More: Gunner is a rescue from Rotts of Friends we think he is around 4. We like to rescue older dogs to give them a secure life as the age but somehow Gunner fooled everyone. We were told he was 5 a year ago but after a couple of weeks we were doubtful and our vet confirmed our suspensions that he was much younger. We love him and are enjoying the energy of a younger boy. Our 10 year old chihuahua? Not to impressed🤣
