I have 2 chihuahuas that love to come with me on trips in the car and on walks everyday. I need a harness that is comfortable, step-in style (or a style that goes on easily and doesn't have to go over the head), durable, escape proof, not bulky, and can work as my everything harness. I also have other dogs (Golden Retriever and Rottweiler) so I'd like it to be a line that can fit everyone well. The pups and I hate having to do multiple harness switches during the day, and as it's time to get new harnesses anyways, I figured one for all uses is needed. Any suggestions?
