Provide comfort and relieve anxiety for new family members or anxious pets with Smart Pet Love's Snuggle Pup. Dogs are pack members and instinctively go to their mother and their pack for protection and comfort. With a warming pack and battery operated heartbeat, you can provide your dog with a sense of warmth and security to help them sleep through the night, provide comfort during stressful situations and separation anxiety, and help in transitioning to their new home. Disposable non-toxic heat source lasts for 24 hours. Two AAA batteries (included) last up to two weeks with continuous 24/7 use, and the heartbeat has an on/off switch you can use only when needed. Snuggle Pup is machine washable (remove the packs first) on gentle cycle and is a soft, cozy and comforting best friend for your pet.
