1-1 Playdate for a strong dog

Looking for a no-leash play partner for a very energetic 1-year-old unneutered Male Rottweiler. The boy’s not aggressive, but very excitable around dogs, and some rough play is expected. Safety is super-important, so our guy will be muzzled at first. We’d welcome any age and gender, but ideally a strong-willed or calm medium/big doggie.
