Welcome, Charlie is beautiful! As for treats, any low cab treat will do. Some of us use bits of cooked chicken, just be sure there are no spices or onions on it, others use Pure Bites which can be purchased at most pet food stores. There are other options as well, just find one that's all meat, no fillers. Come to the main health forum and tell us more about Charlie. What kind and how much insulin is she on, any other health problems and if you're having trouble testing her glucose, we can help with that too!
