Ethos, Pathos, Logos

Ethos: " Most shelters examine and give vaccinations to animals when they arrive, and many spay or neuter them before being adopted."

"In addition to medical care, more and more shelters also screen animals for specific temperaments and behaviors to make sure each family finds the right pet for its lifestyle."

"It is a common misconception that animals end up in shelters or with rescue groups because they've been abused or done something "wrong." In fact, most animals are given to shelters or rescue groups because of "people reasons," not because of anything they've done"

Pathos: "Because there is limited space at shelters, staff members sometimes need to make very hard decisions to euthanize animals who haven't been adopted."

"By adopting from a private humane society or animal shelter, rescue group, or the local animal-control agency, you'll help save the lives of two animals."

"Pets have a way of putting a smile on your face and a spring in your step"

"Not only do animals give you unconditional love, but they have been shown to be psychologically, emotionally, and physically beneficial"

Logos: "Around 2.7 million adoptable dogs and cats are euthanized each year in the United States simply because too many people give up their pets, and too few people adopt from shelters"
