ANY CLUE????

sounds like a staph infection.

Do you know what I should do until I can take her to the vet??

You don't say where you're located (and honestly knowing what part of the country you're in is a HUGE help) -- but that could be anything from a contact allergy to actual "bites" from something.  And likely whatever caused it originally has turned into some sort of staph infection.  So you **WILL** need to go to the vet and you'll need antibiotics (because infected skin may "change" but it won't HEAL without antibiotics ok?)

 Go to Wal-mart (or most any half-decent pharmacy) and get 2-3 things.

1.  Pan-Oxyl Bar soap 5% (in where the teenager acne/skin stuff is).  If you can't get that, then get Oxy Chill Factor Benzoyl Peroxide wash (read the label -- you want the one with benzoyl peroxide NOT salacylic acid)

2.  ex-foliating gloves (in the bath/body area -- gloves you put on to knock off dead skin in the shower -- again this is human stuff)

3.  Tea tree oil -- in Wal-mart it's usually on the bottom shelf on the aisle where the herbals/vitamins are -- 2 oz bottle with a green-yellow label.

 Bathe the dog in WARM RUNNING WATER (that is soooo important -- cool water will trap the benzoyl peroxide in the skin and make this worse).  Yep, I mean in the bathtub or something where you have a hand-held sprayer and ***warm*** water. 

Rinse a LONG LONG LONG *****LONG**** time.  Don't scrub hard -- the gloves just enable you to work up a good lather with the soap on your hands before you wash the dog -- so the soap will be on your hands, ok??

Then -- after you have rinsed a LONG time (like 5-10 minutes - I really mean a LONG time),  then put just a little tea tree oil (maybe half a capfull) ON the gloves and again massage the dog -- *not hard* -- but just work it all thru the coat.

 RINSE AGAIN.  Don't leave a lot of tea tree oil on the skin -- it will make the dog sick if they ingest a lot of it. 

Because this is mostly on the underside -- it's a darned good possible that it's either a contact allergy or bites from something the dog has lain in. 

You can bathea couple of times between now and Friday.  The tea tree will prevent the skin from getting too dry. 

I've got a prescription medicated, antibiotic shampoo for my dog when he breaks out - is is caused by contact allergies in the grass. We get flare ups every now and then, depending on the season (I think we're about due for one now....) my vet reccomended the shampoo over oral antibiotics.

Sounds like staph to me too, if it looked like bug bites.  My dog had this and needed antibiotics.  My vet told me NOT to wash the dog or apply anything b/c moisture would make it worse and if you are not using the right strength of antibiotic, it will not help.  It depends on the severity.  Many dogs are cured with a special shampoo, but others need a very heavy dose of antibiotics in order to cure it and not have it become resistant to the antibiotics.  If it's not the right treatment it can also irritate the sores even more and flare up.  Her infection covered her belly, chest, and underside near her privates.  She took two Cephlex twice a day for 14 days and it cleared it up.

If it's not the right treatment it can also irritate the sores even more and flare up.

Absolutely.

Lies -- if it is **yeast** that's typical -- because moisture increases yeast -- but being on the nose and chin/lip area it's probably not yeast -- but it is likely to be a contact allergen.

Benzoyl peroxide will also cut the contact allergen so it doesn't continue to burn.

It is *very* typical for a contact allergen to spread to the lips/mouth area -- because the dog licks the areas that are itchy and the contact allergen *spreads* to the mouth area.  That was actually what tipped me off that it's probably a contact allergy.  It will provide a lot of relief to bathe that away so it doesn't continue to burn deeper.

Erica and I live down here in the land of LOTS of contact allergens.  St. Augustine sod, wandering jew, night-blooming jasmine -- they can make a dog pretty miserable.  There are contact allergens all over the country -- sometimes it can be transmitted when a dog goes to a lake or stream where the plant is growing, etc.

Poison ivy is a common human contact allergen -- it's the oils in the plant that cause the problem and spread it.  Poison OAK is far more the problem for dogs (and that one is all over the US I think)

They can be spread by the human walking thru the plant and the oils transfer to the human's shoes or clothing - then the dog lies next to you or even lies on the carpet where you walked and voila -- CONTACT.   So it can recur, not just by contact with the plant but by contact with something else that has had contact with the plant oils.

Thank you.  I've just been sitting here wondering what I need to do, because I can't just sit here and watch her go through this.  Again thank you so much for your response.  I'm running up to the store and hopefully this helps her.
