I'm running in the morning already half a year, all anything, but there are small and very mean doggies who too run in the mornings. And big are completely not mean, I don't know, probably, it is so only in my park, but they conduct themselves nobler. Small are ran for you as shrimps and anybody and anything can't to stop them: neither the owner, nor a stone, even... I has understood only now, why my wife has refused to run with me. Yes, of course, she isn't in time for me, but it is not a main reason. The reason number one - she has admitted recently to me - "I'm afraid of these spiteful dwarfs. They are sit also in an ambush, and when running past, they are jumping out and barking to a stupor. Their eyelids are gone even".
