<human>: Hey guys, 

I should begin by telling you that my dog (Nearly two now), is scared of a lot of things. No he wasn't brought to my home from a shelter or RSPCA or anything, we got him from a breeder. He is scared of things ranging from a broom, to his own bowl or even a basketball.

In my opinion, he is this scared because of an accident that happened last year. We have a deck out the front and sometimes we would tie Pepper with a leash, onto a coffee table (wasn't very smart). We have done this multi times before, but he suddenly sprinted away (not chasing anything) dragging the coffee table behind him. He was frightened, he wet himself and everything, and it seems, that since then he is scared of everything as mentioned above.

So pet lovers of Reddit, could I do anything to help him not be scared of things?

Can you succinctly summarize the text in 1-3 sentences?
