My dog wouldn’t stop biting on the toddlers plastic dinosaur toys, so I got him this because it’s similar to plastic. But not hard enough to where it could damage his gums, also not soft enough to break apart. It’s perfect and he’s very happy with it. My dog is 6 LB toy poodle for reference, I would say this is suitable for small dogs. I saw reviews saying that their dog absolutely destroyed it immediately, but then in the review pictures their dogs were baby bulldogs/german shepards! This isn’t meant for breeds like that, but if you have a smaller dog with smaller teeth then this is ideal.

Is this safe for my dog if she chews off little pieces.

Size: Small/Medium, Color: yellow

My Chihuahua loves this, however I want to know is it safe for my dog to swallow? She chews on it and gets little pieces of it and swallows them.
