We always know our pups will be safe and supervised when they head over for a fun day of daycare! The staff are always friendly and outgoing, and they do such a great job coaxing shy dogs out of their shell and making them comfortable. Love that play groups are tailored to behavior and size, so nobody gets overwhelmed or feels bored. Their boarding is fantastic and it's a great feeling knowing that our dogs will be loved on and looked after, and the report cards after their stay are fantastic!!


A big thank you to Becky and the entire staff at K9 Kaos. We were able to book a five night boarding for our 3 year old lab Annie. We were concerned due to Annie's separation anxiety, barking and reluctance to eat in the past. Upon picking her up we were pleasantly surprised that she looked great, and those issues did not occur. We will definitely be using K9 Kaos in the future and recommend them to all our family and friends.


What an Amazing Facility!! My little Yorkie girl Lexi loved her first day! The Staff are so friendly, professional, knowledgeable and obviously have a love for animals. They post daily photographs of all the Doggies at play. They all look so very Happy! Lexi also received quite a generous welcome bag that also contained a report card!! Lexi will be a regular here at K9 Kaos. Thank you all for taking great care of my fur baby.
