Pet Costume Safety Tips.

While pet parents are excited to slip an adorable costume on furry friends, the pets themselves may be more reluctant. It’s important to remember a pet’s comfort and safety first. Here are a few important tips from Wondercide:

1. Avoid costumes that block a pet’s vision, hearing, movement or cause discomfort. If the costume includes face or ear coverings, slip them on for a quick photo opportunity and remove it after the picture.

2. If a costume comes with small pieces they could be choking hazards. Curious animals naturally want to sniff things and might chew or swallow pieces of a costume.

3. Make sure costumes fit properly and aren’t too tight (limiting breathing, eating, drinking or pet movement). When making a costume try to use soft material that won’t irritate a pet’s coat or fur. Make sure pets don’t get too cold, overheated or dehydrated during all the fun.

4. When welcoming trick or treaters or walking around the neighborhood, keep the pet’s temperament in mind. Scary masks, bright lights, new sounds and a lot of activity can cause pet anxiety.

5. When out and about trick-or-treating or parading, be on alert for the scariest monsters in the neighborhood: bugs. Fall is a prime time for creepy crawlers such as ticks, fleas, and mosquitos to hunt their prey. Due to the damp seasonal climate, these bugs thrive this time of year, causing outdoor activities to become a little less enjoyable. Protect pets and family with products like Wondercide’s Insect Repellent for the family and Flea and Tick Spray for pets to combat the real creepy crawlies.

6. Lastly, make sure candy is stored out of pets reach especially treats that contain chocolate which can be poisonous to pets. 

Gear up with us and celebrate all that October offers. Wonderween is the perfect way to get the family together, be creative, and have fun. Whether you aim for a unique take on a classic costume or invent your own look, you’re in for a pawsome Wonderween!
