The Short Answer: No, dogs should not use human toothpaste.
Human toothpaste often contains ingredients like fluoride, which can be toxic to dogs if ingested. Dogs can't spit out toothpaste like humans, so they may swallow it during brushing.
Human toothpaste is typically flavored to make it more palatable for us. Dogs may find these flavors unappealing or even harmful.
Dogs have different dental needs than humans. They are prone to plaque and tartar buildup, which can lead to dental problems.
Opt for toothpaste specifically designed for dogs. Dog toothpaste is available in various flavors (often more appealing to dogs) and lacks harmful ingredients. It's also safe to swallow.
