hmmm.... that could be correct!  i haven't seen
all of hajime no ippo yet, only about the first
30, so i haven't seen the dog yet that i remember.
 but the seller has lots of hajime no ippo cels
for pretty cheap, so that could very well be where
it's from!  thank you, and when i get some more
episodes, i'll keep an eye out for the dog! ;)
