Just as stop dog barking collar systems can be used on small breeds, they can also be safely used on puppies. However, you should not use a system that delivers static electricity. The skin of puppies is generally thinner than adult dogs so the degree of tissue injury resulting from the application of static is usually greater. Additionally, you don’t want to instill fear into your young pet. Citronella dog collar systems may work, but it is also considered an aversive type of training tool. Your best bark collar for puppies should deliver only the most humane way of correcting the behavior, preferably through sound or vibration or both. Moreover, the right size and weight of the device should be specific to puppies.
