My 3-month old fluffball growled at my husband the very next day I brought him home. It turned out he was a resource guarder, and he didn’t like his toys taken away or being touched while chewing his toys. During the private session with Maggie, she showed me step by step how to work on desensitizing and counterconditioning his reaction around toys. She also showed me a variety of strategies I could use if/when he got hold of things he shouldn’t. The 2-hour session was packed with useful information, and videotaping the session allowed me to review and practice techniques Maggie taught me later on. After 2 months of daily training, I am happy to report that my pup wags his tails when I approach him while he chews his toys, and he happily drops his toys when requested. If your dog is having behavioral issues, I strongly recommend that you consult with Maggie. She is a knowledgeable, experienced, and highly skilled trainer. She is also kind, personable, and professional with excellent communication skills. She is a force/fear-free trainer who uses positive reinforcement to address behavior issues, which is shown to be safer and more effective than punishment-based training methods in scientific studies. I know it is stressful to have a dog with behavior issues, but effective training techniques can, and often do, mitigate or even eliminate problem behaviors. Give Maggie a try—she is one of, if not the most qualified trainer in the area.
