One of my Dobes was Schuzthund trained.
He was THE most dependable, obedient and stable dog I've ever owned.
The most "dangerous" dog I've ever owned is this little psycho:
A Portuguese Podengo, she, too, is a rescue and Lord only knows what her life was like in CA.
[someone is breeding them and dumping the "unwanteds" to fend for themselves in the high deserts of California. Most end up as coyote snacks.]
She is dog aggressive *big time* with 2 of my Ibizans.
[who are all 4 times her size]
We have been working on the "pack leader" issue but she got much worse after going into heat her first time.
Ordinarily, she would have been spayed LONG before that happened but we had to nurse her through near-fatal double pneumonia before she was healthy enough for surgery
And as luck would have it, just as she was scheduled to be spayed, *bip*, here came the heat.
For all that she goes "Cujo" occasionally, she loves people, especially little girls. She goes totally submissive, huggy/kissy/giggly with them.
We're assuming that being put in runs with larger dogs at the shelter gave her the crummy attitude about "big dogs".
My 2 smaller Ibizans are her best buddies.
