Can my pet chew these? Synthetic materials could potentially not be the best bet for your pet, so it is important to choose products that do not have an adverse effect on your pet. SunGrow’s Gaby the Giraffe, Daisy the Dog, and Teddy Bear chews are made with cotton and edible dyes are used to create the color. These soft, durable dog cotton ropes are washable, and reliable to chew on. What breeds/sizes of dogs are these appropriate for? At a practical size of approximately 10” x 6” (27cm x 15cm), and 5 x 4.5” these three cotton rope chews are appropriate for all sizes and breeds. Even the smallest dogs can easily carry these around in their mouths. Even cats will love to snuggle and cuddle with these soft cotton twisted ropes. How long will these last? The lifespan of Gaby the Giraffe, Teddy Bear and Daisy the Dog depends upon many factors such as how often it is used, what breeds it is, how active the pet is and in what types of ambiance. This trio of durable handwoven cotton rope chews is excellent for strong chewers; however, they could fray and rip if very aggressive dogs get a hold of them. If taken care of, your dog’s new friends will provide him with years of entertainment and companionship.
