Agglomerative hierarchical clustering technique

Earlier in the year, my AI lecturer taught us about agglomerative hierarchical clustering and K means clustering but his explanations are lost and i'm trying to figure out how he uses the data in the table below to create a dendogram. It would be great.

enter image description here

He comes up with the following table that outlines the similarities: 

   Animal pairs          Similarities
Bear & Tiger                  4
Bear & Dog                    3
Bear & Giant Squid            2
Bear & Cat                    3
Tiger & Dog                   2
Tiger & Giant Squid           1
Tiger & Cat                   2
Dog & Giant Squid             2
Dog & Cat                     5
Giant Squid & Cat             2

And the resulting dendogram from the table above: enter image description here

Always connect the most similar ones.

Dog and Cat are most similar, and are thus connected at level 5.

Bear and Tiger are connected at level 4.

etc.
