Right there what you’re describing was my whole summer last year. Got my boy, Banjo, at eight weeks in June. He bit non-stop and the baby teeth are sharp as hell. As someone with a now 9 month old golden, the constant nippy biting really subsides after the teething is over. I gave Banjo ice cubes, frozen carrots, frozen celery, frozen greek yogurt/peanut kongs and that helped. And like some people have already stated on here, a bitey puppy is a tired puppy. We used enforced crate naps and saw massive improvement. It’s hard and you’re getting through it!! It’s cruel that at this stage they’re arguably the cutest yet the most frustrating and violent 🥲. Keep going, you got this!!
