I've been meaning to order some of this spray, too.
I think Jackson would fight me to put the gel in his mouth so I'm opting for the spray. Seems so much easier. He will be a year old in a few weeks and I need to get started caring for his teeth better. He's allowed me to brush them 3x in his lifetime
His teeth have NO tarter on them now but I guess Petzlife is a good preventative?
