Is within any agency to retrain a dog after it have attacked a horse? ?

I was riding bareback two weeks ago and one of our German Shepherds got behind my mare and leaped up and ripped a 5 inch piece of store off. The previous day he have nipped her lower on the leg (her hock) but did no real damage an I scold him. But I cannot ride now without him circling me and the horse, barking. I dreadfully had to GIVE my horse away to a rescue group because my mother will not get rid of the dog. But is it true that once they savour fresh blood, they're ruined for life...as far as being safe to own near livestock?
for god sake that dog is dangerous and shouldn't be close any horses let alone anybody else.

i love dogs, i own one myself but if its dangerous its fiesta to put it down rather than let it continue to be a risk to itself and others.
if your dog behaved this way, it be never trained in the first place. This dog obviously has behavior problems and could be a vulnerability out of a controlled environment. Every owner has the responsibility to control their dogs. My guess would be this is dog should not be allowed to be around any animals without a leash or being confined. You should urge your mother to grasp some proper training for this dog before there is a tragic situation. You could have be killed. Doesn't she get that!
Your mother was wrong the dog should have been shot!.It is treacherous.
Yeah Yeah bleeding hearts shut up! about the dog!
I love all animals ,but when they are insecure they should be put down, not "retrained".
i'm not sure but i think that this is a question that will hold more answers in the dog section.

sorry i wouldn't help and that ur horse have to be given away but i hope the advice i gave will minister to.
Answers:    In 1971 I had a Quarter Horse mare who was turned out surrounded by an arena and the owner of the stable used to think it was funny to sic his German Shepherd on her to acquire her to run around.

Well one day while we were coming back from a trail ride, the dog be walking ahead of my mare and I when I noticed my mare speed up her walk. She stepped on Bruce's tail (The GSD), Bruce bit her fetlock, Squaw stuck her nose down and tried to buck me sour!

Moral of the story: Don't sic a dog on a horse, the horse could get even not only with the dog, but near it's rider...

BTW nope, not probable to retrain once they've gotten a taste for livestock. You'd better let your mom know that other property owners do have the right to shoot her dog whether they find it on their property threatening their livestock.
If i breed a solid paint mare breeding?   What do you guess is perfect?   What do you think- dressage smooth?   My connemara pony Rory loves to donate the bizarre buck.?
