Has anyone had success with a dog trainer helping their dog not freak out when they see squirrels/bunnies?

It was manageable when I just had one, but now that I’ve added a puppy to the mix, and she’s picking up big brother’s behavior (as I knew she would 😅), I need some help training them to stay calm. 😅 Trainers are so expensive though, and I’m hoping to avoid spending money on people who can’t help.

Thank you for any recommendations!
