Twin Wolves by Scarlett Grove

Fox shifter River Radcliffe was trapped in a hyena compound until she was rescued a few years ago. After being returned to her grandparents, she finds a new life with her Border Collie Boo. Determined to move on, River signs up to intern at the Wilde Ranch in Colorado.
Wolf twins Cal and Cash Wilde are known as trouble makers. Stuck with babysitting the interns, they almost miss the notification telling them their mate has been found. When there is a strange glitch on the dating app, they have no idea who they’ve been matched with.
When River arrives at the Wilde Ranch and realizes she really has been matched with both twins, she has no idea how to deal her predicament. She wants to reject them both.
But soon the three shifters come to a compromise: River will date both twins until she decides which one she wants.
Will River find a way to let a man into her heart after everything she’s been through? And how will the twins preserve their bond if one of them is left without a mate forever?
