Puppies can be very destructive. They need a lot of love and attention. Chew toys are necessary so that they don’t chew unwanted objects (like your shoes) and so that it keeps the dog mentally stimulated.
My friend Piper is a very hyperactive Jack Russell Shortie. She has to be constantly doing something, which usually involves running around, playing, or sleeping. She has several toys that she gets throughout the day to keep her entertained. Kong toys are her favorite because they dispense treats in addition to being fun.
