Hello all poodle lovers , just a few question.

My dog Jeremy is 3 months old now , how much should I feed him. 2 spoons per meal and 2 meals a day?

I find out Jeremy is being aggressive recently he will start to run around and bite people is this normal as its teeth is growing? Will this habit stop?

Jeremy don't like to wear dog collar, but from what I heard is a must to put it on dogs so that they will kept '' under-controlled'', so should I forcibly put on them?

And Jeremy is a very intuitive dog , it knows a few commands like Sit, Jump and Come. Is very basic, but im opting to teach him harder trick, so is this possible?

thx
