So, I have yet to get Mikey a decent collar. Yesterday on his walk, we had to walk in the street(sidewalks aren't shoveled) and I was scared the whole time because he DOES chase cars and he has gotten out of his collar before. We have tightened it since and I am nearly 100% positive he cannot get off. I know Martingale collars are for Greyhounds and the like but would one be suitable for him? Everytime I've looked, I just see articles about Greys and martingales.

Would it look weird on him? Would it even work on him to keep him safe and ON the lead?
