Chloe, thank you so much for the beautiful cake that you created for my baby English Bulldog, Dolce. You made her 1st birthday wonderful.

Cosmo’s Dog Bakery has the best dog treats and with them baking all the cakes and cookies on the premises it smells amazing.

I will continue to get my pup cakes and treats at Cosmo’s. They truly show that pets matter.

What a hidden gem! I was at a Frenchie Meetup at the Works when my Frenchies pads started bleeding from the cement. I didn’t want to ruin his playtime so I took a chance and popped into Cosmo’s to see if they had any boots. Christy was beyond amazing. She helped fit Rafi with boots and was so patient with his crazy puppy energy. I can’t thank you enough for being so amazing!

Every year they've done a great job with my pup's cakes. Great place to pick up treats, food, and Cosmo's own biscuits and pupcakes. Good rewards program as well.

Been coming here for years. I have too many good things to say! Extremely friendly staff, knowledgeable staff, huge selection of pet goods, even specialty pet goods. We buy the cakes and cupcakes every year to celebrate our pets birthdays! I ordered my first custom cake this year and my dog loved it! Thank you Cosmos for all the hard work. We LOVE you guys!

This has been the go-to place for our dog's treats, so obviously my husband and I wanted to order a custom cake to celebrate her 1st birthday! Despite my vague instructions, the talented bakers here utilized their creativity to make the perfect cake for Wednesday's 1st birthday! I'm incredibly happy with the results.

Overall, Cosmo's is filled with wonderful people who truly care about your animal family members as much as you do. I'm grateful that a local business such as this exists in our community.

We absolutely LOVE this bakery/store for many reasons! Here are just a few main ones:

1) Soul Dog Rescue hosted an adoption event with the bakery. The same dog we looked at a week ago in the shelter happened to be at their event. We got her that day in August!

2) They made our girl's beautiful customized birthday cake. She and her friends loved every bit of it!

3) Employees are so friendly and kind. They greet you with smiles and are glad to help.

4) Good prices for the high quality products & delicious dog treats they sell.

We’ve been getting our dog’s birthday cakes here for a few years and we have always been so impressed with the design and quality of the cake. Our dogs are big fans too! I felt the need to write a review because of how amazing our most recent cake purchase turned out. Great customer service as well!

13:56 14 Aug 24

The cake was well crafted, thoughtfully protected, reasonably priced and my dog loved it!!

I called this place to order a cake after being referred by a friend. I left nearly all direction up to the baker(s), so I wasn't sure what I'd be getting when I picked it up.

From the time I placed the order, to the time I picked it up was only 2 days. Customer service was great.

When I picked up the cake, I was thoroughly impressed. They went above and beyond, exceeding all expectations. The cake was well secured in a box, ensuring safe delivery on my way home. The cake was placed on a cardboard platter which was taped to the bottom to ensure it wouldn't move around in the box.

We recently purchased a cake for our pup's birthday and I am so incredibly impressed with the creativity and customer service. The dogs absolutely loved it! Thanks, we'll definitely be back!

Original review:
We’ve been coming here for the past 6+ years for our dogs supplies and custom birthday cakes. Between all of our dogs we’ve had over 20 cakes made over the years and there is no stopping in sight! Our dogs love the cakes, we love celebrating them with something special and delicious and it supports a local business. We cannot say enough amazing things about Cosmos!

Every experience ordering and shopping at Cosmo's exceeds five stars! I have ordered several cakes through them and we are always SO thrilled. The shopping experience has something for everyone, I particularly enjoy their supply of sustainable and clean products from chews, treats and bones. Their freezer selection is my favorite in all of the Denver area! Every employee is such a delight, especially Frenchy, who I could chat with forever. Very appreciative of this gem, I recommend it to all our friends and family.

I absolutely love Cosmo's Dog Bakery! I have ordered two cakes from them in the past for my dogs birthdays and they both turned out incredible, I was in awe when I picked them up. I just placed my next order with them for my dogs upcoming 7th birthday and am so excited to see it in a few weeks :)

Exceeded all expectations! We were absolutely blown away by how perfect our cake was. We uploaded pics to inspire the design, and they nailed it!! Pups loved it too. It smelled so good, we almost tried it. 😂

The ONLY place to go for your doggie cake needs! My big boys cake was an absolute hit. Thank you Cosmo’s for helping make his birthday so special!

Love love LOVE this shop. I love the products for my dog, I love the people that work there and I love the quality! I am a technician so I tell everyone I meet about Cosmos and always have a bag of Eddy Goodboy Stars or Stink Bug Project cookies in my work truck for all the dogs I meet every day! Top tier dog shop.

If I could give more stars I would. Cosmo’s is amazing! Their cakes, products, and staff make this place special! When we take our pups into the store they get spoiled with treats and love. We feel lucky to have them in our community!

This place is awesome! It’s small but mighty. The best part is all their dog bakery treats. I specifically came in to look for a birthday cake and pup treats for my dog’s birthday party. They did not disappoint! I was looking for pink specifically and found so many options. But was able to get a cake and several dog cupcakes. They also have dog ice cream options as well.

The staff was super friendly and helpful. The store was so clean and organized. I will definitely be coming here for my dog treats from now on.

