I had my golden retriever chemically castrated as a puppy, around 6 months old if I recall correctly, on my vets advice. He was completely out of control, aggressive, disruptive etc.and beyond training. He was kicked out of puppy training school for being too disruptive. To have him chemically castrated was the best decision I ever made regarding his care. It turned him into the most lovable, comical, bouncy puppy that I could ever have wished for. He was loyal, beautifully behaved, loving and had the most wonderful personality throughout his entire life. He survived until he was 15 years old and we gave him the most wonderful, loving, pampered life that he deserved. I have never felt so much unconditional love, which he gave me and I have never felt such love again in my entire life. I still grieve for him daily and he passed away 14 years ago. My life has an empty void where he belonged. I would highly recommend this procedure as it completely changed my Josh’s personality for the better
