Bath time should be a fun time. Throwing your dog into the water will not help. The bath should be filled and if the noise of the running water scares your Boxer, you can prepare the bath without him or her in the room. The water should be warm. Use your wrist to check the temperature. If it feels hot to you, it will be too hot for your dog.
Sadly, many owners do not understand the vital importance of dental cleaning for their dogs. It is extremely important to brush your Boxer's teeth at least once per day. While a dog does not get as many cavities as humans do, they quickly build up plague. This causes very serious health problems if cleaning is not done. Beginning when a Boxer is a puppy, dental cleaning should be part of a daily routine.
