With some info given to me and careful concideration I think I have determined it is a yeast issue in my pup. After examining and looking at pictures online she now has that spot under her neck, on her feet and wrinkle folds on her face she has yeast. Where do I begin to get rid of this? She is eating fromms puppy. Should I change her food flavor? Also, do I need to replace her treats (which I would hate to do she loves them and i stocked up big on these lol) but whatever is best. her treats are think dog lousiana crawfish jerky. But i have never dealt with this so where do I begin and will it go away in time or immediately? Also what can this cause?
