Rainier Dog Resort & Spa

Nestled in Renton, Washington, Rainier Dog Resort & Spa offers enrichment-based boarding, daycare, training, and bathing for local dogs. Owned and operated by Kelli and Sam, a husband-and-wife team with backgrounds in veterinary care and business management, the facility opened in 2022 with a mission to deliver personalized, fear-free care tailored to each dog's individual needs.

Key Services & Amenities

• Private suites and cabins (The Den, The Cabin, and The Loft Suite) featuring solid walls and glass doors
• 24/7 on-site staff for round-the-clock supervision and emergency care
• Indoor and outdoor play yards with a hospital-grade HVAC system and UV air disinfecting
• Full-service bathing, including wash, blow dry, brushing, nail trim, and ear cleaning
• On-site fecal testing processed through Antech with next-day results

Every dog entering group play must complete Rainier's five-day evaluation program, which combines temperament testing, guided social interactions, and confidence assessments to match each dog with a compatible playgroup. This structured approach, paired with twice-daily photo updates and daily health checks, keeps the resort's daycare and boarding programs calm, consistent, and safe.

A Personalized Approach

Beyond group play, Rainier also offers solo and paired sessions for dogs who prefer quieter environments, along with day training, private lessons, and group classes for owners looking to build good behavior at home. The team emphasizes the 5 Pillars of Enrichment — social, nutritional, occupational, sensory, and physical — woven into daily activities like scent work, puzzle feeders, and climbing structures.

Licensed, bonded, and insured by the State of Washington, Rainier Dog Resort & Spa gives pet parents in King County a trusted place to leave their dogs, whether for a few hours of daycare or an extended boarding stay.
