Hi and welcome! Fezzik is a cute name, and he seems to be doing very well already!
Looking forward to seeing the pics(you don't need to upgrade to post pics.) You just need to upload here (you will find the link to create albums on your profile. To get to your profile, click on your name
), or to another site like flickr. Copy paste the bbcode(s) for your pic(s) in your post.
If you scroll down you will see the section 'The puppy Place" . You can post your questions in the appropriate category. Puppy Behavior for separation anxiety.
Or, here is the link : The Puppy Place - German Shepherd Dog Forums
Enjoy your pup!
