Heartworm is a serious problem in certain parts of the country and also requires preventative measures. Spaying and neutering will benefit your dog's health. Contrary to popular belief, spaying and neutering won't change your dog's personality or make it fat and lazy. Brush your dog's teeth regularly. Dog toothbrushes and paste are available, quite effective and even enjoyed by most dogs.
Regular grooming is an important part of helping to control ticks, lice and fleas.
Avoid supermarket gels. Ask your vet for a recommended flea control product. Home, yard and your pet are all sources of fleas and must be attacked at the same time. Some barking is normal for a dog. If it seems excessive, find out why.
