Hi my dog is a 2.5 yr old female lab, we adopted her in September last year, since then she was pooping greenish stool which was then resolved. I gave her gizzard with rice and vegetables in meal twice a day. But now again she is pooping very little and the stool is dark in color from outside and yellow from inside. Also she has developed this hairloss patch around her collar area. Is all this related and how to treat it? The regular deworming is recently done.
