FOR A HAPPY HOUSEHOLD

"A great experience! Six lessons packed with training, fun, informative insights, and nutritional tips. My husband and I enjoyed these lessons as much as our Cavachon did. We are proud graduates as of today and are hoping to join the next level class to have an even better behaved dog."

Just finished training for my 3 yr. old Panda who graduated this evening. Mary’s professional approach, and training methods were phenomenal. First of all, she had to train me, then we trained Panda to a level I didn’t think was attainable. Mary’s skills, and results exceeded my expectations. We are entering Panda in the Level Two training offered by Mary.

Wonderful experience. She really helped our puppy come out of her shell. Great first start to training. Mary was amazing!

I highly recommend Mary, not only is she a great trainer, but while she is teaching the class she takes the time to focus on the individual needs of each dog.

1 week after we brought our 10 weeks old Sheepadoodle home, we enrolled in Mary D’s dog training classes.
We just graduated from her 2nd series for a total of 12 sessions … I can’t begin to thank her for all her guidance. Her experience has been priceless. We’ve already signed up for her next session of classes

So glad I meant Mary. I’ve had dogs my whole life and own/operate a Doggy Daycare. BUT I didn’t know as much as I thought. Mary is very knowledgeable on how to get the pups to do what you want. My Korbin and I just completed class 1 and I’m looking forward to completing them all so my boy can hopefully bring joy to many sick people in the future. Thank you Mary!

I took my 8 1/2 old Maltipoo “Houston” to Mary’s class and was so impressed on what she was able to teach both my baby and I. He picked everything up so quick and I have to thank you Mary for all your help. I have already told a bunch of my friends about your class for their dogs and Houston and I look forward to the advance classes. I am so happy from what he has been able to learn. Thank you thank you thank you. I would recommend signing up for Mary’s courses if you are considering. You won’t be disappointed . See you in the advanced class Mary!

Mary is a wonderful trainer and understands the needs of your dog. Mary is well prepared and taught us how to retrain Gracie in different situations. She is a very knowledgeable and is great with dogs! We will be returning to Mary for more training. Thanks

Mary has worked miracles with my chocolate lab, Sammie and both my husband and me. Because of her, Sammie is a different dog. Not only do we notice how much more calm, mannerly and obedient but, family members, friends and our neighbors can not believe the change in Sammie since taking classes with Mary. I would recommend Mary to anyone with any breed, she truly works miracles and cares very much about the animals and people she trains. Thank you Mary!!!!!!

We so enjoy working towards being a good dog and we have fun doing it. Mary is so patient with the pups and the humans. We need to learn too. I like this trainer's methods. She is so very interesting to watch and listen to when at class and her stories are always interesting. My pup, Brida, will do anything for Mary. Thank you, Mary D.

Mary was so knowledgeable to us. she was so helpful and had lots of ideas that helped us with Lola who was shy and had a mind of her own. Lola actually started to look forward to her training days and came out of her shell a lot. She has calmed down a lot and listens to us now. Hoping to start phase 2 soon. Wonderful person and very pet friendly.

Mary is an amazing trainer! She was the best thing to happen to me and my crazy lab, Daphne. Without Mary's training expertise and unfailing patience, Daphne would be a much different dog today. She saved our lives, I assure you! She helped turn my obstinate and out of control rescue into an obedient and willing student. I've seen Mary reach the most seemingly helpless cases. As soon as my husband and I got our second dog, we called Mary. Thank you, Mary, for the huge differences you've made in our lives and the lives of our sweet girls.

Mary is AWESOME! I would recommend her to everyone!

Mary is absolutely incredible! Not only does she loves what she does, she is so knowledgeable! Our girl Brooklyn learned so much and loves going to class. We just finished level 1 and plan to take level 2 . Highly recommend Mary D’s!
-Melissa K
She takes training your dog to the next level! Love the classes and her knowledge, 5 star rating!

Mary has done such an amazing job with our 5 month old husky/German shepherd. She was so shy and did not want to listen to anyone. She just graduated even with distractions of our 1 and 2 year olds running around. The love and passion that she has for her clients is amazing. Cannot wait to see what level two can do for our little girl 💕 Thank you Mary for your help

I took my three-month-old Shih Tzu bichon munchkin for Mary’s class and I found her to be exceptional in all characteristics of a great teacher and Trainer I recommend Mary to all

Mary D was awesome ! Not only did my dog learn a lot but I learned a lot as well! She is a great trainer and I highly recommend joining. She created a positive atmosphere where my dog could learn and have fun!

I find it super difficult to write this review. No, not what you’re thinking, this is not a negative comment. My dilemma is that I cannot come up with the right words to describe Mary D and her dedication to K9 training. Her knowledge combined with her genuine love for helping dogs (and the human at the other end of the leash) is truly an amazing thing to experience. I had this experience taking a Puppy Obedience class. Her training has literally changed my perspective on what is possible. I’m so excited to move on to the Level 2 class and more. If you’re on the fence on signing up, DON'T WAIT. You and your fur baby’s life will forever be changed for the GOOD!

I said I needed to take Pearl to obedience school so I could learn, and Mary is a great teacher! Pearl is very smart, and we learned the basics together, with lots of instruction, tips and encouragement from Mary. Her love for the animals is obvious, and she’s great with not always coordinated humans too! We will be back for more classes in the fall.

Mary is an amazing dog trainer. She really understood our puppy and his training went so well. I cannot imagine a better dog trainer. She teaches the skills to practice once we leave and it has worked! Thank you Mary!

Mary D's Dog Training was a great learning experience for my 9 month old pup. We both enjoyed, learned much and made new friends. And after training initially through Petsmart, I highly recommend her training style.
- Yolanda N.
I LOVE my dog and if the service and attitude were not great I would not be there. Mary is wonderful and makes you and your pet feel at ease. My pup has learned so much in just her first few lessons I can't believe it. I highly recommend.
- Teri Nichols
After attending one dog training class BEFORE finding Mary, I was able to clearly see the difference in styles. Mary makes the training fun and engaging for both owner and pet. My Rosie has gone through 5 different training classes, and she loved them all (and loves Mary, too). She will be 6 soon and still is the nicest, sweet, well-behaved dog and loves to continue the (learning) games we played in Mary's classes over 5 years ago. I highly recommend Mary for her outstanding skills and patience.

Highly recommend Mary's training! My dog is unfortunately dog reactive (he just wants to play with every dog) and I never thought CGC would be a possibility. Mary worked every week and gave clear directions of ways to help set your dog up for success. I never realized how much my emotions affect my dog! She went above and beyond and we met outside of class to work on supervised separation. She truly cares about you and your dog. The best part was that during his CGC test, the dog interaction was the easiest part for him to pass! We can't wait to continue training with Mary! If you want a fantastic trainer who really understands what is going on with your dog.....look no further!

Mary was so great with our little rescue dog Lewey. He really learned a lot in just 6 weeks. She was very thorough and patient. I would definitely recommend her for any dog.
- Deborah P.
Mary is absolutely wonderful; she took my traumatized German shepherd and transitioned him into a happy and obedient dog in just over two months! Couldn’t have done it without her! Thanks Mary
- Stephen V.
What an amazing dog trainer. We took our miniature pincher puppy and out 6 year old rescue. They both did amazing work with basic commands. Our rescue was very anxious and was afraid of all noises before the training. Now she plays with our new puppy and the miniature pincher and is no longer anxious.

Mary D is a fantastic dog trainer. Our Dulcinea was in an Adolescent Obedience class with three other girls and by the end of her 6 weeks she was so much better behaved and also more socialized. I highly recommend Mary.
