Had a gyp that was like that, would jump on a another gyp if she came close enough. A guy who bought her put her n another gyp with the same issue, in a dog box together. When they went to fighten, hit took cattle prods n lit both their a$$es up till they didnt hav any fight left in them. Took a couple doses but fixed the issue in less than a wk
How do fix a dog that has this issue and is smart enough to know that your standing there with cattle prod in hand?
use a remote cattle prod........AKA shock collar would be my first choice
