Dragon in prison

Translation:

Don’t think, don’t think that I’ve paid you in such way for bread
Having run to a new, too successful and impudent flag.
I’m your dog, your devoted and loyal old dog who was chained
By the man who’s afraid of the dogs already since his early years.

I had bitten as I could but my enemy was slier and meaner,
Neither wolf teeth nor wolf blood in my veins could save me at last.
Lots of days I can hear from behind closed doors of my cell
Only guards’ voices and measured evil steps going past.
