I just brought home the newest love of my life, Sadie, whom I purchased from Dale and Judy. My husband and I did extensive research before making the decision of which breeder to go with. Dale was responsive on my first inquiry and then once we put the deposit down he continued to send photos and updates until we picked her up yesterday. We drove from Nashville to get her and she is amazing. I highly recommend Cavaliers of Castlemar and am sure I’ll be back for another in a year or two.

Thank you so much, Dale, for Alfie! We brought him home a little over a month ago, and he has been absolutely amazing. My husband and I both love him so much! It's easy to see the love, care, and dedication that Dale puts into raising his puppies. Alfie has the best temperament - he loves everyone, is a champ during bath time, and is so incredibly trusting. One of our favorite things about Alfie is that he'll bring us his bully stick to hold while he chews it. (After all, why hold it himself when he can get his humans to do it?) He then gradually transitions from chewing while standing, to sitting, to lying down, and then finally when he gets tired, he rolls onto his back and keeps chewing away. (See the pic!) When we first shared photos of Alfie with our family, they all said he looked like a stuffed animal and couldn't believe he was real. After meeting him in person, they said he was beautiful. We're so grateful to have Alfie in our family. Thank you again for giving him such a wonderful start in life!

My wife and I recently adopted two brothers, from Cavaliers Of Castlemar. These Cavalier King Charles spaniels are an amazing breed. Must be the best dog for people that love, affectionate animals. The breeders Dale and Jane are amazing and treat the puppies so wonderfully. Their pedigree is the finest and very well respected in the AKC world. We brought them home after 10 weeks and they were already trained to go potty outside. We did extensive research on the breed and also finding the proper Breeder. We got multiple recommendations and confirmations that Cavaliers Of Castlemar is an excellent Breeder and highly respected. We couldn’t be happier with the dogs, their upbringing to date and the Breeder. Dale and Jane are also available after the adoption for questions and wanting updates on the progress of the puppies. BTW, we adopted two brothers, that are tricolor. They are Winston and Edison of Castlemar.

Yesterday we picked up our FOURTH pup from Cavaliers of Castlemar, and I truly cannot say enough wonderful things about Dale, Jane, and their program. From the very beginning, Dale has always been amazing to work with, knowledgeable, responsive, and so clearly passionate about these dogs. The health and temperament of the Castlemar bloodline is incredible. Our vets are always genuinely surprised at how healthy our Cavaliers are, which says so much about the care and intentional breeding behind them. Beyond that, these little angels have brought so much love, laughter, and happiness into our family over the years. They are sweet, beautiful, affectionate, and have the best personalities. Dale & Jane, thank you for what you do. We honestly hope to never not have a couple of Cavaliers of Castlemar fur babies in our home. ❤️ Sharing photos of our current three for cutest overload!

We just brought home Benny, our first puppy. Dale was a pleasure to work with - transparent, responsive, and kind. It is clear how much love and care Benny received when he was with Dale. We love Benny so much already and we are so grateful for Dale.

We are absolutely in LOVE with our little Rusty! He has the best personality and is so smart!!! Dale was hands down amazing with the whole process! When we went to pick Rusty up he had all of his paperwork, microchip paperwork, AKC info, contract etc ready to go. They also give you the cutest “going home” gift bag with all his essentials, toys, and a starter kit of dog food! He is also very adamant on letting you know he’s available for questions or concerns even when the puppy has arrived at its new home! I will definitely buy another Cavalier from here! Dale is also very knowledgeable when it comes to this breed! Very trustworthy! Thank you Cavaliers of Castlemar for giving us the best boy we could ask for!!!
