Dogs will be dogs, i.e. for some reason they really really really like people, and they are just happy......like.... ALL the time. Unfortuately their display of liking someone can indeed be embarassing at times (you get my meaning...we all been there). Lol

Before company arrives you can put them in a separate room like the master bedroom or basement, but a must preferred method is obedience school

We use baby gates to confine our two dogs to areas away from the guest until all are settled. I believe I have also seen adjustable indoor fence type units - sort of like a large playpen that can be set up. Something like this: http://www.cuddledown.com/itemdy00.aspx?t1=Z1627+919+01+01&srccode=NXCZC6&utm_source=froogle&utm_medium=pla&utm_campaign=2014&gclid=Cj0KEQiAz7OlBRDErsTx47LKz-8BEiQAY0OlYjZ0GAadznwvvFimeh8i3TbIuIrQI_5DYc97Zo1M0vYaAvbC8P8HAQ

Do a search for "indoor dog gate"

An attractive baby gate can keep the dogs to one area. But, this may sound weird (I'm a huge dog lover). My "Peanut" and beloved passed Sheppard "Annie" will calm down as soon as company will "acknowledge" their presence. I'd ask my friends to "Please say Hello to, Annie" so she'll be quiet and it worked! I'm not sure if it was because they said her name so they must be "okay" or she wanted to be "acknowledged" as part of the family. lol

Another suggestion is to use aluminum foil kinda loosly wadded up across the area you want them to stay back from. Our dogs don't like the noise it makes if they walk on it. A piece laying on couch or chair also keeps them off certain furniture. I've also heard about using a piece of the plastic protectors used under a rolling chair that have those nubby bumps on the bottom, lay it down with bumps up, they don't like to walk on that. We have 1 wildly enthusiastic pup who loves babies, not the best situation for visiting family so we got a training collar that has warning tone or shock feature. He hates the "tone". We only had to "tone" him 2-3 times (practiced it alone first) and we now don't even need to turn the collar on. We never used the shock feature. We put the collar on him when visitors arrive, he is well mannered and we take it off after the greetings are done. We've always had 3-4 dogs at a time and are not very good at dealing with training all of them at the same time. Seems like they finally get the idea by the time they are 2 or 3 years old but since they are all different ages we've always got at least one young one in the bunch.
