Generally, teething puppies are so uncomfortable they need something in their mouth at all times. Because they are such busy bodies, it can be tough to watch them at all hours of the day. This is why they may chew furniture, clothes, and even you! As you can imagine, frozen carrots for puppies are great alternatives to all of those. In addition to preventing your puppy from destroying your home, frozen carrots last a long time. When Ezra was a puppy, a frozen carrot would last at least 15-20 minutes. It was a welcome break from my little terror and gave me a chance to focus on other priorities.
