I froze them so it would make the dog work a little bit more and he loved it. His breath has gotten a lot better than it was and he really likes them. Helps me out with is dental care since he's not cooperative with brushing.
This is the best product I've found for my Chihuahua's breath and teeth. It really cleans their teeth and the small bites are just right for them. They really like the flavor of these treats. I give them one after meals and one in the evening, 3 per day of the small bites.
Honestly, I only added these to my purchase so I could get the free shipping. I've bought several different dental treats and my Shiba Inu would eat one or two and after that, bury them in the couch or hide them outside. I didn't have high hopes for these because of their strong smell. He ate the first two and then started the same routine, carrying them around in his mouth and whimpering until I took it away. However, I found that if I cut these in thirds, he is fine. He takes each off to eat, then comes back for more and even gives me a look like "can I get more?" I noticed after the second day, his stool was dark green but his system seems to have adjusted and his stools are now fine.
