The head shaking is the best indication that your dog has an ear infectin, this is especially common in dogs with floppy ears.
Take him to your vet, you will probably get some oticort drops that you will need to put in and massage into his ears twice daily.
You need to do it right away as his hearing can be permanantly affected if it goes too long.
The "brown stuff" you are talking about is more like a dark green look but, it is plankton and is perfectly fine to eat.
Brown, their insides are the same and they eat the same stuff as normal lions.
My 7 week old kitten was displaying the same symptoms and also had brown crusty discharge around her nose. When I brought her to the vet they found out that she had a respiratory infection. She was given some antibiotics and it cleared up in about a week and a half. I would take her to the vet. The worst that could happen is that you'll find out you have a healthy kitty. Better safe than sorry.
your puppy should be three months when you take it to puppy school, at puppy school they learn simple skills like socialization skills an sit, heel etc. Though at six months your puppy can start training for shows. The general answer is at home you can start working with your puppy at about three months.
Eek! It miht be dying. Take her to the doctor. I feel very sorry for you.
