Some dogs, just like humans, are more likely to suffer from plaque and tartar. To avoid recurring cleaning at the vet, we recommend that you start brushing the teeth with a young puppy. A regular soft toothbrush could suffice for this.
When the teeth change from puppy to adult teeth, the mouth is often very sensitive. It may be a good idea to temporarily not take such intensive care of the teeth during this time.
If you start practicing at a young age, it will be something that comes with it for the rest of your life.
