ajdude, I forgot to say welcome! [sm=welcome2.gif]
ajdude:I put a Hartz collar on him, but I heard that these are poisonous. Is this true?
All pesticides are toxic. There are just relative degrees of risk. However, I wouldn't trust anything made by Hartz or most of the other pet store stuff. Going with Frontline Plus is a good move.
ajdude:I also washed him with Dog shampoo for fleas, but I still see a few fleas on him here and there. Is it supposed to kill them instantly?
If a flea shampoo is going to kill a flea, it will probably do so right away. I wouldn't give him another bath in it, however, since the shampoo contains pesticides, too. I suggested you get some original formula Dawn dishwashing liquid. Lather your dog up and let the lather sit for 5-10 minutes to suffocate the fleas. Comb the fleas out of the coat and then rinse very thoroughly. Pour a bit of bleach or vinegar down the drain when you are finished in case any of the fleas are just stunned. Alternatively, one can give a dog a capsule of Capstar as a one time treatment to kill all adult fleas for 24 hours. It is about $3.00 a tablet and is not intended to used all the time. Vacuum the house very thoroughly to pick up as many flea eggs as possible.
ajdude:His belly is kind of red too...I am sorry for all of these questions, but I am just very concerned for my little dog.
Ask all the questions you need to. We are happy to help.
His belly is probably just red from scratching. If any sores develop, let us know and we can give suggestions on that, too.
