Search Challenge (5/4/16): Which animals are associated with what professions?

It's time for a bit of fun... 

... and, in truth, a Challenge that's both easy... and pretty hard.  

Here's the key idea for this week.  

As you know, some animals seems to be closely linked to certain professions.  For example, the dalmatian dog is often thought of in connection with firefighters (at least in the US).  If you see a dalmatian dog (the white dog with black spots below), you think of a firefighter. 

There's an interesting reason why that's so, but I'll leave that to you to find out.  

But thinking about this larger question--HOW would you find something that's difficult to express as a search?  

The key of this week's Challenge is to see if we can find a general strategy to discover which animals are linked to particular jobs.  

Here's how I'm going to put this week's Challenge: 

Can you find an animal that's closely linked to a particular profession?  What's the animal?  What's the profession?  And what's the connection? 

I can think of a couple of professions and animal connections (and maybe you can too).  I suspect the more difficult problem here is to come up with a search query that will work to identify such things.  Bear in mind we're looking for a common relationship between an animal and the profession.  

And no, we don't want things like cow / farmer, or snake / snake milker--those are animals that are basically farm animals.  What we're looking for is something like the dog / firefighter relationship--an animal that is a symbol of the profession.

This is easy, in the sense that you probably know a couple of these already... you just have to say what they are. 

But it's hard in that I don't know how to express a query that will find such relationships.  

Can you?  

Be sure to say HOW you found your animal / profession pair.  And if you can, let us know why that animal is linked to that profession.

Search on!
