(See above for baby Silas picture. Couldn't figure out how to edit and add it here after I posted.)
Ugh, sorry for delay, been one danged thing after another healthwise! Anyway, I'll try to answer some questions (and thanks again everyone for weighing in):
1. The bite was not "horrible," did not need stitches but did break the skin. He only bit that one nightmare of a "trainer," and lunged at vet tech but did not make contact.
2. Yes, he spends WAY TOO MUCH TIME alone and with little exercise other than playing fetch with me in his fenced in area of yard off the porch. I own that 100% - my fault. I am afraid to take him out, which of course, he may sense. In public, I have to be 100% vigilant for people (obviously), dogs (he freaks out) cars (he lunges at them). It's no picnic and I can only barely control him. I am also - embarrassed to admit but we're talking about his life not my stupid pride - afraid of him when he's in his "wild" modes. In the past, he had lept and snapped at my clothing when out, but this was a good year and a half ago when he was still a puppy. My first Shep did this also but outgrew it. Could be he has too but I don't know. I am also afraid of him when (see .3)
3. Overall, he is good with me and my son. No aggression EXCEPT possibly when I leave the house. He flips out. Begins with him staring at and barking at my purse (which I pick up when I leave, obviously he associates me leaving with the purse.) From there he jumps, spins and circles while barking wildly. When I walk to the door, USUALLY he runs ahead and jumps into a window seat in the living room to watch me leave. He stops barking the second I am out of his sight. I say "USUALLY" because in the past 2 weeks he has jumped and snapped at me when I leave. No contact. Yet.
4. He has appt at vet on Oct 30. Going to discontinue the Prozac, hopefully get him his rabies shot and heartworm bloodtest. He will be muzzled. We will see how this goes.
5. Ideally, I would just like to see him re-homed to someone who will appreciate his "special needs" and work with him. And love him. He can be so sweet sometimes and just loves his toys and will play fetch all day long. I too am a horse person - in the horse world, we have a phrase "out horsed" when someone is riding a horse too much/strong for them. With Silas, I am "out dogged." He is too much for me and deserves so much better. Thanks again.
EDIT: found the post I wrote about him at 7 months with vet, if anyone is interested: https://www.germanshepherds.com/foru...ml#post8679466
