Dogs need toys to provide mental stimulation, allow for appropriate chewing, and serve as important tools in behavior modification.
Toys are mentally and physically stimulating and assist in fulfilling a dog’s emotional and physical needs.
Even though dogs today are primarily bred as companion pets, they still need something to do. In the absence of toys, they will look for things to do to occupy their time and fulfill their chewing needs.
If you don’t want them to choose their own chew toys, such as your sofa, pillows, or toilet paper rolls, provide them with appropriate toys instead!
