Even a hare will insult a dead lion.
I have other fish to fry.
If the lion's skill will not do, we must sew on that of the fox.
Like a fish out of water.
No peacock envies another peacock his tail.
The wolf changes his coat but not his nature.
When one dog barks another will join it.
When the old dog barks it is time to watch.
Who lies with dogs shall rise up with fleas.
