re: My dog has a huge abcess thingy on her neck under the skin

Clip the area clean and clean it with some rubbing alcohol. Heat up the needle and go straight in with it, as you pull out you can use the tip to make the incision larger. As long as its open and draining it will be much more comfortable for your dog. If it isnt a abscess or cyst nothing will come out and then you need to likely have it removed. As for LA 200, about 1 ml per 25 lbs SQ (under skin) is safe to give but wouldnt give multiple doses, just one then get some antibiotics from your vet. Yes I am a vet.
