Oh no, poor Fat Boy! You are correct that worms could be causing the diarrhea, but if he was being starved, the sudden change in diet could also be causing the diarrhea. I can give you a home remedy to try to see if that helps. Withhold food for 12-24 hours, then feed a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. With the deworming, he will need another deworming treatment two weeks after the first to kill all the worms. After that, he should be dewormed every three months.

    Diarrhea and throwing up can be caused by a food sensitivity, dietary indiscretion, intestinal parasites, an intestinal blockage, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Chicago for 12 hours and then put him on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the diarrhea or if the vomiting increases, or if your dog gets lethargic, he needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.

    You can see diarrhea after a deworming treatment, and it should clear up in a day or two. I can give you a home remedy for Meeko to see if that helps. Feed him a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If the diarrhea continues on the bland diet, he starts vomiting food, stops drinking water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. I hope this helps!
