My Bella is a puller too. She is only 35 lbs. but could pull me down the street with no problem at all. The obedience school where we took our last two dogs emphasized the choker collars and they worked very well for them. Bella is another story. She pulls and gags and coughs and seems to not mind that she is cutting off her air supply. She is like Cincy because she walks just fine in the yard. Walking around the neighborhood is quite a challenge. I'm sorry that the Halti didn't work for you. I bought one about 2 weeks ago and found that it turned her into a completely different dog. Before we even reached the end of my driveway she had the idea. She really put up a fight putting it on though. I do hope that you can find something that will work because it is so frustrating to want to spend time walking with your dog and it winds up being not so enjoyable after all. Maybe Carrie or Dixie have some thoughts...
