Halloween and La Castañada are two eagerly awaited celebrations in autumn. While we enjoy pumpkins, costumes, chestnuts, and panellets, our cats and dogs may experience these holidays very differently. Noises, unexpected visitors, changes in routine, or the presence of unusual decorations can become stressors that affect their physical and emotional well-being.
In this article, you will find a practical guide to learning how to recognize the signs of fear and anxiety in your furry friend during these celebrations, as well as tips to help them feel safe at home. We will also explain which foods and decorations pose the most common risks during this time of year and what to do in case of poisoning or accidents, so you can enjoy Halloween and La Castañada with peace of mind alongside your pets.
At Balmesvet, we know that identifying the early signs of stress and knowing how to prevent it is essential for protecting your pet’s health and avoiding any unnecessary surprises.
Stress in dogs and cats during Halloween and Castañada: how to recognize it
Signs of stress in dogs
Dogs often show their discomfort with visible changes in their behavior and body language:
- Excessive panting, even when at rest. Restlessness, pacing, or attempting to escape.
- Trembling or constantly seeking out their guardian.
- Compulsive licking of paws or other areas of the body.
- Continuous barking or unusual whining.
Signs of stress in cats
Cats, which are more discreet, tend to express stress differently:
- Hiding in high or inaccessible places.
- Ears back, stiff tail, or sudden movements.
- Excessive meowing or, conversely, sudden silence.
- Refusal to eat or changes in litter box use.
- Vomiting or diarrhea resulting from anxiety.

Stress and health in pets: effects beyond behavior
Stress is not only reflected in behavior, it can also affect the body. Both dogs and cats can suffer from digestive problems, lowered immune defenses, or aggressive behavior if fear is not managed in time. Early detection is key to preventing the situation from worsening.
How to help your dog or cat feel safe on Halloween and Castañada
- Create a quiet refuge: prepare a room where they can retreat with familiar objects (blanket, bed, toys).
- Use calming pheromones and relaxing music: these help reduce anxiety and create a calm environment.
- Keep routines stable: keep walks and feeding times as close to normal as possible.
- Don’t force interactions: if they prefer to hide, respect their space.
- Be careful with costumes: avoid dressing them up if they show signs of discomfort; a bandana or light accessory is enough. If you want more recommendations, here are our tips for dressing up your pets safely.
In cases where fear or anxiety are severe, it is best to consult with a veterinarian. There are pharmacological support options or tailored therapies available to ensure your cat or dog does not suffer during the holiday season.
Prevention of poisoning and accidents during Halloween and Castañada
In addition to stress, these holidays bring other risks: accidental ingestion of food or contact with items that may be toxic or dangerous to animals. Knowing which products to keep out of their reach and how to act in an emergency is essential for avoiding complications.
Risky foods for dogs and cats during Halloween and Castañada
- Chocolate and sweets: these contain theobromine and, in some cases, xylitol, both of which are very dangerous for dogs and cats. Even small amounts can cause serious poisoning.
- Chestnuts: although not toxic, they can cause choking or intestinal blockages.
- Panellets: made with sugar, almonds, pine nuts, or chocolate, all of which are unsafe ingredients for our furry friends.
- Raw sweet potatoes: difficult to digest and potentially irritating. They can only be eaten when well cooked, in small quantities, and without seasoning.
The safest thing to do is to only give your canine or feline companion snacks that are specifically formulated for them, avoiding any experimentation with human food. It is important that you read this article on foods that are prohibited for your pet.
Dangerous fall decorations: pumpkins, candles, wires, and small ornaments
- Pumpkins: decorative or natural pumpkins in poor condition can ferment and cause digestive problems.
- Candles and incense: risk of burns, respiratory poisoning, or accidental ingestion.
- Electric lights and garlands: chewing on the wires can cause electrocution or serious injury.
- Small decorations: if swallowed, they can cause choking or intestinal blockages.
What to do in case of poisoning or accident: emergency steps and when to go to the vet
- Stay calm and remove the product so that your pet cannot ingest it again.
- Do not induce vomiting without the advice of a veterinarian, as in some cases this can make the situation worse.
- Call an emergency veterinarian immediately and provide as much information as possible (what they ate, how much, how long ago, product packaging).
- Go to the hospital as soon as possible; speed is key to avoiding serious complications.
