My son's dog needs to be getting rid of soon.
What is the reason behind wanting to get rid of the dog?
The dog had bitten me several times and it is very annoying
Perhaps the dog just needs additional training. It's wrong to get rid of a child's pet. They will resent you for it.
My dog can't help itself in my opinion. I am the owner and I want to kill it.
You shouldn't kill your pet, how about you hire a trainer instead? Sometimes your pets will act out, but killing them would solve anything and make people think you're crazy.
