Mounting problems

Question
I have two male neutered dogs.  One is a 6lb yorkie and the other is a 14lb terrier mix.  Lately the terrier will go to the yorkie and lick him all over then he will jump on him as if he were a female and try to mate.  The yorkie is about 5 yrs old and the terrier is about 13 or 14 yrs old. My husband is afraid that the terrier is going to hurt the little yorkie. My husband thinks that the terrier is actually penatrating into the yorkies anus but I haven't seen it.  How can I stop this?  Is he trying to let the yorkie know that he is the dominant one?
My husband can't stand to see this going on and is talking about getting rid of the terrier.  Please help me if you can as soon as possible.

Dear Wendy

It's impossible to diagnose behavioral problems by email but I can give you a starting point. Yes it is concerning that your terrier is mounting the yorkie.  But lets not look at this one behavior.  Rather lets  consider the relationship you have with your dog.

I will give you the best source, I know of, to help you answer your  question. You need to be aware of the three main causes of dog behavior problems in order to help him. They are improper training, improper relationship and lack of training.

You will need to undo what the previous training has done with reprogramming. Dr. Meisterfeld's book Jelly Bean versus Dr. Jekyll & Mr. Hyde explains rage type behavior the detrimental effects of improper training techniques. Too retrain him I recommend the book Psychological Dog Training by C.W. Meisterfeld. Check with your local library for the books or do a C.W. Meisterfeld search on the web.
