I imagine it IS!!

I only barely understand making videos!

at all! I am just barely smart enough to be able to
watch a video!!
but, picture IF someone DOES send this video around, in an attempt to help you find humans who will adopt these puppies.....
well, the humans will probably think this is just
someone filming their own cute puppies, and after several minutes (humans today have verrrrry short attention spans

)
they'll click it off, long before your screen at the end, which is explaining these puppies
are up for adoption, and ARE looking for homes.
so since you DO have so many puppies to find homes for,
you *might* want to consider either editting that video, to include some words right in beginning the video, "EACH OF THESE PUPPIES NEEDS ONE GOOD HUMAN TO ADOPT THEM" or some heart tugging words

to make ppl watching understand, these puppies NEED a home,
or if it is not too hard, you might want to consider making a new video geared at getting these puppies adopted.
still, i am in awe of your selfless efforts to help these baby dogs,
and of the film itself,
SO CLEVER! SO SO CLEVER!!!! i think if it were just a film about YOUR own dogs, it'd rock! I love the concept of "an adventure film" about dogs, hilarious idea!! loved it!! BEST OF LUCK!!!
I think using videos IS a great way to help others notice these puppies, i think you are on to something here!!
