I'm Karen M., the breeder behind Karen Marr located in Laramie, WY. Our puppies are raised in our home as part of our family, where they are surrounded by the sights, sounds, & daily activity of a busy household. They are lovingly socialized around our 4 children, ages 4–17 (and their friends :) ). Puppies will receive Early Neurological Stimulation (ENS) from days 3–16 to provide early experiences during an important stage of development. Both parents are cherished family dogs with wonderful temperaments, athletic builds, & a strong bond with their family. Our dam has been genetically tested through Paw Print Genetics & is clear of the Boxer-specific conditions, with no carrier results. We put a great deal of love and care into raising each puppy & want them to leave us feeling confident, loved, & ready for their new families. Each puppy goes home with food, a blanket scented with mom and littermates, & toys to help make the transition a little easier.
