why does my hound sometimes when on lead growl & bark at other greyhounds ? Yesterday met 2 greyhounds all on lead warned the owner she may react they sniffed & were all calm & lovely then mine went back and was face to face with the other female and started to snarl I don’t get it ! I’ve changed my lead I have her next to me or behind she was perfect then she did this it’s so random I’ve been told many different reasons & tend to agree with the protection reaction off lead no problems social friendly perfect ,I’m at a loss to figure it out please help
