Responsible Pet Guardianship
Over-population of pets is the #1 killer of pets
5.8 million
dogs and cats entered U.S. shelters and rescues in 2025
597,000
shelter animals were euthanized in 2025
59%
of shelter intakes in 2025 were strays

Every one of those numbers was once a single puppy or kitten, born to a pet whose family meant well but never got around to having them fixed. One unplanned litter becomes two, and soon there are more loving animals than there are homes waiting for them. Many end up on the streets or in crowded shelters, through no fault of their own. Fixing the growing problem of overpopulation starts at home, with one simple decision that spares future litters a hard life.

Impact Story
Kiara’s Story
Kiara is one of the millions of pets that end up in shelters each year. She was scheduled to be euthanized in July 2015 with no hope for adoption until her rescue by HEART.
Her story now has a happy ending, or rather a wonderful new beginning! She has excelled beyond our expectations in agility and search & rescue courses.
Kiara is truly an amazing dog with a beautiful soul who lives to play and whose primary goal is to serve and please, which is exactly what she does 24/7.
