We have an older dauchshund. I'm unsure of her exact age...perhaps 13+. She has a funny bite...always has. It probably contributes to extra tarter on her teeth. We've had her teeth cleaned professionally twice before and we are seriously considering having it done again. She is showing signs of old age...a little arthritis, mostly. She had a bad spell with that this weekend and is on an anti-inflammatory and Pepcid. This is the first time she has had to take something for it. She has very bad breath. We sometimes spray her mouth with a doggie breath spray. When she was younger, we would brush her teeth now and again. She hates it. We also sometimes gave her some doggie stuff in her water to help with tarter prevention, but I don't trust it at all and stopped. She has urinary stones! She's had two surgeries for that. So, my question is, does anyone regularly brush their dog's teeth with success? What do you use? Do those greenies work well? I hesitate to give her those, because last time she had those (I probably over did it...,not sure) she had THE WORST DIAREAH IN THE WORLD and I almost had to evacuate the house. If you have success brushing your dog's teeth...what do you you use for paste, brush, and how often? Thank you.
