My Shih Tzu has gotten aggressive in the last five years. I am thinking of putting him down, but I don’t know what to do. What’s your advice?

My 3-year-old Chihuahua, gets along fine with my children and me, but he hates my husband and tries to bite his feet. My husband is even considering getting rid of him. How can I make them get along?

My 6-month-old puppy has taken her love bites a little too far. Any ideas on how we can make her stop?

How do I get my Weimaraner to settle down and listen to me?
