My days are in the summer
When you'll eat me when I'm hot
In fact I'll even eat myself
Where battles tough are fought
But when you find me in a fight
'Twill be high in the sky
And if you catch me napping
I suggest you let me lie
When you're bad come to my house
From Ma get thoughts profound
Am I big or am I small ??
Some say I'm just a pound
Solution: It is man's best friend
Answer: Dog. Dog days, hot dog, dog pound, dog fight.
