The tartar by dogs is caused with neglect of the interventions by owner. Initially on the teeth puts away the clearly-yellow sediment in which form the plaque, of clearly-yellow stain. If the interventions aren't continuing, from plaque, form tartar.
The tartar causes teeth-illness and gums-illness, which leads to loss the dentition. Therefore you shouldn't make nothing of oral-hygiene of your dogs. You ought to brush dog's teeth at least once in week. In the zoological shops you can buy the tooth-brushes and the tooth-pastes for your dogs. It costs from 10 to 15zł. I prefer putting on a tooth-paste the piece of gauze winded round about the forefinger, the dog is calmer and you can reach to the every tooth. Firstly, dogs don't like it but if you repeat it more times, they get used to it and in small time the collaboration will be great.
It is said that instead of tooth-paste you can use oxidizen water, lemon's juice or clear soda ( flat spoon on glass of water). These means aren't as good as tooth-paste, so if you use their, you shoudl repeat brushing more times than if you use tooth-paste.
Remember, our dog should get to gnawing porked and beefed bones, thanks to them he mechanicly removes sendiment from teeth. Alike is with the tougher bones. You can also buy the poorly caloric bones "denta" which you can find in zoological shops.
Finaly tartar can be removed by the veterinary surgeon, but dog must get the narcosis, although the risk isn't big, always is waking up of dog from narcosis, it isn't agreeably survive. This method is the most efficacious, it costs from 50 to 80zł. Do your best to avoid having by your dogs tartar!
