I just yesterday adopted an 8 week old german shepherd puppy. I’m just looking for advice on the best ways to train and even just generally take care of him the best. For example, I know it’s a new environment but I was up almost all night with him last night, is there a way I can make him more comfortable? He came with a toy the original owners had but that did not seem to soothe him any. Just over 24 hours and I am feeling overwhelmed, any advice is welcome!
