I have the small one for Loki. It says 3 minutes a day so I just set the timer and give it to him in his crate like I would a Kong. I do have to help him get the front teeth - he likes to chew with the back. He'll chew on a regular toothbrush himself too but this is safer. I called the company and asked them to consider making a smaller one too. The length is fine but it is too wide. It still works, but Loki has to open up REALLY wide to chew it. It's like 2 inches thick. I still like it, but if you have a Yorkie with a tiny mouth it might be too big. |
