Loyalty is not a negative trait, nor was I using it to defend a breed, merely a statement about the breeds characteristics. If a dog acts aggressively through a stranger approaching then that's on the owner, lack of or poor training in their early years.
As I said, most dogs are fine some aren't, it isn't breed specific. Where I live there's a lot of dog owners with a huge range of different breeds including a couple of bully XLs, the only dogs who've been aggressive over the years are a spaniel that tried to bite everything in it's path when off it's lead. The owner doesn't let it off the lead anymore after she had to stump up for several vets bills and copped a lot of flack off everyone for it. The other is a very aggressive german shepard, it's always on a lead and always muzzled, the owner is a giant too and keeps it under control at all times, it's a rescue dog and really doesn't like other dogs but it's never a problem because the owner keeps on top of it. We pass a lot of dogs each day, some days dozens, from tiny little rats on leads, up to bully xl's and a bloke with a pair of Saint Bernards, a handful that pair are
, no aggression from either side, they either ignore each other, have a bit of a sniff or have a bit of a run round.
If a dog goes "crazy" of course it's on the owner, who else would it be on?
Don't cuddle dogs, especially around the neck, most really don't like it, however they'll tolerate it, but occasionally one wont, don't do it, ever, and that's the problem some owners of dogs and toddlers are ******* morons.
