Will My Dog Like Costumes?

Dressing your pup up as the latest pop culture icon may be one of the greatest joys of the holiday season, but if it causes your pup stress, it’s not worth it. The key is finding the right type of costume that properly fits. Add in some fun training, and your pup will be ready to show off their inner unicorn…for at least long enough for you to take a picture.

Finding the Right Type of Unicorn Dog Costume

Every year my husband dreams up elaborate holiday card ideas that involve multiple pet costumes, set design, and all four fur-kids sitting still for long enough for us to take a picture. I love his optimism, but our best success has been finding a simple costume piece for each pet. More importantly, the type of costume piece has to be custom to their wardrobe sensibilities. There are a few standard components to pet costumes, and depending on your dog’s demeanor and body type, you can find something that works for them. Typically there are headpieces, body wraps, bandanas, or collar/leash combos.

My pup Scout wore thunder vests when she was a puppy so she loves wearing a costume that wraps around her body. Some dogs prefer to wear headgear but do not want anything wrapped around their stomach. If both the head and body gear stress out your pup, they will still look majestic in a festive bandana or collar/leash combo.

No one knows your pup better than you. If they are a chewer, avoid any costumes with dangling or small parts. It’s great to be ambitious but smart to start small and build up over time to the full unicorn dog costume with flashing lights.

Getting the Fit Right

When it comes to pet costumes, it is worth taking the time to measure your dog’s body and head to get the exact measurements. Every breed has such distinct proportions that S, M, L doesn’t cut it on size. This is especially important if your dog weighs over 60lbs. I found most of the negative reviews from people with large dogs related to XXL costumes actually being for smaller dogs. Ensure the costume doesn’t limit movement and if it’s difficult for them to see or hear it will likely increase anxiety.

Make it Fun

You will have greater success if you take some time for your pet to get used to their outfit and make it a fun experience. Before you have any plans to put it on, let them have a good sniff and get used to it. When putting it on take it slow, provide positive reinforcement, and follow these training tips from the AKC and Humane Society.

Make it Safe

Pets communicate through body language. A costume may inhibit some of those messages when they are around other animals. Help them out and pay attention to their body language. They can also have some anxiety about you or your kid’s Halloween costume, so give them time to adjust.
