We've had our pup for 4 weeks now, he's very hyperactive (as some pups are) and is still very nippy. Mostly at our pants these days.
We play chasey and fetch in the backyard, he gets taken for short walks, he has chew toys which are always nearby.
When he nips he gets negative reactions including a firm deep voice and then being put in timeout in the laundry when he continues. When I physically remove him from my pants he tries to nip at my wrist.
He receives positive reactions including praise and bellyrubs when he's being gentle and licking.
Hoping that people in here will have some advice on other things I can try please
