With an electric probe, a laser beam, or an infrared light, your doctor will make a tiny burn to remove tissue and painlessly seal the end of the hemorrhoid, causing it to close off and shrink. This works best for prolapsed hemorrhoids.
Shih Tzu puppies need three meals per day. Race Foster, DVM, recommends on the Pet Education website to feed 8-week-old puppies three times a day. In addition, Dr. Foster recommends feeding puppies on a consistent schedule instead of leaving food out for the puppy to eat during the course of the day.
They can get bored with eating the same meal all the time - why do you think dog food comes in different flavours? As to how much they eat, that is going to depend on the dog. A Saint Bernard will eat more than a wolf would, a Chihuahua a lot less. In the wild, wolves usually only eat around once a week (nine hunts out of ten end in failure, and they obviously only get to eat when they've made a kill).
