Review on Country Brook Design Martingale Heavyduty Dogs good in Training & Behavior Aids by Amanda Harrell

I have 2 English Bull Terriers (both rescued dogs). They love to pull each other's collars (!). However, your Country Brook collars are just as strong and sturdy as the day I got them. only replaced this one because it has faded a bit after 3+ years of heavy use (and my dogs are spoiled). So I bought him a new one (I think they sent me a large instead of a medium - or they make them larger than before because this side-by-side "medium" is much larger than the previous one. But too many problems send you return it for a replacement but they are GREAT, strong, beautiful and safe collars!)
