Hello, I have a 15 lb almost 6 month old female lab mix. She has been to the vet three times and has had blood work done where everything looked good but Lately she has been very excitable reactive to our neighbors dogs. I have been watching a lot of videos and reading up on how to help her with this issue, I will also be signing her up for training classes. One thing I am interested in trying is, I have heard that melatonin can help with reactivity issues. Dose anyone know if it is safe for puppies to take? All of the brands that I can find online say for lifestyle dog. Also because after she was spayed she was urinating very often I started giving her chews for spayed female which contain soy and red clover extract could these be making her more reactive? I am worried about these chews also because she seems to have quit a bit of crushing disease symptoms, will these hormone supplements affect her if she dose end up haveing this disease? Also if anyone has any calming puppy supplement ideas I would apprciate it, Thank you so much.
