Testimonials
Stella was instrumental in us being able to adopt Khaleesi from the breeder. She is an absolute gem when it comes to dog training. Her patience, knowledge, and dedication have made such a difference for our family. She doesn’t just train dogs–she empowers owners with the tools and confidence to succeed. I couldn’t recommend her more to anyone looking for expert, compassionate help with their dog.
– Client
It’s hard to put into words how much Stella has helped me with my Giant Schnauzer, Ronin. I first connected with Stella through a Facebook group for grooming Giant Schnauzers, and I truly hit the jackpot. Her expertise in all things dog-related is unmatched. Thanks to Stella’s guidance, Ronin and I have achieved multiple titles in dog sports and obedience.
– Client
I asked Stella to help me train my Large Munsterlander, a hunting dog, for basic obedience, and I couldn’t be more pleased with the results. Stella was fantastic from start to finish. She came to my home to begin lessons right in our neighborhood, which made the training convenient and practical.
