Halloween is all about candy, tricks, and costumes. But for many dogs, it can be an evening full of confusion, strong smells, and unpleasant noises. What feels festive to us can be both stressful and dangerous for a dog. Here are a few things to keep in mind to make the evening safe and cozy for your four-legged friend too.

🍫 Chocolate is worse than you think

Most people know that dogs shouldn’t eat chocolate. But few realize how little it actually takes to become dangerous. Chocolate contains the substance theobromine, which dogs can’t break down. Even small amounts can cause vomiting, restlessness, and heart problems. Keep all candy stored up high, preferably in a container with a lid. Your dog can find more than you think.

🍬 Sugar-free doesn’t mean safe

Many sugar-free candies and chewing gums contain xylitol. This can cause a rapid drop in blood sugar and damage a dog’s liver. Just one piece can be enough to make a dog seriously ill. Check what you have at home and keep it well out of reach.

🕯️ Pumpkins and decorations can cause trouble

A lit pumpkin on the floor looks nice but can easily be knocked over if a curious dog gets too close. The same goes for decorations with small parts, glitter, and plastic ribbons. Dogs love to chew on anything they find. If you want that cozy atmosphere, choose battery-powered candles and decorate in places your dog can’t get to.

😱 Costumes and masks can be scary

Dogs recognize people by their scent, voice, and movements. When you suddenly show up wearing a mask or strange clothes, it can make them feel insecure. Let your dog see and sniff the costume before you put it on. If a lot of people are coming over, give your dog a quiet space where it can be left alone.

🚪 Lots of activity at the door

On Halloween evening, the doorbell often rings over and over. Children in costumes laugh, shout, and run around. For a dog, this can be overwhelming. It’s a good idea to keep your dog in another room with some music or the TV on in the background. That makes it easier for them to relax and reduces the risk of them slipping out when the door opens.

🧡 A safe and fun evening

Halloween can absolutely be a cozy evening for dogs too, as long as you plan a little. Avoid dangerous treats, check your decorations, and make sure your dog feels safe when things get busy. That way, you can both enjoy the evening in your own way.
