Your dog relies on you to keep him happy and in good health. A good diet, regular exercise and grooming, vaccinations and routine check-ups are all vital to keep dogs in peak condition. But it's also important to get to know your dog's routine, whether it's eating, drinking, sleeping or playing. Often a variation in a dog's habits can be an indication that he or she is not well. Many health issues can affect dogs. Some breeds are more prone to certain problems. Being aware of your dog's behaviour gives you a better chance of spotting when a problem arises. And catching the problem early will help put your dog back on the road to good health and prevent the possibility of more severe health problems arising.
