With Pyrs you need to make sure your fences are excellent condition, tall (7-8') and dig proof. Hot wires around the top and bottom from the start would be best for puppy training.
Starting with a puppy where you can train it yourself is a good idea. Anything much older than 4 months that has not had good starter training has already developed bad habits. A lot of people think by getting an older dog they can avoid bad puppy behavior but that is not true. If the bad puppy behavior was not already stopped with proper training, the oder dog or puppy will be a problem. Better to train the dog yourself from puppyhood. Just be sure you can recognize puppy behavior for what it is and don't punish the wrong puppy behavior.
