My pup is 12 weeks old, and yesterday had his first day with the schutzhund trainer. When my pup met the trainer he peed. I have noticed that he does this when he meets men. When strange men come to our house, he has not done it. I dont understand why since I have a husband, and we got him from a male breeder. Is this normal for a pup this age? The trainer said he usually sees this in females because they are more sensitive and to have more men handle him. Any thoughts?
