Customer Reviews
Marnie has a wealth of useful knowledge, and is very patient with new dog owners .She is very responsive. - Halethorpe, MD - October 2025
- Daniel PMarnie of Joyful Dog is the most positive of positive trainers. Our two tiny shy dogs simply adore her. My boy dog (who loves training) learned so much via his online courses during the pandemic. I feel like he's a little genius Einstein pup. Every time they hear Marnie's voice they wag and wiggle like crazy and get so excited, then they focus like excellent little students. She's also great about training us humans how to treat our dogs respectfully and speak their own language to them. 10 stars! - Ashburn, VA
- Suzie CVery knowledgeable and patient. Marnie really helped our dog and us. I have learned a lot and have a very different way of approaching things now.
- Ewa RMarnie and Susan are excellent trainers: very knowledgeable, thoughtful, and helpful. Love their classes!
