Apollo, has been taken care of by Dr. Hagan since I brought him in for his 1st Puppy Shots. He diagnosed his Sensitive Digestive System. Thank You Dr. Hagan. As Apollo grew, I believe that a few of his Assistant's became fearful of Apollo. Apollo can be Agressive, if he becomes Fearful, Anxious or Agitated. During COVID , when owners couldn't enter with their Pets, Apollo was most Anxious. Our Instructor at Dog Academy, evaluated Apollo and determined, he is not an Agressive Rottweiler. And he and I have done quite Well there.
