Halloween pet safety

Keep Halloween candy well out of the reach of pets!


Many dogs love the smell and taste of chocolate. In general, the darker and more bitter the chocolate, the more poisonous it is. Symptoms include vomiting, diarrhea, lethargy, agitation, increased thirst, an elevated heart rate and, in severe cases, seizures. Click this link for an informative video on chocolate.

Candy overindulgence

Large ingestions of sugary, high-fat candy can lead to very painful and potentially fatal pancreatitis in pets. It may not show up for two to four days after the pet ingests the candy. Symptoms include decreased appetite, vomiting, diarrhea, lethargy, abdominal pain, and potentially, kidney failure or organ damage.

Grapes and raisins

Mini-boxes of raisins are popular at Halloween. Raisins (and grapes) can cause kidney failure in dogs and, potentially, cats. Symptoms include vomiting, nausea, decreased appetite, lethargy, abdominal pain, and severe kidney failure.

Candy wrappers

Ingestion of foil and cellophane wrappers can cause a life-threatening bowel obstruction, which can require x-rays for diagnosis and surgery to correct. Watch for vomiting, decreased appetite, not defecating, straining to defecate, or lethargy.

Glow jewellery

Glow sticks and glow jewellery contain a chemical which is poisonous to cats. One bite can cause leaking from the glow stick, and cats ingest more and more as they clean the chemical off their fur and paws. Watch for profuse drooling, gagging, retching, pawing at the mouth, redness and irritation of the eyes and/or skin, vomiting. 


Keep candles out of the reach of curious noses and wagging tails. Sometimes pets donít realize something is hot until they get burned.


If your dog barks every time the doorbell rings, Halloween night will be very stressful. Put your dog in a quiet room away from the front door with a radio or television on for background noise. Leave them a new toy or a Kong toy stuffed with dog-safe treats to help provide distraction. Consider using a plug-in diffuser called "Adaptil" that releases a calming pheromone to help relieve anxiety and stress.
