I am worried a lot. Pet's info: Dog | German Shepherd | Male | unneutered | 1 year and 5 months old

No, taking antibiotics, even a lot of them, does not decrease the life span of your dog. Unfortunately German Shepherds are a breed that has a lot of medical and congenital problems. The fact that he keeps having infections points to a problem with his immune system, ie , that it is not working very well. You may want to discuss with your vet whether Bruno's immune system could be boosted and how. This is different in every animal and depends on the individual condition, therefore it is best to discuss this with the veterinarian who knows him best.
