Happy #NationalPuppyDay ! 🐶 Did you know that dogs aren’t the only animals with pups? Other species, like the fox, have young that are also called pups. In the spring, a mother fox gives birth to a litter of 2-12 pups (also called kits). When the pups are about seven months old, they’re ready to strike out on their own. By winter the pup will find a mate and will stay with that mate for the rest of their life.
