Never have taken Newlie and never will. Some people on this forum do take their dogs to dog parks and say they have done so for years with no problem but my feeling is that everything is always OK until one day, suddenly, it isn't. And sadly, sometimes it only takes one incident for there to be irreparable damage. So, while I hope that things continue to go well for them, I wouldn't count it. To me, it's like playing with a loaded gun, sooner or later somebody is going to get hurt. And bear in mind that whenever there is an altercation, it won't matter if a smaller dog is trying to rip your dog's face off, the big dog will always get the blame and be the one called "dangerous."
