Is Damson 'Merryweather' toxic to dogs?

Yes — damson 'merryweather' is toxic to dogs according to the ASPCA. Keep it well away from any dog that chews plants; reactions can be significant. Prunus insititia is part of the Prunus genus, which the ASPCA lists as toxic to dogs, cats and horses (Plum and Cherry entries). The leaves, stems and stones contain cyanogenic glycosides that release cyanide when chewed, causing brick-red gums, dilated pupils, laboured breathing, panting and shock. The ripe flesh is eaten by people, but pits and foliage are hazardous to pets.

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 damson 'merryweather'.

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.
