I have switched to the Freshpet diet for my two Chihuahuas and have seen unbelievable changes in their BREATH!! They both have had a problems with horrid breath after eating their previous diet, and problems with plaque buildup. Now with Freshpet, they have had a complete change in the breath problem THANK goodness!! It cost me a fortune in trying to find breath solutions, but it was as simple as changing their diet! I LOVE what Freshpet has done for my girls.
