Teeth- Most experts recommend daily brushing of your Boxer dogs teeth. Teeth problems such as excessive plaque is linked to more than just gum disease- many serious health issues (including heart disease) can be linked to the mouth. Brush daily (or at least weekly) with a finger brush or canine toothbrush with a drop of canine toothpaste to prevent your Boxer having bad breath.
Ears-You may check the ears every couple weeks but, in general, your Boxer will need monthly ear cleaning. Ear cleaning solution can be purchased from your vet or local pet store. A rag or cotton ball dipped in the solution works well but you can also use QTips to clean the outer area.
Eyes - Boxers have large eyes that need to be wiped with a damp washcloth as needed to prevent tear stains or gooey buildup.
Wrinkles - This is a site of bacterial and yeast buildup if not kept clean. Every month you can take a QTip with baby oil (or unscented oil) and run it in between the wrinkles to remove dirt.
