What to Consider When Buying a Dog Onesie

Size— You may think your dog is size small, but is he actually? The only way to know is to measure your dog with a tape and compare it to the seller’s chart. If you don’t have a fabric measuring tape, here’s a trick: Use a string or ribbon to measure the area and then measure the string against a metal tape measure or ruler. Since sizes vary, it’s the only way to prevent returns. This is even truer if your dog is like my and doesn’t have a traditional “proportional” body (aka his body is long but his legs are short).
Does your dog like onesies?— Even if your dog likes sweaters, he may not like onesies. Since jumpers also cover your dog’s legs, he may be annoyed or uncomfortable with them.
The design— If you want your dog to be able to wear it throughout the season and not just Christmas, you may want to consider a design such as a snowman instead of a Santa. If you want your pup to wear it year around, consider even a less symbolic design.
Alternative to Cones—Onesies are adorable and some pups love to wear them just because it keeps them warm. However, they’re also useful if your dog has surgery or a skin condition. For example, if your pup gets spayed, she will need a cone to stop her from biting her incision open. Instead, a onesie can help protect the area or be used in addition to a cone. Also, some dogs bite at their skin or lick their hot spots, making them worse. Wearing a onesie prevents them from getting at the area and reduces healing time.

#2 Donut Dog Onesie

Omg! These are one of the most arable onesies I’ve ever seen! Will your dog prefer a sprinkle donut, chocolate dip or a cinnamon flavored one?

#3 Red Plaid Dog Onesie

This lightweight but thick onesie will keep your doggo warm and can be worn during the holidays or all year around. The most beautiful part to this is you can buy any red plaid outfit and it will match! Here’s some suggestions:

Pawsative Ruffview: “I love these! They are high quality material, thick and soft. My dog is long but thin so he’s kind of always at an “in between” size where nothing fits him perfect but this has stretch to it and it fits great! He’s a 14 lb shih tzu mix and Medium was perfect.”

Grey
Orange
Pink

#5 Comfy Knit Grey Dog Onesie

These pajamas are soft and lightweight while still being warm enough for sleepy time or everyday wear.

Pawsative Ruffview: “So far so good. Seems to be made well and covers his hot spots until we can get him to the vet to see why he’s pulling his hair out so bad. I would recommend the product.

#7 Unicorn Pitbull Onesie or for Other Breeds

If you have a hard time getting onesies to fit your pitbull, this one is perfect for you, but it will also fit other medium to large breeds.

Pawsative Ruffview: “After putting this on my dog, I had to physically cover my mouth to stop me from screaming because I’ve never seen something so adorable in my life. My dog has a wide and flat chest and normal dog clothes do not fit him perfectly (he is 55 pounds). This is the first doggie pajama that gives him enough space around his chest and neck. I don’t have to roll up the back sleeves either like I usually do with other dog pajamas. I’ll be buying more for sure. Thanks Tooth and Honey!”

#10 Multi-Color Paw Print Onesie

This adorable onesie has a gradient-style color that fades from pink to green, featuring paw prints throughout. Also comes in a dark blue ocean theme!

Pawsative Ruffview: “I ended up ordering a small and medium because my girls are at an awkward size right now where they sometimes need a small and sometimes need a medium. They are also miniature dachshunds so they have unique measurements as it is. I thought the small fit both of them the best. First picture (black and tan doxie) is 8.5 lbs with a chest girth of 14.5 inches, a neck of 9 inches, and a length of 13.5 inches. Second picture (black brindle doxie) is 10 lbs with a chest girth of 15.5 inches, neck of 9 inches, and a length of 13.5 inches. It seems to fit both of them well, length will never be perfect for dachshunds and the legs may be a tad too big on them with how short their legs are but overall, I am happy with this product.”

