What serious breeders say about BreederBuddy

Breeder Buddy has been the perfect addition to my dog breeding business! It is so well put together and organized and keeps all of my information in one place.

I was having a very hard time remembering and managing all of the information, tasks, appointments, etc without some kind of software, and I actually tried a few different ones, with this one definitely coming out on the top.

The platform itself is easy to navigate, well designed, with a modern and clean feel while still offering a ton of options for keeping everything you need all in one place. I also love the ability to sync my dogs and application process up to a website, and everything integrates so nicely.

I have built websites in the past, but it had been a long time, and Kenny took the time to help me get started and point me in the right direction. Truly Kenny’s availability, capabilities, and willingness to help is the best “feature” in his program! He is so nice, and always willing to lend a hand. It is very hard to find a tech type program anymore that has a real person on the other side helping you through it.

I 100% recommend Breeder Buddy to any dog breeder out there looking to organize and streamline their business!

I cannot rave ENOUGH about this breeding program software! The genius behind it, Kenny, is absolutely wonderful to work with, he is very responsive and is always willing to troubleshoot and communicate.

I breed dachshunds and since having switched to breeder buddy, it has been a game changer! He listens to breeders and takes our ideas and implements them to make the website/software even better! I love the design and the health reports for my dogs, keeping track of all their information is far less stressful and chaotic now.

Kenny even helped build me my very own breeding website! 1000/1000 would recommend this platform to any and ALL breeders! Thank you for making my life easier and for being there every step of the way!

We used Kenny to build a custom website and although it was a bit out of the norm for him as we are a Rescue as opposed to Breeders he did an amazing job!

In addition to the care he took to build the site he also set aside time to meet with me to make any changes or adjustments as well as to teach me the ropes so I can make adjustments and handle things in the future. (Except the server and super technical security stuff) he will continue to handle that and endure the hosting is good.

Breeder Buddy has been an absolute game changer for our breeding program! The software has allowed us to stay more organized with our program dogs but also with our communication and payments with our customers as well. Breeder Buddy has created more time for us to focus on what matters the most, our dogs and our customers.

Behind every good software is an exceptional support team and that does not lack with Breeder Buddy either, the support team is just short of amazing.

Breeder Buddy changed our lives and our breeding program for the better, I would recommend it to anyone that is running a serious breeding program.

Breeder Buddy has been a fantastic addition to my breeding program. It’s clean, reliable, and thoughtfully designed for how breeders actually work. The communication features keep everything organized in one place, the health tracking is intuitive, and the record-keeping tools make it easy to stay on top of each litter’s details.

It feels like it was built by people who truly understand the rhythm and demands of a responsible breeding operation.

I’m grateful to have a tool that supports professionalism, clarity, and great customer service for my puppy families. Highly recommended.

“This app has been a total game changer for my dog breeding business. It has streamlined so many of my daily tasks, saving me time, money, and stress—and completely eliminating the need to hire office support.
One of my favorite parts is being able to sync everything with my calendar and access it right from my phone. Whether I’m at home or on the go, I have everything I need to answer buyer and vet questions, view important documents, and receive reminders to keep everything on track.

Kenny was incredible to work with. His deep knowledge of software development and website layouts made him the perfect fit to create both the Breeder Buddy app and the Arrowhead Labradoodles website.

Kimberly Williams Troup, Grace N Faith Doodles
El Paso County, CO

I LOVE Breeder Buddy! My regular job is running data and CRM’s, so I know a good database when I see one. Breeder Buddy is intuitive, easy, and very user-friendly! (if only I could get QBO to understand that concept!) From the very first interaction with Breeder Buddy, they have been open to suggestions and ideas for improvement, and very responsive if I’ve needed help with anything.

Just being able to track my puppies’ weights and litter has been wonderful. It works great on mobile and on a desktop. It is easy to add heat cycles to the calendar, along with vet appointments.

It is a FULL SERVICE product that is worth its weight in gold. It is a small investment with a HUGE return.

As a small part-time breeder, it helps me stay organized and is my favorite employee with the best ROI. If you are considering Breeder Buddy just open up the free trial already! You’ll be so glad you did!

✨ FAQs

Frequently asked questions about dog genetics & pedigree software

Can BreederBuddy predict puppy coat colors?

Yes. The Genetics Forecast feature calculates probable coat color and trait outcomes for any planned pairing. It shows probability ranges for each possible outcome, including when genetic testing is incomplete — so you know exactly what you might get and with what likelihood.

What is COI in dog breeding, and how does BreederBuddy calculate it?

COI stands for Coefficient of Inbreeding — a measure of how genetically related a dog’s parents are. A higher COI increases the risk of inherited health issues. BreederBuddy calculates COI automatically from your pedigree data and lets you preview the COI for any hypothetical pairing before you breed.

What genetic loci does BreederBuddy track?

BreederBuddy tracks 13 loci: E, K, A, B, D, CO, C, I, S, M, L, F, and CU. This covers coat color, texture, pattern, and size traits for the vast majority of breeds, including complex scenarios like M locus merle and expanded E locus.

What if I don’t have complete genetic testing data for a dog?

BreederBuddy handles incomplete data gracefully. It distinguishes between lab-tested results, inferred genetics (based on phenotype or known parentage), and unknown data. Forecasts display probability ranges instead of false certainty, so you always know how confident the prediction is.

Can I share pedigrees with buyers?

Yes. Every pedigree can be shared via a public link or exported as a printable PDF. You can also include a buyer-friendly genetic summary that explains the dog’s traits in plain language.

Does BreederBuddy support genetics tracking for cat breeders?

Yes. BreederBuddy supports cat breeding programs as well as dog breeding. Genetics and pedigree tools are available for both. You can switch your program type in Settings > Preferences.

Will additional support for more complex genetics tracking be added in the future?

Yes! We’re constantly making improvements. If you see something missing, just let us know.
