Is Pecan 'Cape Fear' toxic to dogs?

Mildly. The ASPCA lists pecan 'cape fear' as mildly toxic to dogs — a chewing dog typically gets mouth irritation, drooling, and vomiting rather than a medical emergency, but it is still best kept out of reach. The ASPCA lists related hickories such as water hickory/bitter pecan (Carya aquatica) as non-toxic, and pecan foliage is not classed among toxic plants. However, pecan nuts contain juglone and the high-fat kernels readily develop mold harbouring tremorgenic mycotoxins and aflatoxin, which can cause gastrointestinal upset, tremors, seizures and pancreatitis in dogs. Keep fallen and moldy nuts away from pets and verify with a vet if ingested.

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 pecan 'cape fear'.

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 in the US, or Animal PoisonLine on 01202 509 000 in the UK and follow their advice; a leaf or photo helps the vet treat it correctly.
