How do I stop my dog from jumping up at visitors? He does not do it with my
husband or myself.

This is a hugely complicated question that has many answers depending on many variables. First you need to know why he is jumping up at them - what do they do that you don't? How old is he? What breed is he?

Perhaps you could Register and give us more details.

How do you stop him?  By telling him (if he knows the command) what you want him to do instead - 'sit' usually works well - and you'll also need to train your visitors not to fuss him or pay him any attention (including looking at him or talking about him) unless he does as he's told - you'll find the dog is easier to train than the people ;)

I had this problem and taught mine to sit when visitors come (and when we come in as she did it with us too). She only gets stroked and talked to when she's calm. Worked brilliantly. :)

It also helps if you can brief you visitors before hand not to encourage this unwanted behaviour.  All the good training that you do can be pointless if your guests reward your dogs jumping up by responding to it. 

Before I taught Bess to sit when we had visitors, if I said "Bess, get down" or told  them to push her down etc. they'd say "oh she's ok" and carry on fussing her. Now I say "we're teaching her to sit so that she doesn't jump up" they keep quiet and watch her do her "trick" :D

As Digger says the dog is easier to train than the people, but the visitors can learn how to behave themselves eventually . :D
