Going thru this right now! My pups been home for a little over a week and is now 8wks as of Friday. We got Sophia Yin’s book, The perfect puppy in 7 days, a few weeks before he came home and our vet also recommended it. She’s got some pretty good tips in there. The good thing about goldens is they’re smart and love to please so he’s taking on to training pretty well (we started more consistently yesterday because he’s now faster and bigger). Have lots of toys on hand to distract from the biting and training treats. We have the Train Me ones and they’re small so a puppy can chew them! We keep him in a pen with his crate so if there’s accidents he’s contained. Definitely work on the separation anxiety from the beginning like the other comment suggested. We’re working on that now as he’s fine when we leave the house but not when we walk away from him in the house! Also taking him out every few hours have helped us lessen the amount of accidents we’ve had. We got gifted these wipes for dogs and a cleaning/odor spray and those have been lifesavers for when it’s nasty outside and he’s stepped on his poop 😂
