#1 Overall Best Dog Spider Costume: California Costumes Dog Spider Costume

California Costumes makes this super-spooky spider costume for dogs, and it transforms a cute and cuddly pup into a ferocious, hairy spider.

The full-body design features a hood with four scary yellow eyes. Compared to other costumes that just make a dog look like a big spider is on its back, your entire dog will look like a spider with this costume. Each of the eight spider legs also has fuzzy orange fur for an even creepier look, which makes it especially adorable on small dogs with short legs. However, a few customers have reported concerns with the legs not having as much stuffing as they would have liked. In addition, while the headpiece is adorable and completes the outfit, not all dogs will enjoy wearing it.

This costume is available in four different size options: extra-small, small, medium, and large. The extra-small is suitable for dogs with a chest girth between 12 and 16 inches and a neck girth between 10 and 12 inches, and the large is best for dogs with a chest girth between 24 and 28 inches and a neck girth between 16 and 20 inches. You can reference the size chart if your dog’s measurements fall between these two sizes.

The Dr. NONO Dog Tiger Costume from Sweet Pet Garden is our top choice for a few different reasons. First, we love the orange color and realistic-looking tiger print. We also really like the hoodie design that gives the dog tiger ears without fully covering its face and making it uncomfortable.

Another thing we really like about this option is the soft velvet and polyester fabrics that were chosen for the costume. Not only does the costume feel like it will be comfortable for a dog to wear, but it also feels well-made to withstand the test of time.

This costume can be hand-washed or cleaned in the washing machine, which certainly makes things easier. It comes in five sizes (small, medium, large, extra-large, and XX-large), and is designed to fit dogs between 3.3 pounds and 16.5 pounds.

What to Look for When Choosing a Costume for a Medium-Sized Dog

Materials and Comfort

Most dogs do not wear clothing on a regular basis, so dressing up may not feel natural to them. It’s important to choose costumes that are high-quality and made from soft, breathable materials to keep your dog comfortable and free from injuries. If you choose a costume that is uncomfortable, not only can it harm your dog and cause pain or discomfort, but it will create a negative association with the holiday and with dressing up for your dog.

Also take into consideration which activities your dog will be participating in when they are wearing their costume. If it is for a quick photo shoot, you probably don’t need to worry about the costume’s flexibility and moveability. However, if you are taking your dog trick-or-treating or to a party, you’ll want to be sure they can move around while wearing their costume. If they are going to be outside, be sure they are dressed warmly for cold weather. If you live in a hot climate, make sure the costume is lightweight so that your dog doesn’t overheat.

Color and Design

Just because the costume looks cool in the product’s online photos, doesn’t mean that it is suitable for your dog or for the occasion. Some costumes are designed primarily for still photoshoots, while others are designed for more movement. With our recommendations for the best dog costumes, we’ve taken how well or not the costume is designed into account. This is important because many customers have ended up unhappy with previous purchases because their dogs couldn’t walk or run in the costume without experiencing issues. We want to make sure that your dog enjoys its evening out!

Size

Before you finalize an order for a dog costume, be sure to check the sizing chart provided by the manufacturer. This will ensure that your furry friend is comfortable and looks great on Halloween night. To get accurate measurements, use a tape measure to jot down your dog’s neck girth, body length, height, and weight.

In addition, be sure to check customer feedback if available. That way, you can avoid complaints about having to size up or down. If necessary, adjust your choice in size for your dog. And it’s always helpful to order your dog’s costume in advance, just in case you need to make any adjustments or exchanges.

Safety

If you’re going to invest in a costume for your dog, make sure it is one that won’t pose a choking hazard and won’t cause harm or pain to your dog. Inspect the costume before purchasing, and read customer reviews to get an idea of how well-made and durable it is. Also, consider practicality when choosing a costume by making sure there is some way to attach a leash or lead.

Best Costumes for Medium-Sized Dogs FAQs (Frequently Asked Questions) 

Are costumes safe for dogs?

Although dressing your dog in a Halloween costume does come with certain risks, as long as you’re closely monitoring them while they’re dressed up, they’ll be safe. Just be sure to never leave your dog alone while they are wearing their costume.

Dogs aren’t used to wearing any type of clothing at all, so a bulkier costume will feel strange and uncomfortable to them. This increases the chances of the outfit getting snagged on something like furniture or an outdoor item, which could potentially trap and injure the dog. Costumes that are too snug or too small can be hazardous as well.

You should also avoid costumes that have small parts. Smaller pieces could easily be chewed off by a dog and cause them to choke. Swallowing any piece of the costume also wouldn’t agree with a dog’s stomach, causing issues later on down the road.

In addition, make sure that your dog is comfortable, and that their costume is breathable so that they do not overheat.

It’s essential to remember that some dogs feel anxious when they have to wear a costume. Even though many dogs don’t appear to mind getting dressed up, there are plenty of others who do dislike it. If your dog falls into the latter category and becomes nervous around his or her costume, then it would be best not to make them wear one.

How do I know what size costume to buy for my dog?

It’s not uncommon for dogs to enjoy being dressed up. In fact, some pups appear to take pleasure in wearing clothing or costumes and may even get excited when their owner brings something out for them to try on.

However, not all dogs respond favorably to costumes. In fact, some may feel anxious or stressed if you try to put one on them. If they show signs of discomfort, don’t force it as that could make their anxiety worse and lead to other behavioral or health problems down the road.

How do I know what size costume to buy for my dog?

You will need to use the manufacturer’s sizing chart to find the right costume size for your dog. Even if you know what size costume your dog wore last year, take new measurements and check the sizing chart because each manufacturer has different sizing, just like in human clothing.

If possible, order your dog’s costume early in case you need to make any adjustments or exchanges.
