Title: didn't work for us
Review: Bought this for my 70-pound Irish Wolfhound mix. Fortunately, I tried the collar around the house first. Literally ten seconds after putting it on him, my dog had managed to get it in his mouth and he chewed it in three places. It didn't stand up to being in his mouth for this very short period of time. Tried walking him around anyway just to try it out. Didn't keep him from pulling at all. The whole collar just shifted to one side. Now I don't know if I can get a refund due to the chew marks.
Is the review positive or negative?
