There’s also less mystery involved in adopting an adult pet, as it already has a personality and fixed appearance—you won’t, for example, end up with a dog that grows to twice the size you expected it to. November is National Adopt a Senior Pet Month—and to celebrate, pet food brand Stella & Chewy’s will help cover the cost of the adoption. Basically, after you’re finished the adoption process, you fill out a form that includes uploading proof of adoption and a receipt for the adoption fee.
