Keep all chocolates and candies out of nose reach!
Chocolate contains an ingredient called theobromine which cannot be metabolized by dogs which can lead to toxicity. Symptoms of chocolate ingestion includes: vomiting/diarrhea, increased thirst, panting/restlessness, racing heart rate (tachycardia). In severe cases it can cause a cardiac arrhythmia, muscle tremors and seizures. Symptoms can take a few hours to show and can last for several days.
Another harmful ingredient to animals is Xylitol. This is an artificial sweetener that is found in gum, some peanut butter brands and various candies such as gummies. Xylitol is quickly absorbed into the bloodstream, resulting in a potent release of insulin from the pancreas. This rapid release of insulin causes a profound drop in blood sugar (hypoglycemia), an effect that can occur as quickly as 10-60 minutes after ingestion. If untreated, hypoglycemia can be life-threatening. Symptoms include: Vomiting, weakness/lethargy, lack of coordination/difficulty walking or standing, Tremors, Seizures. Coma.
If you think your pet has consumed either of these products, call poison control immediately and seek veterinary care.
Keep Halloween décor out of reach as curious pets can injury themselves accidently or try to chew on them. This poses a risk of a foreign body that may or may not be able to pass through your pets’ intestinal system. If a blockage occurs this can only be corrected by surgery. Signs of a blockage may include: vomiting/diarrhea (or the opposite! Retching or straining to have a bowel movement), lethargy, painful abdomen. X-rays may be indicated but not all material can be seen on a digital x-ray. Foreign bodies are a medical emergency.
Provide a safe place for your anxious pet
Unless your pet is extremely mellow, let them rest in a room away from the busy front door. Turn on a TV, radio, or white noise machine to dull the sound of the doorbell and exuberant trick or treaters. Or better yet, pre-empt the doorbell by sitting outside and intercepting children before they reach your front door. It also lessens the risk of pets trying to escape outside.
Sedatives can be effective if your pet has sensitivities with loud noises or strangers coming by the house.
