We cannot say enough wonderful things about Sandy and the care, training, and attention she provided to our dog, Sonny, during his three-week stay. From day one, Sandy treated Sonny like he was part of her own family. She consistently sent photos, videos, and training updates, which gave us complete peace of mind and allowed us to see his progress every step of the way.Sonny came home much more well-behaved, confident, and trained. Sandy also spent time teaching my husband and me how to continue reinforcing his training, which was incredibly valuable since he’s only one year old.Sandy is an amazing trainer and a truly caring person. We highly recommend her for both boarding and training and would absolutely use her services again!

We adopted our mixed-breed dog at about three years old after she had spent roughly two years in foster care. She was a sweet dog, but she had a lot of chaotic energy and very little formal training. While she knew a few commands, she was difficult to manage and we honestly worried whether we'd be able to handle her long-term.We enrolled her in Mike's 3-week board-and-train program, and the transformation was incredible. When he brought her home, the difference was night and day. She was calmer, more focused, and had a solid set of commands that gave us a reliable way to manage her behavior and energy.What impressed us most was Mike's approach. He's calm, patient, and practical. There was never any "dominate the dog" mentality - just simple, consistent training that made sense for both the dog and the owner. He took the time to explain not only what to do, but why it works.Several weeks later, our dog is still doing great, and Mike continues to provide follow-up support whenever needed. In fact, during a recent follow-up visit, she was absolutely thrilled to see him. As owners, that told us a lot. It was clear she trusted him, enjoyed working with him, and had formed a positive bond during training.His communication has been excellent throughout the entire process, and the continued support has been invaluable.I would recommend Mike and Cornerstone K9 to anyone, whether you're a first-time dog owner, have a rescue dog, or are dealing with challenging behaviors. We went from wondering if we'd ever be able to manage our dog to absolutely loving life with her. The difference has been invaluable.

We cannot say enough wonderful things about Jess from Cornerstone K-9! We handed her two terrors that vaguely resembled golden retrievers and she brought our puppies back with actual manners. The transformation is unreal!From the very beginning, she was knowledgeable, patient, and genuinely invested in helping us and our pups succeed. Her training methods were clear, effective, and tailored to our puppies personalities and needs.Not only did we see tremendous improvement in obedience and behavior, but Jess also took the time to educate us so we could continue building on that foundation at home. She was always encouraging, professional, and available to answer questions along the way.The confidence and skills our dogs have gained is truly remarkable, and we are so grateful for Jess’s dedication and expertise. If you’re looking for a trainer who truly cares about both dogs and their owners, we highly recommend Jess and the team at Cornerstone K-9!

Sherman is the absolute best trainer! We have little mates a little over a year old. They needed help with obedience but more urgently reactivity. They had become afraid of nearly everything to the extreme of their own shadows and it unfortunately was leading to aggressive behaviors. At the end of their training Sherman brought us home two happy healthy and confident puppies with a love of learning new things. They love training and are just so much happier all around! It’s clear he was well informed about their needs and helped them overcome so much in such a short time. They absolutely adore him so we know they are treated incredibly well with him and he also shares videos along the way so we can see what they are working on. I cannot really put into words what he has done for these dogs and our family. The difference is phenomenal. There is peace in our home again and our dogs will have a much better life thanks to their time with him. If your family is struggling call Cornerstone K9 to get the help you need! We were doing so many things we had no idea were feeding their anxieties and actually teaching them to be more reactive! Sherman was incredibly calm and patient in educating us as well. We are a family of four and he even put the time in to show our children how to work with the dogs. You will not find better training anywhere else.

Sandy did a wonderful job working with my Doberman, Juniper. She was always very quick and attentive to any questions or concerns I had. When brought home, juniper displayed great loose leash walking skills, in house obedience, and overall great attention to commands. Through personal updates and video updates via her instagram page I never felt in the dark on junipers progress throughout her 3 week training period. Thanks so much, Sandy!

