RIVER is 45 pounds of pure joy and love ‰%9D%A4. This 4 year Boxer mix has been through some stuff...so he can be a little shy at first, but oh my goodness, once he knows you...you won't find a sweeter, more affectionate boy. Despite his tough guy appearance, RIVER loves nothing more than sitting on a comfy lap. RIVER came to us heartworm positive..but now he's all clear, neutered, and healthy as can be. RIVER has had some dog friends, but really would be best as a one and only.
