I have a 5 year old rat terrier that has out of the blue attacked me 2 times?

Question

My rat terrier has bitten me twice now and I dont understand why. He is normal and loving and all of a sudden he will go crazy. The first time is when I had bought him a baby and he chewed it up and when I went to clean it up he went nuts and bit me. The next time just a couple of days ago I fell asleep on my couch and when I woke up he was humping my leg and I told him to stop and he went crazy again and bit me again.

Answer 1

You have a dominance problem in a big way.  He should have been neutered at 6 months to prevent this.

I know a lot of people are against neutering their dog because they think it's cruel.  It is far less cruel than letting the dog develop the powerful urge to mate, but never let him do so.

Answer 2

make cat food out of him

Answer 3

it might be an injury or his hormones,you might see a vet,and also think about getting him neutered.it sounds like he is being territorial,and neutering might help that....
