We rescued a 3 month old pit-bull puppy that had been abused. The poor pup quaked around people and was very skittish. After working with the dog for months, she got better, but it was not until she started the Happy Dogs CBD Treats that the final piece fell into place. Cheyenne is very outgoing and anxiety free the majority of the time. It only took 7 days for us to see her stress all but gone. She can be left alone now without major separation anxiety.
