Many MANY dogs are capable of slipping out of a flat collar.
If your dog doesn't need a training collar we always recommend a martingale collar that they cannot slip out of.
There are many different materials that flat collars can be made of nylon, cotton and leather.

Just like all other collars we do not recommend that you just let the dog pull against it.
We also never recommend that any collar is left on any dog unsupervised. In a crate, house, backyard or any other area unsupervised. But PLEASE Microchip your dogs!
