Hello all I have an 8 year old sheltie who I am looking to stud. It would be his first time and I just want to be sure he will be safe doing so. I have done quite a bit of preparation in getting him tested for brucellosis and a full physical which both have come back healthy. Are there any concerns I should have or does anyone know of typical injuries that could occur? This is always something I’ve wanted to do but not at the expense of a serious injury. Thank you all so much for your time
