Cocobean is adorable. I wonder if it would be helpful for awhile to not let Cocobean loose with the other dogs until she has time to do lots of sniffing of them and get used to them and vice versa. For example, either keep Cocobean in her pen or the other dog's in their crates. However, have them near so she can sniff them but still feel safe. I don't think I would feel comfortable right now letting them all together. Hopefully others who have big dogs have some advice. I am very careful if my dogs are around big dogs because they could be easily hurt.
