Is Egremont Russet Apple toxic to dogs?

Yes — egremont russet apple is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. The fruit flesh is edible and safe, but the ASPCA lists apple (Malus) as toxic to cats, dogs and horses because the stems, leaves and seeds contain cyanogenic glycosides that release cyanide, especially when wilting. Signs of significant ingestion include brick-red gums, dilated pupils, laboured breathing and shock; keep pets from chewing prunings and seeds.

Signs of significant ingestion include brick-red gums, dilated pupils, laboured breathing and shock; keep pets from chewing prunings and seeds. Signs usually appear soon after chewing rather than hours later — watch for drooling, pawing at the mouth, vomiting, loss of appetite, or unusual lethargy after your dog has had access to egremont russet apple.

Stay calm. Remove any plant from your dog's mouth and take the plant away. Note how much was eaten and when, and do not induce vomiting unless told to. Call your vet or the ASPCA Animal Poison Control Center on (888) 426-4435 and follow their advice; a leaf or photo helps the vet treat it correctly.
