Hi I’m Diane Costello, owner of Blue Devil Pets LLC. I have been petsitting full time since 2019. I have three dogs of my own and a cat who thinks he’s a dog. I’ve also got a human partner and a human child. My hobbies (besides petting all the dogs) include reading, genealogy, hiking, camping, canoeing, geocaching, and collecting tiki. I started putting together this website when I had more free time in March of 2020… It’s a work in progress. I have plans to share pet care tips and news, as well as featuring fun places to take your pet in Marietta, GA.
