Try providing him chew toys or puzzle treat toys whenever he is biting to divert his mind. Along with his daily walking setting a playing time with him is quite helpful as it will help in letting their energy out which they have a lot at this age.
Cutie 😍 mine also bite so much , after giving him so many toys, still he bites me and almost all corner walls of the house are eaten by him !! He is 3 and half months old , not sure when he ll stop biting 🤷♀️
