I had the pleasure of working with Mara from Copper Hill German Shepherds to gift my daughter her favorite dog, for her 13th Birthday. Mara gave consistent updates on Gunner’s milestones and appointments. When it came to picking him up she worked with me to pick him up pending a coming snowstorm and met me half way. She has been an absolute pleasure to have met and work with, Gunner is in perfect health and adjusting well with his new family and we all love him dearly. Mara’s early training has help greatly with this frigid cold Gunner is potty trained to only go in his pads and has had few accidents. Again I can’t say how great it was working with Mara.

Mara was amazing! Great communication and very informative/sweet with information on her dogs and puppies! We really loved working with Mara and meeting her. She really took her time with the puppies, especially with potty time and introducing small commands! Our girl is just the sweetest and smartest. We couldn’t be happier and we wish Mara and her family the best of luck with their future litters!

It was exceptionally well working with Mara. Her response time was really quick. We had no problem setting up a time and place to get our lovely boy “Terrain” who’s the best doggy EVERRRR!!!. Whenever the time should come and i’m looking to expand my family a bit more i would definitely be going back for another puppy with Mara. Thank you once more Mara!
