How to Choose the Best Dog Shark Costume

Before you purchase a new shark costume for your dog, there are a few different features you’ll want to consider. Evaluating these features can help ensure that both you and your pup will love the costume you select.

Size

Choosing a costume that is the proper size for your dog is important. Manufacturers should post a sizing chart to help you confirm whether a costume should fit your pup. Depending on the design of the specific shark costume you’re looking at, you may need to measure your dog’s neck, chest, or overall lengths. Many sizing charts also include a weight range to provide you with additional information to ensure a proper fit. Also do a little research on customer ratings at sites where the costume was purchased to get an idea of whether the costume runs bigger or smaller than the chart indicates.

Bulkiness

In addition to paying attention to the size and measurements of each shark costume, also consider how bulky each option is. If a costume is overly bulky, it may not be comfortable for your dog to wear for very long, since it may make it more difficult for them to walk or lie down. Additionally, if you’re planning on bringing your dog anywhere in the car, a bulkier costume may make it more challenging to do so.

Materials

Choose a shark costume made from comfortable materials that aren’t likely to irritate your dog’s skin. You should also look for costumes made from lightweight fabrics. Dogs already have a fur coat, so adding too much weight on top of their coat may cause them to overheat, especially if you’re taking them out on a warm and sunny day in their costume.

Safety

As we mentioned above, various components of a costume could become a choking hazard. Closely evaluate each costume for any smaller parts that may be easy for a dog to remove and try to chew on. This is true for all dogs, but even more important if your pup is known for chewing on items.

Our Criteria and Experience–How We Chose the Best

We want nothing more than for your dog to enjoy his experience as the king of the deep! When we chose our top recommendations for shark costumes, we took into account the quality of the materials used, the durability of the costume for short-term wear, how well it fits (and if the sizing chart seemed to line up with how the product actually fit), and reviews from customers. Here are some notes for you to consider:

  • Our overall best pick for a dog shark costume is a great choice for a full-bodied option. The combination of fleece and velvet is soft and comfortable for your dog. It can also be warm, so keep your climate in mind when you take your dog out for any extended time in this costume. We liked the plastic snap features to aid in getting your dog in and out of the costume fairly easy. Do note that customers found that the costume seemed to run a bit small based on how it fit on their dogs.
  • The #2 shark fin is actually a piece made not only for pets but also for humans! The soft velvety chest strap is stretchy to fit your dog comfortably. We liked the fact the fin is an easy sell for the more fussy dog, but some customers said it ran small, so take that in mind when seeking the correct size.
  • We think a swimming life vest like our #3 pick is a great option for the canine water lover! The shark fin on this dog jacket adds style to safety, and the jacket is constructed from durable and high-quality materials. The smaller sizes of the life jacket may be a bit bulky for small breeds, though, so be aware.
  • We had to include a hat option, and we found our #4 pick to be a hilarious show-stopper! While we’re sad it doesn’t run large enough to fit all sizes of dogs, it’s a great choice for your small or medium-sized dog.

Check Out the Best Dog Shark Costumes: Reviewed for 2022 FAQs (Frequently Asked Questions) 

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

Finding the right size dog costume should be pretty simple. Most manufacturers include a sizing chart to help you get the right fit. Depending on the costume you select, you may need to take measurements of your dog’s neck, chest, and/or overall length. Many sizing charts also include a recommended weight for each costume size.

Is a shark a good costume for a dog?

Sure! You can find shark costumes that will make your dog look cute, as well as ones that will make them look more ferocious. The choice is really yours depending on what you’re looking for.

Where can you buy a dog shark costume?

While you may be able to find some shark dog costumes in store, your selection will likely be more limited, and you may not be able to find the correct size for your dog. Buying online from a reputable company, such as Amazon, will offer you a much larger selection of shark costumes available in a wide range of sizes.

Should I get my dog a full shark costume or just a shark fin?

The answer to this question depends on both your preferences as well as your dog’s preferences. Think about whether your dog will tolerate wearing a whole-body costume, or whether they may be more comfortable in just a shark fin that straps around their body. You can also think about the overall look you’re after and whether you’re trying to coordinate your dog’s costume with what you’ll be wearing or what others in the family will wear.

What should I do if my dog won’t wear his shark costume?

While some dogs enjoy getting dressed up, others don’t like wearing a costume. If your dog doesn’t want to wear a costume, you shouldn’t force it. It may cause unnecessary anxiety, which could lead to other health issues down the line.

If your dog seems nervous, you can try leaving the costume on the ground for them to sniff and see if that helps improve their comfort level. But, if they still seem hesitant after that, forcing them into the costume just to get some cute pictures or comments for others isn’t worth the risk to your dog’s health and happiness.
