Brooklyn's service dog!

Our daughter Brooklyn is 7 years old.  She has been diagnosed with DMDD,  anxiety,  sensory processing disorder,  and speech articulation disorder.  We are asking for help to get her a service dog.  We have to get it as a puppy in order for it to be able to know her and learn her behaviors. The dog will be taught behaviors to help her. This dog will go every where with her to comfort her when she needs it. Thank you so much for helping.
