Wholehearted Canine

WHC Founder & Trainer


Sarah Singler

I am a Certified Professional Dog Trainer through Absolute Dogs, and I continue my education through other Absolute Dogs courses and memberships. I am a Professional Member of the Association of Professional Dog Trainers. I graduated from Baylor University in May 2017 with a Bachelors of Science in Biology. I have loved animals from a very young age and have a passion for helping dogs modify their behavior to enjoy a fuller life alongside their families. I am always in pursuit of expanding my knowledge of dog psychology and behavior patterns and enjoy designing creative solutions to apply that knowledge in eradicating behavior issues. 


My Dogs

Both of my rescue dogs joined our family with serious baggage and behavior problems resulting from their past. They are my inspiration to help other dogs overcome the odds and achieve enviable behavior through wholehearted training. Pictured above is Bristol, and to the right is Daisy.



All private training sessions take place in your home. Fill out a pre-evaluation form below, then schedule an evaluation visit to get started. We will discuss your goals and your dog's needs, and I will construct a custom training plan. Book sessions as frequently as you like, and make use of tools and instructions to reinforce training between sessions.
