Brushing my puppies teeth is a really impossible task sometimes, and I am actually a dental hygienist for my profession. I love the idea of cleaning all 3 surfaces of the teeth at the same time. It is a cute, bright colorful design and seems to work well. My one complaint is that the side bristles are touching which makes it a little tricky to place the tooth exactly in the middle. I wish there was just a little space in between the side bristles for the tooth.This toothpaste is usually good. But the front picture show that it is vanilla flavor. However when I received it, the flavor was vanilla mint. My dogs do not like the mint flavor. After reviewing the other pictures and zoomed in, it said vanilla mint. I feel the front picture is misleadingI previously had the older version that contained tea tree oil and it just said flavor not vanilla. I have tried many other toothpastes since. The enzymatic toothpastes all gave my dog diarrhea so did the gel. I look up all ingredients for safety firstHe has pancreatitis issues. I ordered this toothpaste and noticed that the tea tree oil was not on the label of the actual toothpaste. I was also wondering about the vanilla flavor. I did have concerns as tea tree oil was a concern from what I had read, but other sites said it was okay for fighting bacteria. We tried it and he loves it. When he sees my husband with his toothbrush and he can smell the toothpaste he gets excited. My husband sits on the couch, and Griffin jumps right up next to him ready to go. No health issues at all with this toothpaste.I’ve had this brush for my dog for a while now and we’re still using it a few times a week. I should probably buy a new one. I used to use those little finger brushes with the super flimsy bristles, but it was awful because my dog would just bite me. This brush is great because it is really sturdy. My dog gets excited about the toothpaste and starts biting this brush, and it’s fine. He basically brushes his own teeth because he’s biting and it’s catching bristles on all three sides. I do slight back and forth motions, especially on his front teeth, but for his back teeth I mainly just push the brush in as far as I can comfortably get it and then I let him chew a little.Make sure when you’re adding toothpaste to the brush that you spread all the bristles apart with your fingers. Otherwise, the paste will just all come off as soon as you start brushing.Brush could be a bit bigger for a large dog. Otherwise greatI previously owned this style of toothbrush a few years ago for a previous dog. I decided I probably should start brushing my current dog's teeth. (Ok, I mostly did it for selfish reasons, because his breath smells awful...but I'm also glad its good for his health).I purchased one of these because I had used it in the past. I used it a few times and thought "Hey, I probably can clean his teeth better if I use a regular toothbrush, then I can be sure to get all the sides and surfaces.Well....good idea. If your dog is impeccably trained. My dog is super tolerant, he doesn't budge when they take his blood at the vet etc. He really likes the toothpaste so he doesn't fight me at all, but for me to think I could brush all the surfaces of his teeth "better" myself with a regular toothbrush was seriously misguided.He likes the toothpaste so he's licking and moving his mouth etc. This toothbrush gets the job done in the least amount of time, and its better than not doing it at all.Save yourself some time and headache and just get this.I found this covered my dogs molars completely and his K9's enough for me to be satisfied. He is a 110lb American Bulldog with very large K9 teeth.We found our dogs didn't like this toothbrush. I found it difficult to work with and I couldn't really get it to brush both sides of their teeth. We went back to a regular angled brush. We have 2 Cockalier spaniels that are used to tooth brushing 2x a day.My beagle likes it and so did the two beagles we had before her. Helps keep tartar from building up and keeps her breath smelling much better.
