Hi,
I have a seven year-old Lab with a lovely temperament. Recently sometimes when he is on lead he will growl at other dogs if they approach him. He never snaps or anything and he never does it when he’s off-lead, he just doesn’t seem to like other dogs sniffing him when he’s on lead. This can happened whether the other dog is on-lead or off.
Any advice on training I could do to combat this? I know he’s only saying he wants space but it makes me nervous especially as other owners jump back etc.
