Can someone help me out? Bella is around 5 - 6 months... I think she may be in heat because she is very fishy smelling to the point where it makes me sick from the smell she has a weird discharge coming from her V every so often that is milky clear/ yellow fluid that smells horrible and shes always licking herself. My other two dogs I have are fixed and sometimes they smell a little fishy if they lick themselves but never as bad as Bella and they don't have that odd discharge. Does anyone know what it is? Shes a healthy puppy and she has mostly all her shots.
