Dog Trainer/ Dog Behaviorist

Jacquelyn Court is a highly experienced dog trainer and behaviorist with an excellent track record in handling anxious dogs. While armed with a degree in Communications, Jacquelyn always knew she wanted to work with dogs as an adult.

Jacquelyn is naturally outgoing. She displays the same attitude when helping her clients through behavioral coaching. She exhibits incredible patience in teaching and guiding dogs to conduct themselves accordingly. Her training method allows dogs and owners to understand one another better. For Jacquelyn, training is not only  for dogs but also their owners. She furthers that each owner must understand their dog’s body language to communicate and build a good relationship with them.

Jacquelyn is determined to work with individuals looking to establish an excellent foundation for their puppies. She takes a particular interest in helping anxious dogs overcome their uneasiness. Inspired by the great feedback she gets from clients whose dogs have made significant progress in training, Jacquelyn continues to work hard to make the lives of dogs and their owners easier.

Jacquelyn grew up surrounded by and was raised with three dogs for most of her childhood. Today, she takes care of her dog Blu who has been with her for three years. Blu used to be a mental stimulation type of dog, but Jacquelyn describes him as calmer now that he’s older. For Jacquelyn, being around dogs and helping them grow is a dream come true, a giant leap of faith she knows she will not regret. 

Ashley Demichele

Dog Trainer/ Dog Behaviorist

Ashley Demichele is a passionate, professional, and experienced dog trainer who has grown up around animals all her life. This has inspired a burning love for all kinds of critters, but dogs have an especially huge part of her heart. This love is shown every time she trains dogs, which allows her to create unbreakable bonds between fur parents and their fur babies.

Ashley’s work ethic and dedication when training dogs have consistently produced excellent results that always satisfied dog owners. She understands the needs of the dogs that she trains and focuses on ensuring that their unique situations are always her top priority.

This has led to major changes and improvements when dealing with cases that involve fearful or anxious dogs, as well as the typical obedience training programs. Ashley also makes it a point to talk to clients to truly have a good grasp of what they want and what the problem with their dogs is. Her personable nature and honest approach help to reassure dog owners that their dogs are in good hands.

Other than dogs, Ashley has also spent a lot of time around other animals such as goats, horses (which she rides), pigs, and chickens. She even moved to Utah to work on a ranch.

Ash Rose

Dog Trainer/ Dog Behaviorist

Ash Rose is a highly accomplished dog trainer and behaviorist with a pristine record of successfully dealing with issues that involve embarrassing or undesirable behavior.

She specializes in dog behavior modification and therapy work. She trains dogs to provide companionship to owners suffering from anxiety and other psychological disorders. Ashley has also proven remarkably adept at handling stubborn dogs by curbing their more undesirable habits and poor impulse control.

A huge part of Ashley’s success in many of the cases brought to her attention is the formation of strong bonds between dogs and their owners. She did so by establishing excellent communication and trust, along with involving dog owners in the training of their dogs.

Her ability to communicate with and facilitate the wishes of the clients with regard to their dogs has also earned her significant praise from owners. The huge number of positive feedback she has received throughout her career says everything about her considerable skills as a dog trainer.

Ashley’s love for dogs stems from her own traumatic experiences that were alleviated when she rescued her first canine companion, Whiskey. This was also the period where she developed a huge appreciation for music, which she uses for therapy. Recently, her family was joined by a piebald pit named Gambit Ragnar.
