Professional Dog Training, Boarding & Daycare in Brentwood, CA

I’ve wanted to work with my puppy here for so long and finally had the opportunity to join a basic training class. I absolutely LOVED it! The trainer was extremely knowledgeable and professional, and the atmosphere was perfect. I have a Malinois, so training is a must, and I couldn’t have chosen a better place. I loved it so much that Harley and I continued with the e-collar class, which I highly recommend. Alert K9 is worth every penny!

The crew there is amazing. They are always willing to help and answer any questions yiu may have(and I have millions of them) They don't discriminate against breeds. I've seen small dogs to large dogs all playing together. They keep a calm and quiet environment which is helpful if you have anxious dogs. My dog is a velcro dog and this is the only place she will let me leave her, she runs right in without hesitation. She knows her daycare days. They treat every dog like their own and know all their names and quirks. I can go on and on about how great they are. I highly recommend them.

I can't thank Brian and the team at K-9 Alert Training enough. My 4-year-old Lab was completely out of control — no obedience, leash pulling, and easily overwhelmed. I enrolled him in their Board and Train program, and the transformation was incredible. He came back like a brand-new dog: focused, calm, and finally manageable. We followed up with E-Collar training, which not only deepened his obedience but gave me the knowledge and confidence I needed as an owner. The team is patient, professional, and truly passionate about what they do. I now send my dog to daycare there simply because I love how well they care for him. The environment is clean, structured, and positive — and my dog absolutely loves going. If you're looking for real results and a team that genuinely cares, K-9 Alert is hands down the best. Highly recommend!

Our Rottie Kenzo was trained here when he was 10mo to 1 year. Hes 2.5 now and we get asked daily where he was trained, so thought id come back to give a review! He has always been completely off leash. Alert K-9 is highly recommended

ABSOLUTELY LOVE THEM!!!!! Ryan and his staff are so professional, helpful and knowledgable. We just boarded our two “kids” with them; and never worried about them while we were on vacation because we knew they were in excellent care. Our dogs were very happy there too, they got to run around and play with new friends!

We learned SO much in the basic puppy group class! Highly recommend—even if you have a small pup! We implemented what we were learning in class at home, and our puppy really picked up on all the commands. He actually waits at the door when asked and listens to us when we’re training. I feel 10x more comfortable with leash handling. Ryan takes the time to help you with whatever issue you’re having, and it’s up to you to work with your pup. Excited to sign up for continuation classes in the future!

Great job the owner Ryan ( Alert K9 ) trains your dog. Then Ryan trains the dog owners on what the dog has been taught. Really easy, the dog are ready to go and please their owner. Ryan and his staff address any issues you may have with your dog.

Absolutely love and would recommend Alert K9! Very professional, clean, responsible, kind. They love dogs. They love that we love our dogs. I’ve never felt anything but goodness in their classes and facility. I’m confident leaving my dog with them knowing they will be safe and well looked after. We took our ridiculously rambunctious (and adorable) 2.5yr old rescue here when we were at our wits end. And now our pup is amazingly well behaved, a true joy to have around, and a real show off with family and friends. We take her to daycare regularly and are looking forward to taking our second rescue pup there soon.

Ryan and his team are incredible! They have worked wonders with our puppy from he was 6 months old. He understands commands and walks well on leash, no pulling or lunging. Now at over a year old and 130 lbs, he is extremely disciplined and listens consistently. We have no idea what we would have done without them....highly recommended! Kudos to the entire team!

They worked magic on my pup. Coop struggled with basic commands and had alpha dog behavior. However, Ryan was able to help with all of his poor behavior and more. Our little pup has transformed, and we have Ryan to thank for it!! If your dog is struggling with behavior issues, sign into Ryan’s puppy classes, night and day changes.
