Young puppies have to be dewormed every two weeks until they are three months of age, then dewormed every month until they are six months of age. After that, they should be dewormed every three months. Your breeder probably did deworm Patch, but it can take at least two treatments for all the worms to be killed. The first kills the adults already present, while the second kills the ones that had not yet hatched at the time of the first deworming treatment. He will be ok until Thursday, but if he does start having diarrhea or vomiting (heavy burdens of worms can cause this), I would take him into the vet sooner. As for the sores on his skin, that could be due to fleas. If he isn't up to date on his flea treatments, you will need to treat him for fleas. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home.
