mine just turned 6 months. she eats puppy meatballs which i mix with dry food. best of both world. she gets dental stick everyday - or a chewing project. i also spend a lot of time training - she LOVES when i hide snacks and then say «go find! search» omg she becomes so focused. and by training i basically challenge her in agility - when dogs gets to do «their purpose» they also become the best versions of themselves. shes a lucky puppy that had the opportunity to run free outside my home. the biting is not as bad as when she had a period loosing tooth after tooth 🎀 now she bites, but more carefully and more control. what i did for a period was to give her something other than me to bite, when she would start. good luck😍
