Yes!! I just got Petzlife teeth gel and have been using it for about a week and a half. Toby's teeth already look great!! What a difference.

Peanut's teeth are taking a bit longer to show a difference, but from what I read it can take a month to show a significant difference in some dogs. I use it in the morning and at bedtime. It is soo easy to use, but they do hide from me now when they see me with the bottle. LOL!!
