Petzlife is very expensive BUT it does work.. however with layla i don't use that every day.. just once in a while i put it on a q-tip and rub it on her 4 back molars. I try for every other day brushing her teeth with the toothpaste they sell at pet smart
however don't buy the toothbrush that comes with it... it is too big for our babies little mouths... i went and bought a toddler toothbrush
