If you've got an anxious dog or new puppy, this Heartbeat Hippo is an absolute game-changer! The toy features a removable heartbeat simulator that mimics a real mother's heartbeat, providing incredible comfort to stressed or lonely pets. It's perfect for separation anxiety, crate training, rescue dogs adjusting to new homes, or puppies missing their littermates. The ultra-soft plush material is pet-safe with embroidered features (no plastic eyes that could be chewed off), and the whole thing is machine washable - just remove the heartbeat unit first. The Velcro pouch keeps the simulator secure but easy to remove for cleaning or battery changes (requires 2 AAA batteries, not included). The durable stitching holds up to cuddling and gentle chewing. Whether your dog gets nervous during thunderstorms, hates being alone, or is just adjusting to a new environment, this soothing companion makes a noticeable difference. The packaging is eco-friendly too - vacuum-sealed to reduce waste, just fluff it up when it arrives. Seriously, if you want to help your furry friend feel more secure and relaxed, this hippo works wonders!