#11 Dog Onesie to Reduce Shedding

Unlike any of these other onesies, this one claims to reduce the amount your dog sheds and to reduce his anxiety. Although it doesn’t have a Christmas design, the bright red option is sure festive, so it can be worn Christmas and all year round! However, it also comes in:

Blue
Pink
Black

Pawsative Ruffview: “My rule for our new car was NO DOG! Phoebe has short wiry, tawny-colored hair that embeds itself in fabric so well that I have to use tweezers to get it all out…and she sheds A LOT! I swore she would not ride in our new car with it’s pristine black interior. When it was obvious there was no choice I thought of making her pjs to keep her shedding to a minimum. Luckily I came across the Shed Defender Onesie. Everyone thought I was nuts, including Phoebe, but I love them! It was quite comical when we first put them on her until she realized that the fabric was not restricting at all. Soon she was running and jumping like she always does. Now she equates the red pjs with a ride in the car and stands patiently while we slip them on. And I’m a happy camper because my new car isn’t full of dog hair. I am so pleased with this product that I had to write a review, which I rarely do. Thank you for saving the day!!”

#13 Duck Dog Onesie

These onesies will make your pup look like an actual baby! Would be adorable for when your dog dries from a bath too! “Rub a dub dub, doggo out of the tub!”

Pawsative Ruffview: “I purchased these for my pup for Christmas Eve. I have a 20 pound West Highland White Terrier – I ordered a large. They fit perfectly! He is not the type of pup that enjoys wearing clothes, but at no time did he tug at them and try to get them off. This is my first purchase from FitWarm but it’s definitely not my last.”

#15 Fuzzy Pink Bow Onesie

Here’s another warm fuzzy onesie for pups who can’t get enough warmth. It’s made from fleece and would look adorable for photos or just watching your dog at sleepy time.

Pawsative Ruffview: “My Pomeranian has hair loss issues so she gets cold in the winter time. I decided to try these and I am so glad I did. They are very nicely made of good fabric. The measurement guide was spot on so please follow that. My dog is only 9lbs but measured closer to a medium. I wanted her to have a little room so I went ahead and ordered the medium. It fit perfect. They are easy to put on and she seems very comfortable in them. She is not a fan of the bow so I will probably take it off but as you can see from the pictures its really cute with the bow.”

#16 Beautiful Flamingo Dog Onesie

In my opinion, this is one of the most beautiful onesies on this list! With a pastel fading color design and flamingos spread throughout, it’s perfect for any feminine doggo!

Pawsative Ruffview: “These are adorable. Our new rescue’s fur was overgrown and matted when we adopted her. Our groomer had to shave her fur almost to her skin to remove the knots. She needs jammies like these to keep her warm. I like having all four of her legs covered. Our new little girl is a Terripoo, & weighs 12 pounds with a long back. The large fits her perfectly with some room for her fur when it grows back. The jammies are so soft & easy to put on her. She gives these jammies 5 barks!”

Pawsative Ruffview: “OMG! This outfit is beyond my expectations. I purchased the XS for a 3.5 lbs. Yorkie (8in long back) and a medium for a 7.5 lbs. Yorkie (12 in long back). These pjs are soft, stretchy, beautifully finished. They hug my critters nicely, without constraining their moves. They did everything yesterday when I first got these: lounging, sleeping, chasing the rabbits, walking on the computer keyboard, watching TV, chewing on the Greenies, and doing their stuff in the backyard…
They fit perfectly and yes, my babies fell asleep immediately in these fluffy soft, warm, PERFECT pjs!!!. I’m ecstatic! Just look at these pictures 🙂 The little one I’m holding on my forearm, is falling asleep as you are reading this, ha ha!”

Another beautiful onesie, this design features a super soft velvet fabric with unicorns jumping. Comes in sizes from XSmall to XXL to fit almost every dog.

Pawsative Ruffview: “Finally jammies that fit my little furbaby!! I measured her before ordering & followed the size guide and these fit perfectly! They are very well made & I love that the cover her entire back. She does pull her little legs out of them, but that is no fault of the jammies. I had stopped buying her clothes because they never fit, but these were so cute I thought I’d give them a try. I’m so glad I did! I am very impressed with this brand & already ordered some more. Highly recommend.”
