibre per day. For most dogs that is well below the threshold that affects stool quality. For a dog already at the high end of fibre intake (heavy-fibre kibble plus other plant treats), 0.3g extra can push the system toward loose stool.

Portion	Skin on	Skin off	Practical implication
Half slice (10g)	~0.25g fibre	~0.15g fibre	Negligible difference
1 slice (20g)	~0.5g fibre	~0.3g fibre	Negligible for most dogs
2 slices (40g)	~1.0g fibre	~0.6g fibre	Noticeable for fibre-sensitive dogs
3 slices (60g)	~1.5g fibre	~0.9g fibre	Peel if loose stool history
1 medium apple (200g)	~5.0g fibre	~3.0g fibre	Most dogs should not have this much daily

Pesticide and waxing concerns specific to Red Delicious

Commercial Red Delicious are routinely waxed post-harvest to improve appearance and extend shelf life. The waxes used are food-grade (carnauba, shellac, candelilla) and considered non-toxic by the US FDA. They are not removed by water rinse alone. The Environmental Working Group's Dirty Dozen consistently places apples in the top ten produce items for pesticide residue.

A baking-soda soak (1 teaspoon per cup of water, 12-15 minutes) is more effective than water alone at removing surface pesticide and wax. A 2017 study published in the Journal of Agricultural and Food Chemistry tested standard wash methods against thiabendazole and phosmet on apples; baking-soda water outperformed bleach and water-only washes. Organic Red Delicious avoid the synthetic pesticide load but may still carry waxes (food-grade) and require the same wash treatment.

When in doubt, consult your veterinarian

If your dog has any history of food intolerance, fibre sensitivity, or unexplained loose stool, raise apple treats at your next vet visit before establishing them as routine. A vet who knows your dog's GI history can suggest whether peel-on or peel-off, and what portion size, is sensible.

The seeds and core

Same as any apple variety. Red Delicious seeds contain amygdalin (Merck Veterinary Manual), the core is a choking and obstruction risk. Remove both before serving. Full breakdown on the core and seeds page.

Frequently asked questions

Can dogs eat the wax on Red Delicious apples?+

In trace amounts, yes; the food-grade waxes used commercially are non-toxic. Better practice is to wash with a baking-soda soak before serving any commercially grown apple. The wax serves no nutritional purpose and adds nothing the dog needs.

Are Red Delicious apples lower quality than other varieties?+

Lower commercial popularity, not lower safety. Modern eaters prefer Honeycrisp, Gala and Fuji for taste; Red Delicious lost market share for that reason. For a dog who does not distinguish between variety sweetness, Red Delicious are fine and often cheaper.

Why is Red Delicious skin so much thicker?+

Decades of commercial breeding selected for skin that resists bruising during long shipping. The variety dominated US production specifically because growers could ship it across the country without quality loss. The thicker skin is a side effect of that selection.

Can puppies eat Red Delicious apples?+

Yes, but peel them first. Puppy chewing is less efficient than adult chewing, and Red Delicious skin requires more force to break down. Peeling removes the choking concern entirely; the puppy still gets the flesh nutrition. Cube to 1cm pieces, start with a single sliver.
