The American Society for the Prevention of Cruelty to Animals is well known for its tireless work as a champion of animal rights, and this year they are celebrating 150 years of leading the fight against the mistreatment of animals.
They've shared some incredible photographs taken throughout the years as a way to commemorate their century and a half's worth of service, started in 1866 by American Diplomat Henry Bergh after an encounter in which he defended a horse being brutally beaten by a carriage driver.
Since then, the ASPCA has been a leader in advocating for the voiceless and educating the public on the importance of protecting animals from neglect and abuse. Here are some of their most stunning photos featuring dogs.
