even your home pack can have issues sometimes. i found this information very helpful as i just added another rescue to my pack and he’s a 100 lb 10 mos. old german shepherd. he seems to be trying to jockey for position in the order of things and is doing some of the things mentioned in this article. it was nice to find out that it’s normal for his age, and that stopping him the way i have been is correct. i hope you will find it helpful, too.
