What our customers say about us

“Derty Dog Fitness is a welcomed addition to the Brentwood dog families.  Haley and Colt provide excellent one on one care for my dog.  Colt is very knowledgeable of dogs and specific breeds.  The excellent care my dog receives when dropped of sets my mind at ease that he is being cared for as if he was a member of their family.  Their ability to board as well as exercise my dog was the selling point for me.  This is a small family run business and I have recommended them to my local Brentwood friends who have active dogs.”

“I've been taking my dog Dungey to Derty Dog Fitness for about 4 months. I've experienced other boarding facilities and am beyond happy with Derty Dog Fitness. They are great with my dog and Dungey is excited to go to daycare each and every time. Dungey goes to daycare once a week and when we leave for a few days he is boarded there. Derty Dog Fitness has become our dogs home away from home. “

“My name is Cheryl and I live in Tracy. When I decide to go on vacation and need to board my dog, I always use Derty dog fitness. They are always very professional. My dog is always exercised & fed properly. They make sure they get to know your dogs personality, and use judgment for the dog as an individual. I have been there on several occasions, and any dog in their care has been well kept. I look forward to what this place has planned in the future. This will be a great asset to the community.”

"Derty Dog Fitness is a wonderful facility. I have been bringing my dog Queen here for about 2 1/2 months now and me and her love it. It took her literally a few days to get use to the place and the treadmill, because Colt the owner is so good with dogs that Queen couldnt resist and just loves coming here everytime. I try to bring Queen depending on my schedule about 2-3 times a week to do the treadmill to help with her leg since she had knee surgery, and its been helping and also gaining back her muscle mass. The owner is great at checking her out periodically to make sure she's doing well. Being a Veterinarian Technician I am very picky with what facilities I take my dog to and who watches my dog. I want her to have the best care and also because shes a big girl (Great dane). The owners Colt and Hailey our wonderful with her and she and I trust them. Queen has stayed here for daycare a couple of times now and does great and she even gets her exercise on. if I ever needed her to stay overnight I would not hesitate.  This place is great for dogs in need of excercise that need to be doing something like a job, and especially if you may not always have the time to take your dog out for walks or playtime. If you have not checked out Derty Dog Fitness go do so. The owners are wonderful, knowledgeable, and have a heart for animals."

"Colt and Haley of Derty Dog are absolutely amazing and took very special care of a very special needs dog. They kept me updated on him all the time and eased my weary mind and emotional state of mind. I dont know what I would have done without them. Thank you again for your amazing care of Kilo."

"5 star for sure!  Colt and Hailey are very accommodating to our needs for rescue and transport.  Educating us all the way! Highly recommend for a weekly exercise regimen of the over zealous pup! Derty Dog Fitness has now cared for 2 of our foster dogs and these pups could not be happier!  Great people, big hearts, and true animal lovers! Thank you for all the help!"

"We also, had never boarded our dogs before, and were nervous about how they would do or if they would be treated well.  After meeting with the owners Haley and Colt, we were put a lot more at ease of leaving them in their care.  They are such awesome people, and the dogs LOVE going to play.  It's a bit out of the way, for we live in Pittsburg, but it's SO worth the drive. Derty Dog is definitely not your typical dog boarder, they're so much more interactive and provide a great environment for all dogs. We will definitely continue bringing our pups to them knowing they'll be well taken care of and having a blast :)"

"I have never left my dog, Boomer, with anyone over night before and I was a bit nervous the first time overnight. I met with the owners of the business and they both made me feel very comfortable about my decision to have him stay with them while I went out of town. A very fun atmosphere for the animals and the staff is very friendly and knowledgable. I absolutely plan on coming back should I ever need to leave him overnight sometime in the future. Thank you to "Derty Dog" for keeping my pup safe and giving him an excellent dog workout!
