Dogs looking for homes and sitting in the shelter day after day with no one showing interest in adopting them are the ones I find most heartbreaking. Noone to love them and nowhere to go. Ones whose owners, after getting all they can out of them, dump them at the shelter, where they face the possibility of euthanasia.
I get so pumped going to my local shelter to photograph as many animals as I can, to help promote them and finally get them into homes! Or photographing that long timer who a rescue has had FOREVER but seems to get no attention from possible homes. The magic of great photos of that animal sometimes turns his/her luck around. People notice these animals and somehow feel more connected, and adopt!
