Whether they're new to the family, or perhaps just going through a tough time, the Snuggle Puppy is designed to provide comfort and helps relieve anxiety in your four-legged friend. Whatever the case, whether crate training, a new transition, fireworks, or perhaps a thunderstorm, rest assured the Snuggle Puppy will be there to help. Dogs and puppies are pack animals who are instinctively drawn to their mother and others in their pack. The Snuggle Puppy recreates the intimacy and physical warmth and a "real-feel" heartbeat. The result is a calmer, more peaceful pet- one that feels less loneliness, fear, and separation anxiety. The "real-feel" pulsing heartbeat comes with 2 AAA batteries that last up to 2 weeks with continuous 24/7 use. The hearts on/off button allows for use when needed. Included with your Snuggle Puppy is one disposable warmer pack (non-toxic, safe for people and pets, each pack lasts 24 hours) for an extra source of comfort for your pet. The Snuggle Puppy is all natural, medication free, and not a restraint. It calms your pet by appealing to their basic natural instincts. The Snuggle Puppy is machine washable on a gentle cycle (make sure to remove the heartbeat prior to washing)
