oh, i hate when they do that! Fido once got out of his collar (i dont use much harness, he pulls so much of it but i use it if i go for a long walk or a walk with other dogs ).
Now i always use a half-check collar (nylon collar, a bit of it chain so he cant get out of it when he pulls back!), i know its not the best for his neck but i use it for his safety, he doesnt pull much with a collar so its ok, i just never pull the leash when he pulls back, i just stop then instead.)
