Is this enough time for the crime?

A 21 year old man, was visiting friends when his 4 month old puppy had an accident in his friends apartment. The man then beat the puppy and put her in a crate, poured bleach on her and set her on fire alive.... he faces up to 4 years in prison.

I want to know do you think that is enough time? I personally think he deserves 10 years. I think the judge should consider how animal abusers can eventually be dangerous to humans!! Why dont some people see this?!!
