Hi my pet is Labrador 1.6 year old suffering in hair fall problem and skin infection by itching so what should I do or what medicine should I give

Hi Gourab. Hair fall, itching and skin infection need an attention as it could be a bacterial/fungal/ectoparasitic/allergic cause. The treatment varies wrt type of infection present. Hence, it has to be clinically evaluated by a vet for the correct treatment. You can either take an online or home consultation on kuddle for the same.
