To tie or not to tie?

I waiver back and forth on the pros and cons of keeping Pedrito tied up.  Today he gave me more arguments to keep him tied.

I feed him before I feed Tammy or Oscar to avoid fights.  This morning he thumbed his nose at the food I placed before him.

I saw Oscar laying down in the front yard so I went to feed him.  In no time flat Pedrito came running and tried to eat his food...the same food I had given him.  Of course, it ended up in a dog fight. Tammy came out of nowhere to get between them.

I threw water at them but quickly came inside.  I have enough drama in my life to add dog fights to the equation.
