This Boy is Ready for His Forever Home!
Texas is a toy and almost 3 years old. He was born March 20, 2023. He is a BEAUTIFUL Red Merle and has had several litters for us. He is a sweet boy and wants to be your favorite! He and our other stud DO NOT get along and we have made the hard decision to neuter and re-home this boy. He is very nervous as a stud and we feel his life would be so much better NOT being a stud. After our dogs have worked so hard for us, we want to see that they have a fulfilled life, not being a breeder, and able to go on hikes, camping, etc., etc.. As breeders, we do not take our dogs anywhere, as we do not want to bring any disease into our 'kennel' (home), where we have so many litters. Therefore, he has not had many adventures.
He has been neutered, and he is up to date on all of his shots. A re-homing fee of $500 would be asked for. He is somewhat house trained, but being a stud we sometimes keep a diaper on him, in the house, since we have a lot of females. I am sure that no that he is neutered and gets used to his new home, that he will lose the possibility of marking in the house. Possibly, even before he goes to his new home. We have not had one accident since he was neutered.
He would thrive as a single pup, in your lap...., or with another small dog, as he is used to other toys.
If you are interested, please give me a call at 970-215-9488, or a text. We will schedule a time for you to come and visit with him.

welcome to warren's colorado toy and mini aussies
Marshel & Ann Welcome YOU!!
Explore the wonderful world of Toy and Mini Aussies and find your perfect companion today!
Welcome to OUR Wonderful World!!
We are Butch and Ann Warren.
A little bit about ourselves, we have lived in Berthoud since 2012. However, before that, we lived in Loveland from 1969 to 2012. This is our home forever! We visit new places that are beautiful, but we are always very happy to get back home!
We have had mini Aussies since 2014. Rylee was our first one that we got in 2014 and is now 12 years old! She is such a sweetheart, and it's ALL her fault! We fell totally in love with this breed, and in 2018 got Sherman, our faithful stud!. He gives us such gorgeous puppies, not to mention the sweet temperament that is always passed on. Before the Aussies we raised Great Pyrenees. Also beautiful dogs, but definitely not Aussies!
This is the best 'job' I have ever had, and it has been such a joy raising these precious pups. We get loves and cuddles all day long from our adult dogs, and the of course, there are the puppies! We handle and love on constantly, so they will be well adjusted and used to handing. I never get anything else done, and that's OK! It's definitely worth it!
If you are looking for a Toy or Mini Aussie, we invite you to visit. After the pups are 5 weeks old we have Puppy Play Days. This is where folks can come and see them, play with them, and see their playfulness.
We need to schedule a visit for that. Also, if you want to see the adult dogs that we breed, before a decision is made to get a pup (which we highly recommend), we can schedule that too. See our 'Purchase Info', for more details regarding our process.
Our website is kept up-to-date with new litter information, pictures and reviews from very happy clients.
The information, within the website, will be sure to put a smile on your face, whether you are looking for your new best friend or just want to see beautiful pups and adult dogs.
PLEASE, if you have called or emailed us, and have not heard back, try again. We get a lot of scammers and if you are not already a client of ours, your number is not recognized. Also, sometimes I do not receive messages. Text is an easy way to get in touch, so leave me a text, 970-215-9488. Texts come through, when emails, sometimes, do not.

Ann and Butch are lovely people that care deeply for their little friends. I definitely recommend them."

Keith & Marlene Stone adopted 'Sherman, Jr.' on 5/10/25
Keith and Marlene Stone adopted this little sweetheart. He is a mini-me of his daddy, Sherman. He is also his name-sake, Sherman Jr. He has one of the sweetest demeanors of all the pups we have had. The Stones are at home in Loveland, with Sherman Jr.!

"Warren's Colorado Mini Aussies is a top quality breeder of Aussies of all sizes! We had such a positive experience and Ann was extremely patient and knowledgeable, answering all our questions. Our new little "Sherman" - a mini, at 8 weeks is incredibly smart, and already knows 4 commands, is easy to house train, loves to be with us and shaping up to be the best dog we have owned. We were impressed by how much Ann knows and loves the unique personality traits of all her guys, gals and their pups! You can tell they are loved from the moment they are born and open their eyes! A great start for a great pup!"

Standards & Screening
We’re committed to the health and well-being of dogs — and to your peace of mind.
At Good Dog, we know that a dog is much more than a dog — they’re a member of the family and a best friend for life. When the source of your new best friend has such a big impact on their health, behavior, and well-being, finding the right one should not be left to chance.
That’s why we’re making it easy to connect with responsible, good breeders who have your and your new dog’s best interests at heart, so your pup has the best chance at a healthy and happy life.
What are our Community Standards?
Good Dog is on a mission to connect good with good to weed out the bad. In that pursuit, we have sought out and worked with some of the top academics and practitioners in the field to develop community standards, which are grounded in evidence-based research and backed by science. While there is no “one size fits all” for what makes a breeding program responsible, we are able to use our community standards to evaluate programs consistently. Every member of our community must pass our screening process and meet or exceed our community standards before joining Good Dog.
How do we evaluate breeding programs?
Our screening department comprehensively considers many aspects of a breeding program, focusing on five key areas:
- Breeding practices
- Physical health of the breeding dogs and puppies
- Mental health of the breeding dogs and puppies
- Environment
- Buyer education and policies
Each key area is assessed individually and an assessment is also made on the program as a whole.
Our screening process entails an online questionnaire, phone interview, and vetting by our screening team. Our screening committee then reviews the application for compliance with our community standards and makes an assessment.

What do we look for when screening breeders?
Breeding Practices
Responsible breeders make conscientious decisions when deciding to produce a litter. Responsible breeding requires a lot of planning, skill and experience. It’s not nearly as simple as pairing two physically healthy dogs together and hoping for the best. It’s critical that these decisions take into consideration the heritable health conditions that affect their breed, each individual dog’s health testing, and considering the parents’ temperaments, overall health, pedigrees, and conformation in order to make the best matches.
Responsible breeders collect experiences over decades and develop an intuition for bringing puppies into the world that are both physically and behaviorally healthy. New breeders are often mentored by a veteran breeder so they can benefit from their experience. We strive to work with breeders who are both well-intentioned and have this crucial depth of knowledge and expertise, as well as up and coming breeders with a desire to learn more.
When making decisions about their breeding programs, responsible breeders always prioritize the physical and emotional health, and well-being of their breeding dogs above all else, including financial gain.
Physical health of the dogs
Responsible breeders always put the physical health of their dogs first.
Mental health of the dogs
Responsible breeders ensure that their breeding dogs’ emotional, and cognitive needs are met by ensuring they receive appropriate stimulation, activity and social interaction. They are also devoted to producing behaviorally sound puppies.
Environment
Responsible breeders ensure their dogs have a clean, comfortable, safe, stimulating, and enriching environment so their breeding dogs and puppies will thrive.
Buyer Education and Policies
Responsible breeders spend a great deal of time with potential puppy buyers to help guide them into making an informed, responsible decision that is right for them. They also spend a great deal of time vetting potential buyers to make sure each dog will be a good fit for their new forever home as well as being transparent about their breeding program and practices. Responsible breeders do their best to ensure a smooth transition to their new home by providing all the information and resources necessary for new owners to be successful, responsible guardians for their new puppy.
