Elephantitis

Both Boots and Tilly have a new affliction. It's called Elephantitis.

The two symptoms of Elephantitis are as follows:

1. They never forget, just like Elephants, Tilly never forgets when she was attacked by other dogs, so she's still reactive, and Boots never forgets where the speakers (the dogs that bark at him) live, he always has to pull on the leash to those houses
2. They're both becoming little fatty's, just like Elephants
