Reflective Padded Dog Collar with Soft Neoprene - Adjustable Nylon Pet Collar for Small, Medium & Large Dogs - Blue Collar with Leash Included (Pack of 1) - Perfect for Night Walks, Jogging & Outdoor Adventures

I bought 2 sets of collars and leashes for my 2 pitbulls. I bought the light blue for my dark gray girl pup, and black for my red boy pup. They are still puppies at 5 and 6 months old. Their necks are about 15" and 16", and the medium size was easily adjusted to fit with some room to grow. The collars are well padded and I'm confident they are very comfortable. I can see the reflective thread even inside in low light. The closures on the collars snapped in easily and securely. I haven't tried the quick release but I appreciate that they have that feature. I think these will last a long time. I really only needed collars since they outgrew the ones they had as tiny puppies. The leashes are an added bonus. The set was actually less expensive than just purchasing the collars I would have otherwise picked. The leashes are very nice with well padded handles, thick, sturdy rope with reflective threading, and heavy hooks on the ends. I will be able to toss out several worn out thinner leashes from their days as little puppies. So, all in all, these are good quality collars and leashes, and I would recommend this bargain deal. They are easily worth 3x the price I paid for them.
