don't panic. We tested him pretty heartily up against some pretty snarling beasts and he was more than willing to leave it. What she actually said was "this pup needed socialization around other dogs so I dropped him off at a doggy day care where someone could watch him". She goes on to tell us we are out of our minds, and if we knew half of what she, and the "trainers"' who said to kill him, we would know that death was the right answer... She knew enough to recognize needing socialization, but promptly set him up to fail by placing him in a completely overstimulating environment. I'm sorry, but asking anyone else to do her work was wrong. Needing socialization means, to me, exposing doggy to the offending stimulous slowly and only to the degree that doggy can handle without a negative reaction.
For Dino, he may well be a total opportunist so adopter should be wilier than that cute puppy. Just a small dose of "anticipation" and his adopter will be just fine.
Lastly, I have heard of a week in Quarantine building curing certain ills. Once I had a foster litter belonging to the shelter and a nasty little beast shot himself straight into Q because of his behavior while with me (myself I would have off'd him) . He sat back there a week and was then re-evaluated where no one could illcit any similar reaction. You might think he was just shut down, but a year after the shelter placed him, they followed up and he remained a delightful and reasonable pup. weird, i know.
It's possible that Dino was hell on wheels, but his isolation, stress and rescue and the passage of time and landing in a qualified foster spot means he has put together the necessary skills to not behave like anass. Many thanks for helping him walk, rather than be rolled out of there. After you left with him, the clerks and I did a happy dance in your, and Dino's honor.
