puppies

i just got a puppy. her name is lala. one of my favorite images so far was when she came up quietly behind rex, one of my cats (who currently hates her), so that rex didn't know she was there. rex is starting to let her get a little closer but this was pushing it. lala put her little paw out and touched rex's back. rex jumped around and looked at lala for about 3 seconds. lala was so surprised that rex wasn't hissing that she started to jump and bark. at which point rex, clearly thinking "what IS this thing?!" started to hiss. and promptly ran away to go back into the house. why lala thinks the best way to be friends with the cats is to bark at them and try to jump on them i think is just a difference between cats and dogs.
