If you want to become fluent in French, you must learn all types of vocabulary including the kind that is not necessarily found in most textbooks, but which you will find on the street as you talk to French-speaking people.  Today, we’ll talk about some popular French terms including slang, idioms, colloquialisms, etc. that are animal-related, but not necessarily in meaning. 

First, just like in English you can say that a man is an animal.  Il est un animal.

Une bête is literally an animal or a beast.  But, it is often used in some form in colloquial French.  For example, as an adjective it means ‘foolish’ or “stupid” as in Elle est vraiment bête (She is really foolish).
Ne fait pas de bêtises!  “Don’t do stupid things!”
(ne pas être) aussi bête qu’on en a l’air è not to be as dumb as one looks
Elles ne sont pas aussi bêtes qu’elles en a l’air  “They aren’t as dumb as they look” 

Now, moving onto specific animals…
Let’s start with ‘duck’ or canard.

Colloquially, un canard can mean a hoax.  For example ‘un canard publicitaire’ means a publicity stunt.
Faire un froid de canard means it is very cold.
Il fait un froid de canard. “It’s very cold.” 

Likewise, temps de chien means “bad weather”
Il fait un temps de chien  “The weather is really bad.” 

Then, there are the expressions with ‘pig’ or cochon.
Un cochon can mean a pig in the same colloquial sense as it is used in English as in somebody who is very messy or says nasty things is un cochon.
Faire un temps de cochon means the weather is really crappy
Il fait un temps de cochon. “The weather is really crappy.” 

There are other expressions with ‘horse’ or cheval.
(être à) cheval sur quelque chose means to be a stickler for something
Je suis à cheval sur l’ordre.  “I’m a stickler for cleanliness.”
(avoir une) fièvre de cheval means to have a high fever
Ma petite fille a une fièvre de cheval.   “My little girl has a very high fever.” 

A “goat” or une chèvre can mean an ugly woman or girl.
A “bird” or un oiseau can mean “a guy”.
A “hen” or une poule can mean ‘darling” as in ma petite poule or “my little sweetheart”.
A “mouse” or une souris can mean “a woman” or “a girl”.
A “zebra” or un zèbre can mean a “guy” or a weirdo” as in un drôle de zèbre. 

Then, there’s the monkey or singe.
On n’apprend pas à un vieux singe à faire la grimace is the same as the American expression “You can’t teach an old dog new tricks” 

There’s the expression with sheep or des moutons - Revenons à nos moutons “Let’s get back to what we were talking about.” 

And finally, there’s the cow or vache.
La vache! means “Wow!”  much like we say in English “Holy cow!”
Vache when used as an adjective can mean “nasty” or “mean”.  For example, Ma copine a été vache envers moi meaning “My girlfriend was mean to me.”
