Tandi Keen (Keen Boxers)

Tandi Keen (Keen Boxers) is a boxer breeder in Sterling, CO, Logan County and the eastern plains near Denver. She has been breeding boxer dogs for several years and maintains membership in recognized breed clubs, following recommended health tests such as hip evaluation and cardiac screening. Her litters are whelped in a clean, climate-controlled area and are introduced to balanced nutrition under veterinary guidance from an early age.

Her adult dogs live indoors with the family and enjoy daily supervised play in secure, fenced yards. Puppies begin crate training and basic obedience in the main household to support social development. Clients appreciate transparent updates on health records and social milestones, and each pup is vaccinated, microchipped and provided with a starter care packet before joining a new home.

Her breeding program emphasizes stable temperaments suited for family life and canine sports. Families often note the dogs’ adaptability and affection in varied settings, which reflects her focus on early social enrichment.