Sandy is amazing! While working with our young puppy, Sonny, she kept our family informed every step of the way and provided great insight on how to help him progress. She was very engaged, answered all of our questions, and showed genuine care for both our new pup and our family. She was also flexible with training dates, and having her work with Sonny in our home was extremely convenient.We highly recommend Sandy — she is knowledgeable, professional, and truly loved by both the dogs and the people she works with! Sonny is very athletic and eager to learn, and we are already considering additional training with Sandy as he continues to grow and develop.

We had a great experience with Cornerstone K9! We were having trouble with our two dogs getting along (boxer and an Aussiedoodle). They would be fine most of the time, and then randomly one would be triggered and start a fight with the other one that was challenging to break up. My family was stressed and losing hope. We didn’t want to give up on them. We had never given a dog away before, but we were getting to the point of considering it and were devastated. Karissa took the younger boxer for a 4 week training. The hope was to try to get her to understand boundaries and corrections form our older dog. Karissa even ended up keeping our dog for a few more weeks to make sure they got the space they needed to have a fresh start. I am very happy to say that after a somewhat tense reintroduction, the dogs have settled in nicely. There has not been an argument between them since she came home, and they have been much easier to manage. It is still a work in progress, but we are very happy with the results!

James from Cornerstone K9 took my intact 2 y/o vizsla for a 3 week board and train. My guy was already e-collar trained with basic commands, but I was struggling with consistency and moving past the basics. Biggest struggle was self regulating, staying in 1 spot longer than 5 seconds, and walking on a leash (would about choke himself out). James training was HUGE for me and my Otter. After getting a lesson with James post training, I’ve been able to continue Otters progress. He is now helping me train horses and trail riding off leash, is able to stay where I put him while I work, and I can leash walk him! I am so happy I can finally take him to breweries and public places! James also helped with beginning stages of resource guarding I was struggling with. The foundation James gave Otter has made all the difference giving Otter and I great relationship!

Very clean store and great selection

Jess was incredible. Reina, who I genuinely thought was untrainable at times, came back a completely different dog. We did a few in home sessions with Jess before boarding and I would 10/10 recommend doing that. Reina is a Xolo, which in my opinion is one of the harder breeds to train, and Jess absolutely crushed it. She was confident, knowledgeable, and honestly just badass at what she does. She made this experience worth it for us.My only complaints are around policies with ownership, not the training itself.First, they tell you to wait until 3 days before boarding/training to do the fecal sample. I would strongly recommend getting one done well in advance and then repeating it closer to the stay if needed, especially if you’re someone who takes your dog to the dog park often. It saves a lot of stress if anything comes up unexpectedly.Second, the refund policy is very strict. Any time we needed flexibility, it was eventually approved, but the first response was usually offering account credit instead of a refund. Considering the amount of money being invested, that didn’t make me feel very comfortable.Overall, Jess did an amazing job and I’m extremely grateful for the work she did with Reina. My advice is just to read the contract carefully and don’t book anything unless you’re 100% sure you’ll need it or have already run any questions and your exact scenario by the owners. We have an older dog with health issues that they ultimately were not able to accommodate after we had already booked, and if we had discussed everything beforehand, we likely could have avoided having to go through the refund process.

I highly recommend Cornerstone K9 and Karissa! We sent our boxer mix Cooper to their 5 week board and train to help with his reactivity, anxiety and overall manners and he returned a changed dog. His progress has been incredible. Before he would freeze on walks in the presence of other dogs or people and now he’s much more confident and passes by with barely any trouble. The biggest change has been his behavior in his crate. It used to be stressful for everyone when trying to get him to go into the crate when we’d have to leave the house or for bed time but now he goes in no problem. Lately before bed he even goes in all on his own! I can’t thank Karissa and Cornerstone K9 enough for all the work they have done for us and Cooper!

