I heard dogs can learn over 120 words and what those words refer to by the association we gave to them.

We had a dog for several months with two cats, and it saw me hiss at the cats when they were doing something they shouldn't. It realized that when I hissed the cats were doing something wrong. As soon as I would make a hissing sound to check him out with it, he took off barking and barking and looking for the cats!

We had to give the dog away, and we didn't see him again for about a year. The new owner brought him home and I did the test. I hissed. And immediately he remembered the hiss was for the cats when they were in trouble, and barked and barked and looked for them as he always did before.
