In Toa's fosterhome with his littermates, one of the pups came back positive for mange....they scraped Toa a couple weeks before we got him because he was going through an "ugly" phase and had lost some hair on his head....he came back negative....

Mom just got back from the vet with Lily and just called me and said that Lily tested positive for mange today.  She said that there were some red "rashy" sports on Lily and the vet could tell right away. 

SO, with the knowledge that two of his littermates have come up positive for mange, should i get him scraped no matter what?

When I took him to the vet yesterday and asked the vet about it, I explained that his hair is looking better since hes been home with us and we changed his food and everything.  She shrugged her shoulders , of course...LOL...and she said to keep an eye on it and if it seems to be getting worse bring him in for a scrape...I asked her what SHE thought and she said the same thing.....part of me wishes she would have just suggested i get it done yesterday "just incase"...

his skins looks fine except for a few tiny marks from Trixi and him wrestling....his hair loss SEEMS to be improving....his hair is looking thicker and healthier....but its also so thick that we cant see his skin very well, which is how my mom coudl tell, by the pink skin on Lilys head and neck....

What do you guys think?

I wouldn't worry about it.  Mix up a little peroxide/borax and sponge it on and see if that helps.  They very well could have sold you a couple hundred dollars worth of mange cure so count yourself lucky.  Granted, they could at least acknowledge your concerns with an explanation, but if I were you I'd save the money and buy some Seapet fish oil instead.  It's probably the best thing you could do, for both your dogs health.

I get the Seapet 200 with/E from their website.  http://www.seapet.com/Oil.htm#omega3E

I would use the peroxide/borax if you notice bald spots.  If it is just thinning, and getting better like you said, I wouldn't bother.

I wouldn't get treatment from the vet.  She's still getting puppy vaccinations isn't she?  That can trigger the demodectic mange.  I would seriously doubt that it's sarcoptic (contagious) mange.  I'd just keep an eye on it and if it spreads, try the peroxide/borax before letting the vet treat it.

My mother's jack russels terriers, all ended up with mange.  My mother even ended up with it .    The dogs received shots and my mother was treated with a topical ointment.  All soft surfaces must be treated in the home.  The mites that burrow under the skin and cause the rash can live in carpets for three to four days.  I researched this stuff big time.  It is nasty, nasty , nasty. My mother was banned from visiting me.  My sister had her dogs and house treated just because she took one of her dogs to my mother's before they knew it was mange.  Mange is nasty, it must be treated early and hard.

Correct, it was sarcoptic mange.  I didnt think that they were sure what they had yet.  It's just that my mom let it get out of control and I wouldnt want anyone else to.

I've dealt with sarcoptic mange with my minpin.  It started as hair thinning around the little wrinkles in his forehead.  He was a very sickly baby and so his immune system couldn't fight it.  Anyway, we(all who held him close) did get it.  We started itching and getting little red bumps.  We had to put this poison lotion all over our bodies...then my dad had a reaction to that...He was so funny...he was a true southerner and had been a farmer as a boy...he said, "I've been around dogs my whole life and never had a problem, but you bring this little sick rat to me and now I've got the mange!!"  He was not my Bruno-boy's biggest fan

Bruno suffered with skin conditions pretty much the rest of his life.  Good luck and I hope that these puppies all get better.
