The first time I bought the Pedigree BreathBusters, I was hoping for a little improvement in my dogs' breath. I didn't really notice much change in their breath, but I still buy them for a couple reasons. First, the dogs love them! I have a 9 pound corgi/chihuahua mix & a 55 pound husky mix. Both dogs are at least 9 years old. These treats are very easy for my smaller dog to chew & she is missing a few teeth. The treats are a softer biscuit & stay that way ias long as they are tightly sealed. They are easy to break into smaller pieces, so the dogs think they get lots of treats, but they don't get lots of calories. They come in 2 sizes: for small/medium dogs & medium/large. I find the smaller size easier to break into smaller pieces. Lately, in my local area, they have been harder to find in the grocery store - especially the smaller size. The pet superstores usually have them - but at a premium price. I do recommend them as a regular treat - but if you are hoping for an improvement in your dog's breath, these may disappoint.
