The average spay or neuter vet surgery is $110 to $175. This increases with larger dogs. The more a dog weighs, the higher the price. One clinic charges $213 for a 50-pound dog surgery spay and $169 for a 50-pound male dog. If the female is in heat, the cost increases more.
They are usually spread like this: 1  A child swallows pinworm eggs, and they travel to the child's intestines. 2  In about a month, the eggs hatch into worms. 3  At night the female worms crawl out the rectum and lay eggs around the child's anus. 4  When the worms lay eggs, it can cause itching.
The eggs hatch in the small intestine, and the baby worms grow and move on to the large intestine. There, the pinworms grab onto the wall of the intestine. After a few weeks, the female pinworms move to the end of the large intestine, and they come out of the body at night to lay their eggs around the anus.
