Hi all. I have a question. My house pig, Hamlet, loves to be out of his pen, running around with my dog and cats. The only thing is, when he is out, he emits an odor that is not very pleasant. Does anyone know why he emits this odor when he is out of his pen? I thought that maybe he is just excited to be out - happy excited, not sexually. He is an intact male and I have heard that males will do this (someone compared the smell to dirty gym socks). Will castrating him help?
