I bought walker a prong this weekend. A little late for the trip since the stupid neighbor couldnt keep her dog in the yard and not even 3 minutes after i took him out the 10 lb mutt had a death wish. (BTW walker was on leash in a martingale but theres only so much a martingale will help) It is a Titan Collar nice and heavy VERY well made but it didnt come with comfort tips. It DOES have rounded tips and Walker wore it that way all weekend and wasnt phased that it didnt have the tips. So the question is should I buy them or not? I pulled it against my arm and it didnt hurt at all so I dont know.
