Both of my dogs SBT's have been attacked,bitten and jumped all over by other dogs.My dog was bitten 3 times on one walk as a 5 month old pup
Thankfully he has never retaliated,however my bitch has.

She can be quite aggressive with other dogs and has bitten a dobe and a JR in the last six months

Both were loose dogs who charged at her, and niether owner could recall their dogs,both owners had an ear bashing from my O/H.
Some people love SBT's and some hate them or believe the media hype that surrounds them.
I take plenty of no notice,if they want a chat fine I'll talk Staffords all day long If they want to avoid us fine.I actually find it quite amusing that the media has such an impact,yet if you were to ask them they would swear that it doesn't have any impact on them
