Don’t chain a dog outside for extended periods. It promotes viciousness, suspicion of what is beyond his reach and susceptibility to being teased or frustrated. It can also be dangerous because the dog may wrap himself in the chain, or even hang himself. Particularly, never allow your dog to wear a choke collar unattended. A roaming Pyr can catch a choke collar on a root or bush and eventually the dog could die of strangulation. A choke collar should be regarded as a training or show collar only.
