they did get help from a behaviourist, the problem with giving dogs like this a time to adjust, they just keep repeating the same behaviour, and as pointed out in previous post a muzzled greyhound can't bite, but can still inflict much pain and suffering on a smaller animal, is this acceptable ? not in my world it isn't.

Of course they thought there may be problems, which is why it was on lead, in hindsight (that wonderful science) maybe he should have been muzzled, but it could just have easily happened in their garden, were he wouldn't have been.

The people have also continued to work hard with this dog, they still attend fun agility classes with him now.

We all talk about quick fixes as if they are wrong, but remember it is also a quick fix for a dog, it can get on with the rest of its life, and enjoy it.

If i had something wrong with me either mentally or physically, and my options were sort it now, it may hurt but tomorrow you will be okay, or we can muck about for a couple of years, you can live in misery and at the end of it you may be a bit better than you are now, I know which i'd choose, get on with it and get on with the rest of my life.

I too find the photos of the dog you posted upsetting, but it must have been a old type electric collar, where the charge went into the neck and earthed through the paws. The modern collars give an electrical impulse as opposed to a shock, it does not earth. i have tried one on me, I couldn't feel anything until it got to 25, at 45 it was about equivilent to setting 3 on my tens machine.
