HALTI

Hi all. I’m a new user on petcollars forum and I’d like to ask about the advantages of using a halti collar for dogs. I’ve got german shepherd dog at home and I take him out every day. Lately I’ve seen many dogs with this type of dog collar in my neighbourhood and I was wondering of buying one else for my dog. Also I want to ask if it’s available for all dog breeds or specific for certain dog breeds. Thanks
