In August of 2020, we launched the Fi Makers Program - a collaboration between Fi and various other collar companies to provide our Fi dogs with unlimited collar options for their Fi module. You can check out all of our Makers here.

We've partnered with these select companies not only for their high quality and durable dog gear, but also because of how much they give back to their community and care for their 2 and 4 legged customers. We'd like to introduce you to the people and pups behind some of the brands:

Trek dog

Creators Lilian and Nicholas and Co-Creator Zachary, founded Trek Dog alongside their dogs, Kodiak, Delta, Luna, Griffin, and Buckley. This group of friends came up with the idea after realizing their dog's gear usually needed more scrubbing than the dogs did after their hikes!

Lilian, Kodiak, and Delta of Trek Dog!

Along came the idea for Trek Dog - adventure gear that's made for everyone. Whether you and your dog prefer casual strolls or intense hiking, Trek Dog products are made to stand up to any adventure.

The Trek Dog team handcrafts each item in their home state of Rhode Island. One of Trek Dog's great accomplishments is also launching the Trash Trek Initiative - they believe that taking care of the environment is a community effort, so they challenge everyone to pick up trash whenever they see it and to remember to carry out what you carry in! The packaging that you receive your items in is also eco-friendly, biodegradable, and recyclable.

Mutt Pack

Michele and her rescue pup, Piper, started Mutt Pack in 2017. As a puppy, Piper was a bit of a troublemaker and her favorite past time was chewing up her leashes and playing tug-of-war with them on walks. Puppy parents, you can probably relate!

Piper, Co-Founder of Mutt Pack!

Constantly throwing out and buying new leashes was not only expensive, but also wasteful, so Michele decided to solve the problem by making her own leashes. Shortly after, she opened up an online shop and Mutt Pack was born!

All Mutt Pack gear is hand made with Biothane and you can be sure it will stand up to your rambunctious puppy or adventure loving dog! Another great thing about Mutt Pack? They give back to their community by donating to rescue groups like Great Dog Rescue New England, and Operation Delta Dog each month.

FKN Pretty

Meet Jenna and Joe and their dogs, Dixie and Daisy - a couple who lives to make people laugh and smile! That, along with their love for design, inspired them to create FKN Pretty.

Jenna and Joe and their crew - twin pups, Daisy and Dixie, twin cats Saturday and Sunday, a chicken named Sugar, and lazy dog Chowder.

If you believe that life doesn't always have to be so serious and being different is more than just okay, then FKN Pretty is the brand for you and your pup. Their unique and elegantly inappropriate designs are almost guaranteed to make you laugh and turn heads at the dog park.

So why FKN Pretty? In the words of Jenna and Joe - "Because life is short and laughter is truly a universal language."

Sexy Beast Dog Collars

Jen, owner of Sexy Beast Dog Collars, says that this company is truly a labor of love. She started out making dog collars just as a hobby and to use her creativity as a stress-relieving escape from daily life.

When two of her Rhodesian Ridgebacks, Henry James and Tank, both passed away due to cancer just 8 months apart, she took on an endeavor to create dog collars for the National Canine Cancer Foundation, called the "Let's Collar Cancer" Campaign and her business took off from there.

Sexy Beast Dog Collars became a real business in 2011 and they are now a crew of 3 humans and 3 pups - Ronan, Fergus, and Cormac - who's job description includes modeling, product testing, lunch supervision, and lounging about in various areas of the shop. It's clear to see that this team loves what they do and they look forward to many more years of creating beautiful, quality dog gear for your pups!
