Liking borrowers is easy! Once you've made a search, you'll see a small heart button in the top left corner of each borrower. To like the borrower, simply click the little heart symbol. The symbol will then turn pink as a sign that the borrower has been added to your likes.
You can also like a dog on their full profile. Click the little heart on the right-hand side, and wait for it to turn pink to confirm that the dog has been added to your likes.
Whether you're a Premium or Basic member, borrowers receive a notification of your interest, and many borrowers will only reach out to owners who they know want their help.
