The Wildfang® chew toy selection is extensive, but which one is the best choice for my dog? The decisive factors here are your dog's or puppy's bite force and their passion for chewing. If your furry friend prefers to chew intensively all day long, you should choose a chew toy with a high chew resistance (++/+++), such as the chewing root made of tree heather, the olive wood or the Coffee wood - optionally with Salmon oil.