A Big "thanks for making her worse" to this company. Sent my Cane Corso there for 4 weeks and had to beg for updates on her progress. No pictures, video on her progress because they did absolutely nothing for her. Reactive issues was the main focus for sending her and they made all these promises that they could help her. I was told they could not take her on outings because they didn't know how to get her into the van to travel???? These are professionals???? They locked her in a kennel and did no training at all. What they said they taught her she already knew. Now the trainer with SPCA is working with her to undo what she was subjected to while in "professional training ". NEVER SEND YOUR DOG to this company, they will take your money and make your precious one worse.

I could not be happier with our experience with K9 Cornerstone! From the initial call, to the trainers, to the communication and support following our doodle’s return home, everyone was professional, supportive, and truly seemed to genuinely care about us and our dog! Due to unforeseen circumstances, we had to change trainers from Kaitlyn to Sandy mid way through our train and board. However, this was communicated immediately with us. Everyone made sure we understood and were comfortable with the transition and that our dog’s training was uninterrupted! Both Kaitlyn and Sandy were wonderful! In the few weeks after Lucy’s (our doodle) returned home, we had a couple hiccups in her behavior. Sandy was quick to help and even pull in an additional trainer, Sherman, to be sure we got everything sorted out! Don’t hesitate to use this company! You will not be disappointed!

We're so happy to have our pup back home and such a change in him! He's obedient, not finding things he shouldn't and playing hide and seek, and has become a quiet gentleman. He listens, obeys and isn't jumping or biting anyone. Sandy has been so great in teaching him and us to become a working team in Kaos' training.

We had such a wonderful experience with Cornerstone K9 and their training team! From the start, you can tell how much they truly care about the dogs and the families they work with. Sandy, our trainer was incredibly kind, patient, and knowledgeable, and made the whole process feel comfortable and positive for us. We saw such a big difference in our dog—not just in behavior, but in confidence too—and it’s been so rewarding to see that growth.They also took the time to guide us as owners, which made a huge impact. We feel so much more confident continuing the training at home. We’re beyond grateful for everything they’ve done and would wholeheartedly recommend them to anyone looking for a caring and effective training program!

Very happy with our experience! Jess has been so helpful training our Newfypoo puppy. Highly recommend her!

High quality all natural dog supplies that you can’t find anywhere else in the Triangle. Extremely friendly and helpful staff — Steve and Jeff are great! Highly recommend for all dog owners.

Let’s Start with Me: I’ve fostered 40+ dogs. I’ve seen and done it all when it comes to dog behavior but I reached a point where I knew I needed an expert. My personal dog caused my foster dog to bite me and I struggled to get a trainer to listen and consistently help.Cornerstone came recommended from another foster so I put in a consultation request. Within a few days I had an hour long phone call with the owner Gina who said she would’ve fired the trainers I had dealt with before for their behavior. She thoughtfully placed me with James who was a former foster who’d been through a dog bite so I felt like he knew where I was coming from and where I wanted to go.James worked with the foster dog who bit me for 4 weeks and me and her adopter are so grateful. He got her to be comfortable around other dogs. She previously refused to go on walks but now easily went on a 2.5 mile walk. Everyday, she blows us away with what she’s learned.James worked with my personal dog for 3 weeks and she’s not perfect but she is so different. The day James picked her up I had to essentially hog tie her to do a sanitary cut and she nipped me multiple times. Now she easily accepts brushing and routine grooming. She responds to the e collar which gives us a hands free way to control her which is invaluable for future unpredictable interactions with fosters.Do it. Book the consult. Pay the money. Cornerstone is intentional with training and so worth it.

The admin staff is wonderful, as is Jess who was my dog's trainer. They really listen to what you need and then match you with a trainer. Jess listened to my behaviorial concerns, incorporated them into her training and then explained "remedies" very carefully to me when my four year old bichon was returned home. An extra bonus was that he really liked her! I especially appreciated how she trained me to reinforce the good behaviors and correct his missteps. After two weeks with Jess, he and I have a plan to keep those good behaviors in place.

This is great place to get all your dog needs. Really friendly staff and owners!!
