2 Pack Safe and Durable Intelligence Dog Toys. These dog toys are made of high-quality plush fabric. The knotted dog toys are made of 100% natural cotton material, which is stronger and more durable. These are the perfect dog toys to train your dog's sense of smell and keep your dog busy. The chew toys are an excellent chew toy for teeth cleaning, contributing to healthy teeth and gums. Improved intelligence toys for dogs: Cute snail-shaped design. Place the treats in the 3 pockets, roll them up, and fasten the Velcro fastener. The snail shape entices your dog to get treats through sniffing and movement, thus training their foraging and puzzle-solving skills. It's also a slow feeder, making mealtimes more entertaining. Squeaky Dog Toy: By loosening the Velcro fastener, the dog toy becomes a long strip with 3 built-in round squeakers that emit a loud sound when the dog chews. Every dog loves squeakers. They stimulate them and help them relax, effectively reducing anxiety and boredom. Interactive Dog Toy: This is an interactive training toy for dogs. When you're busy with work, the dog toy can interact well with your pet, eliminating boredom and preventing destructive behavior. Note: The intelligence toy for dogs is not indestructible. Please supervise your dog's use of the dog toy. Easy to Clean and Transport: The dog toy for puppies can be hand-washed or machine-washed; rolled into a snail shape for easy portability and can be used both indoors and outdoors. This dog toy set is a combination of a sniffing mat and a knotted dog toy and is a great gift for birthdays, Christmas, Easter, and holiday dogs.
