Young dogs can react unpredictably to electric dog fences, so understanding a puppy's development is essential to deciding when to start training the animal with the fence and collar. Generally, puppies should not be introduced to electric dog fences until they're at least four or five months old.
Therefore, the ideal age to commence dog training is from 6-12 weeks. Considering the above-mentioned parameters, it is important that you adopt a puppy not before 6 weeks and not after 12 weeks. If you adopt a puppy after 12 weeks, you are losing the critical socialization period.
