Hi all. Next week we will be getting a new puppy (female, just under four months old). The dog is coming from a rescue, and they speculate that she is a collie/german shepherd cross. I've not owned a puppy since becoming an adult. The last dog I got was ~18 months old, and though she still had a lot of puppy in her, I'm sure this time will be significantly different. Does anyone have a particularly favorite book or website on dog training? I want to do a better job with training this time than l did last time. Thank you.
