I see grey hairs on my toy poodle She is 6 months old. Is this some kind of deficiency that needs to be taken care ? Let me know if food needs to be changed or any supplements to be given ? As of now, she is on Royal canine and home cooked meals ( dal , rice and veggies) Occassionally she eats watermelon, cucumber and carrots. - she is not on any supplements - groomer informed that her skin is dry . Kindly suggest what supplements to be given for this condition Thank you
