Halloween Hazards Can Put Senior Pets at Risk, Virginia Animal Welfare Advocates Warn

Halloween brings costumes, candy, decorations, and plenty of excitement, but for older cats and dogs, the holiday can also bring unexpected dangers.

With Halloween approaching on October 31, animal welfare advocates in Upperville, Virginia, urge pet owners to take extra precautions, especially when caring for senior animals that may be more sensitive to stress, routine changes, and potential health hazards.

The advice comes from Cats & Dogs: Senior Wellness, a new educational initiative developed by scientist, entrepreneur, author, and animal welfare advocate Sandy Lerner and veterinarian Dr. Thomas P. Burgess, who has more than 50 years of clinical experience.

Their goal is to help pet owners better understand aging animals’ needs, recognize warning signs of illness, and make informed decisions about veterinary care.

Although Halloween may seem harmless, common holiday activities can pose additional challenges for older pets.

Halloween Candy Can Be Dangerous

One of the greatest concerns is candy, particularly chocolate and sugar-free sweets.

Chocolate contains substances that can be toxic to both dogs and cats, with dark chocolate and baking chocolate presenting especially serious risks.

Sugar-free candies and chewing gum may contain xylitol, a sweetener that can cause a dangerous drop in blood sugar and potentially life-threatening complications in dogs.

The U.S. Food and Drug Administration warns that xylitol poisoning can develop quickly and may cause vomiting, weakness, difficulty walking, seizures, and even liver failure.

Candy wrappers also pose hazards. Pets that swallow wrappers or packaging materials risk choking or developing an intestinal blockage.

Pet owners should keep candy bowls, trick-or-treat bags, and leftover sweets in secure locations where animals cannot reach them.

If a pet eats chocolate, xylitol, or another potentially toxic substance, owners should contact a veterinarian or animal poison control service immediately rather than waiting for symptoms to appear.

Costumes Aren’t Always Fun for Pets

Dressing pets in costumes has become a popular Halloween tradition, but not every animal enjoys wearing one.

Costumes may be especially uncomfortable for senior dogs and cats.

Older animals with arthritis, joint stiffness, or mobility problems may find costumes restrict movement or make it hard to walk comfortably.

Poorly fitted outfits can also interfere with breathing, vision, or normal movement. Loose pieces and decorations may become choking hazards if chewed or swallowed.

Pet owners should watch for signs of discomfort, including attempts to remove the costume, reluctance to move, or unusual behavior.

If an animal becomes uncomfortable or frightened, skipping the costume may be the safest choice. A simple festive collar or bandana may be a better option, provided the pet is comfortable wearing it.

A Quiet Room Can Make a Big Difference

Halloween can also overwhelm animals sensitive to unfamiliar noises and activity.

Repeated doorbell ringing, excited children, visitors in costumes, and frequent door opening and closing can create a stressful environment.

Senior pets with reduced vision, hearing difficulties, or age-related cognitive changes may become confused or frightened by the disruption.

Experts recommend providing a quiet, familiar space away from the front door where pets can rest comfortably.

Keeping favorite bedding, toys, and fresh water nearby can help maintain a sense of security.

Owners should also watch for signs of anxiety, including excessive panting, pacing, trembling, hiding, or changes in behavior.

For older animals, don’t automatically dismiss those symptoms as simple nervousness. Unusual behavior may sometimes indicate an underlying medical problem that needs veterinary attention.

Prevent Escapes and Watch Decorations

Frequent trick-or-treat visits also increase the chance that a frightened pet could slip through an open door.

Keeping animals safely secured in another room can help prevent an accidental escape.

Pet owners should also make sure identification tags and microchip contact information are current.

Halloween decorations create additional concerns.

Electrical cords, small decorative objects, candles, and glow sticks can all present risks to curious pets.

Open flames can cause burns or fires if a pet knocks over a candle or jack-o’-lantern. Battery-operated candles offer a safer alternative.

Owners should also keep electrical wires and small decorations out of reach so pets cannot chew or swallow them.

These precautions can reduce the chance that a holiday celebration turns into a veterinary emergency.

Understanding the Needs of Aging Pets

For Lerner and Burgess, Halloween safety is one example of a larger concern: helping owners recognize how their animals’ needs change with age.

As veterinary care, nutrition, and preventive medicine improve, many cats and dogs are living longer. Those extra years can bring special challenges, including mobility problems, appetite changes, chronic illnesses, and behavioral changes.

“Good senior pet care begins with knowledge,” Lerner said.

“We want pet owners to understand what is normal as their animals age, how to recognize warning signs early and make thoughtful decisions about their pets’ health.”

Lerner said the initiative also aims to help families manage the financial decisions that often accompany veterinary care.

“Our focus is on maintaining senior pet health through good wellness care, spending veterinary dollars wisely and ensuring the human-animal bond is enriched throughout the later stages of a pet’s life.”

Burgess emphasized that knowing when an animal needs medical attention is key to responsible pet ownership.

“Preventive care and knowing when to seek veterinary attention are essential components of responsible senior pet ownership,” Burgess said.

“Not every change in an aging pet requires expensive intervention, but some symptoms should never be ignored. Understanding the difference can improve outcomes for pets and help owners make better-informed decisions about veterinary care.”

That approach encourages pet owners to stay attentive without assuming every age-related change requires extensive or costly treatment.

It also reinforces the importance of maintaining a relationship with a veterinarian who understands an individual animal’s health history and needs.

New Senior Pet Wellness Resource Coming in 2027

Lerner and Burgess are preparing to launch Cats & Dogs: Senior Wellness, a comprehensive resource book and online educational platform, in January 2027.

The project provides practical, research-based information on caring for aging cats and dogs.

Topics will include nutrition, mobility, preventive care, behavioral changes, common age-related medical conditions, treatment decisions, and quality-of-life considerations.

The initiative includes more than 3,000 bibliographic references to help owners better understand veterinary research and available treatment options.

The goal is not to replace professional veterinary advice, but to help owners ask better questions, recognize possible health concerns, and work more effectively with their veterinarians.

Advance orders are being accepted at www.catsanddogsseniorwellness.com.

As Halloween approaches, Lerner and Burgess hope pet owners will remember that a little preparation can make a meaningful difference, particularly for animals in their later years.

Keeping candy out of reach, providing a peaceful environment, avoiding uncomfortable costumes, and watching for unusual behavior are simple steps that can help protect aging companions.

For families who have shared many years with a beloved cat or dog, these precautions are another way to keep their pets safe, comfortable, and included in family life.
