When I first had dogs of my own, I gave them a huge raw beef bone daily which they worked on for at least an hour a day. Little did I know this was natures toothbrush as the vet couldn’t believe how perfect their teeth were from it. You can buy a toothbrush for your pet as an alternative. Please look out for forbidden ingredients in the pet toothpastes on the market. I use pure tuna mousse for my dogs ‘toothpaste’ because it is not the toothpaste but the brushing that is important. The tuna mousse is only a motivator for them to look forward to having teeth brushed.
