I have 2 dogs, and let's face it, dogs like to sniff, taste things that they should not even sniff or taste, but there it is, they all do it, period! My dogs don't have killer breaths but they do have bad breaths every now and then, especially my male dog. He has a very sensitive stomach so his breath can vary from normal to bad due to that.
These Minties Vet Grade Dental Dog Treats helps against that a lot. I give both my dogs these treats several times per week to keep their teeth healthy. The treat is pretty hard and firm for them to chew and by being that way, the treat is working like a tooth brush. My dogs love these treats and their taste, and I really like how fresh it makes their mouths smell, it is just like I would have brushed their teeth's and yet, it is the treat doing all the hard work.
A bag or a box of these treats is made in the US which is a huge plus for me. They do not contain any soy or corn products which is also nice to know.
They are pretty expensive, but hey, dogs need to freshen up too sometimes so it is worth it believe me!
