First of all I would like to say I’m beyond impressed with this product, but for that same reason I wish the two products were a little more leading in which you should order. I ordered the smaller product thinking it was the correct size for my boy Nos, he’s a 100 pound Pit-mastiff. Upon using the product he immediately maxes out the cord, he’s been maxing out the cord for the past couple weeks putting hours into it and it has yet to show any sign of weakness, but I do get anxious hoping it won’t snap and hit him one of these days. So when picking this product a normal pure bred pit or medium sized dog the smaller product will do great but any large to extra large dog spend the cash for the larger one. For the company maybe list some recommended weights or actual dog breeds for which product customers should order for their babies.
