Anal glands carry smelly fluid and occasionally need to be emptied. Many dogs empty their anal glands every time they poop, but occasionally the sacs fill with fluid and your dog needs some help to release the fluid.
Dogs are ideal hosts to worms and other parasites. Most worms that infect dogs including roundworms, tapeworms, hookworms, and whipworms live in the intestines. There are many safe ways to de-worm your dog. The sooner the worms are gone, the sooner your pet will get healthy and feel better.
