Brushing your dogs teeth is extremely important for your dog's health. Bad mouth hygiene can lead to serious problems such as gum disease and even bigger issues down the line. Small dogs in particular are more prone to bad breath and mouth diseases. Although dogs are not as prone to cavities as humans are, it is important to brush daily to prevent illness and bad breath.
You can buy a dog toothbrush at any pet store. Make sure when you start, you are brushing down from the gum line to try to remove as much plaque as possible. Your dog will most likely fight back against you initially, but that is okay! It is a process and will take some easing into, but be patient. Try choosing a time of day they tend to be more calm to clean their teeth. For some, brushing their dogs teeth after they are tired from exercising leads to the most successful period of stillness.
Start slowly and for a short period of time, even if you don't finish their whole mouth. You just need to get them used to it. You can even start with a finger brush which is easier to use than a bigger toothbrush. Talk to your dog in a pleasant voice and reward them with a treat afterwards to get them adjusted to the experience in a more positive light. Eventually, they will get used to it and you will be able to brush for longer periods of time.
To ease into this process as seamless as possible, try to start brushing as early as you can. If you get your dog when they are a puppy, it will be much easier for them to get used to the routine. If you do get an older dog, you can still teach them that brushing is okay, but it might take a little longer for them to adjust.
Be very careful NOT to use human toothpaste on your dog! The fluoride is toxic for them. Dog toothpaste is readily available at pet stores or you can try coconut oil.
Lastly, make sure you are giving your dog hard food, which can break up the tartar and plaque while they chew. Always have good chew toys and bones around for them not only entertain themselves, but many chew toys aid in preventing plaque build up. If you ever see bleeding, swollen gums, a change to bad breathe, missing teeth, or a yellow-brown tartar crust along the gum line, please see a vet as soon as possible.
Make sure to provide proper and frequent mouth care for you dogs and give them Flea Away daily to fight flea and tick infestation.
