Also, let me ask you a few questions: All our panels have a centre bar, Do other panel makers have this? This takes the impact as the dog jumps against it. All doors can be locked secure when you are inside the kennel, do other kennel makers do this? Why use mesh instead of bars? Well bars bend and with the rising number of dog thefts where people place a scissor jack in between the bars to open them up, in our opinion mesh is the only option for a safe and secure kennel.
