Could you please help us with I guess this fungal type but it’s just beginning, he always licks this paw and now it’s bit turned greyish

Hi Likitha. It isn’t much appreciable in the video. I recommend you to get him clinically checked from a vet by booking a home consultation on kuddle. Meanwhile apply ointment Kiskin, thrice a day for a 10 days and discourage licking or biting as it leads to secondary bacterial infection or worsens the condition.