The staff are definitely animal lovers, they greeted my boy with a snack (asked me first👍) he had in house made pumpkin yogurt and a pumpkin cookie from the bakery. We will be returning soon, great business!

I've been meaning to leave this review for months and months. Cosmos is hands-down the best pet store that I've ever been to! Their selection of different treats and chews does not compare to any other pet store that I've been to. My dog is always so excited to be there, and all of the employees know my dog and even ME by name! They are so patient and really work to build a relationship with the customers and their pets. While I've been in the store, I've noticed that they are like this with all of their repeat customers. I really can't ask for more out of a business, people and pets are treated like family here! Thank you Cosmos, I am so lucky to have a store like this in my area!!!

I recently visited the Colorado History Museum, and bought a mix of cookies called the History Hound Blend! My dog LOVED these cookies! I feel great about giving her these treats because I know there aren't extra filters and toxic ingredients! Definitely buying more know that I have the website and location!

Ordered a custom themed birthday cake for a doggy friend who doesn't like toys (so I was stumped what to get for his bday!) And it turned out better than I could've hoped! The "small" cake was plenty reasonable for 6 dogs who devoured the treat, and all the humans were obsessed with the cake too! Super easy to order online, was ready for pick up when I wanted, and the staff was super friendly. They have everything you could need for your furry friend in store. Will def be visiting again!

Awesome spot for dogs! These custom dog cakes are legit. Highly recommend treating your pup to one of these. The selection here really is incredible.

I ordered a birthday cake for my puppy's first birthday party, and it was such a great experience! The online ordering process was super easy, the pick-up was smooth, and the cake itself turned out SO cute! The store is also adorable and chock full of all kinds of cool stuff your pets will love (which can get a little dangerous when you go to pick up your cake!) :) Highly recommend this great shop!

Cosmo’s is amazing!!! I ordered a custom cake for my baby girl’s first birthday. They did such a great job with her frozen princess cake!!! The ladies were also super nice when I showed up earlier than expected to pick it up! The store is so cute and we will definitely be back for future treats!!

Christy has done a wonderful job at remodeling her store. You can actually watch the bakers making all the dog treats. Has an absolutely fabulous range of products for you pet. It IS my go to spot for anything dog related. Great selection of toys and treats. Can't wait for the Official ReOpen House on April 22 and 23. AND she has a GREAT staff to help you.

This is the cutest little pet bakery and store. Everyone here is really friendly and helpful when you are in search for certain products. It's easy to spend lots of money on our furry family members. There are gifts for all holidays and occasions. I love buying my shih tzu cute cookies from here.

Friendly service, local, dog biscuits that will make your pups eyes light up and mouth water! We got our first batch with a local coupon and after our dogs loved them so much what could we do but order some more, and some for my brother's dog too... So give Cosmos a chance and you might just be hooked.

The people at Cosmo's are always friendly and willing to help you find what you need for your furry friend. They have a great dog food selection at great prices and a bunch of different treats to choose from - they even make their own treats!

Cosmos was able to accommodate a last minute request for a cake to send our girl over rainbow bridge. She loved it, and it was so much more beautiful than I ever could have anticipated. I cannot recommend this place enough and appreciate their compassion and ableness to create something day of.

I wish I had five hands so I could give Cosmo's five thumbs up. The employees are so friendly, engaging and happy to be here it makes every trip to buy dog food a treat. Dogs are welcome and Frenchie remembers every single dog's name as soon as they walk in the door. When it comes to holidays and birthdays this is the only place to go, amazing, personalized cakes baked with dietary restrictions in mind. All ingredients are human grade and you'll certainly find me sneaking a few fingers of frosting (honey and cream cheese, yes please). They even made a special little cupcake for my cat on her birthday and included a bit of catnip to get her interested because we all know how cats can be. Brighten up your day and stop by Cosmo's even if you don't need anything.

💛 🖤 Today we celebrated our golden boys 10th birthday! Happiest of birthdays to our pretty boy, Hawkeye! He is LITERALLY the most well behaved, kindest, snuggliest….. and perfect dog…. In my opinion! 🤣 🐾 Thank you Cosmo's Dog Bakery and Natural Pet Supplies for always going above and beyond on my babies cakes! The talent at your bakery is unmatchable! 💗🙌🏻

The Cosmo's Bakery Team is truly one of a kind! I recently requested a cake to be made in celebration of my best friend's dog, Buddy. They went above and beyond for our special man- and we are overwhelmed with gratefulness. Thank you for making this good bye a little less sad. We will never forget your kindness.

May the universe bless you all!

My best friend ordered a cake for my dogs party, as we just found out he has cancer. We are gathering our family to make buddy feel as loved as he has made us feel throughout his 13years. I didnt expect the type of wonderful service we got, or the sweetest email from this company reaching out to give condolences. This has been a very tough ride, but this place made it just a little easier to get through. Thank you. I cant thank you enough. My heart Is full.

THE best pet store in the area for supplies, customer service, and a wealth of information! Bring your dog on in for a bounty of affection while you shop for their next bag of food, toy, treat, leash, and more! The shop assistants know everything (seriously, amazing) and will happily guide you to new products. It's always a joy going to Cosmo's! (Small alert: the parking lot in front of Cosmo's is VERY tight. There is more parking down the hill to the left!)
