Are Dog Swimsuits Necessary?

Besides being stylish and fun, there are actually some functional benefits to dog swimsuits. Here are a few reasons bathing suits for dogs can add to your pup’s comfort and protection while swimming: 

  • A shield from the sun. Just like us humans, dogs can get sunburn, especially on their noses and bellies. A dog swimsuit with UPF protection can help prevent this. And don’t forget the doggy sunscreen!
  • Extra insulation. Swimsuits for dogs also provide a layer of insulation for canines who swim in chilly water.
  • Skin protection. If your dog has sensitive skin, a dog swimsuit can help shield them from irritants in the water, such as salt or chlorine.
  • Cleaner fur. Dog bathing suits can help to keep dirt and debris out of your pet’s fur if they like to swim in lakes or the ocean.

Dog Swimsuits and Trunks Buyer’s Guide

When looking for the right swimsuit for your pet, here are a few things to take into consideration. 

Safety features. Think about what you’re looking for in a dog bathing suit. Is it purely for fashion or are you looking for safety features such as reflective accents or protection from the sun? 

Color. For ocean or lake swimmers, you may want a bright color that you can easily spot from a long distance. 

Convenient dressing/undressing. Choose a dog swimsuit that’s easy to put on and take off. It also may be beneficial to look for suits that are adjustable or made with stretchy fabric.

Size. Be sure to take your pup’s measurements and read the production description of what sizes and/or breeds the dog swim trunks or bikini is recommended for.

Customer input. Don’t forget to check the reviews like we did to see what other pet parents liked or didn’t like. Many customers even post photos of their pets in dog bathing suits, which are helpful to see. 

Return policy. Lastly, review the online retailer’s warranty and return policy in case the dog swimsuit isn’t the right size or doesn’t work out.  

Tips for Dressing Dogs in Swimsuits and Trunks

If your pup is new to wearing pet attire, try starting with just a few minutes at a time in the suit while praising and rewarding them with treats. After a while, your furry friend will most likely get used to the dog swimsuit and even begin to enjoy wearing it. 

It’s important to make sure your pup is comfortable in the outfit and that it’s not at all restrictive. Your pup should be able to freely swim, walk, run, and lie down in their swimsuit. 

Not every dog is a fan of wearing clothing, and some will straight-up refuse it. My Rat Terrier won’t even move with just a shirt on! If your dog seems uncomfortable or stressed in a swimsuit, don’t force it. Canines won’t offend anyone by swimming in their birthday suits! And if your pup isn’t a fan of water activities, there are plenty of other ways to keep them cool and protected during the summer months, such as providing shade and plenty of fresh water.
