Intestinal worms are common in puppies and could be the cause of Woodford's diarrhea. It could also be that he has a stomach illness. Make sure his deworming treatments are up to date, and I can give you a home remedy for him 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 refuses to eat 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!

    Poor Luke! In puppies, a very common cause of diarrhea is intestinal worms, and if he isn't up to date on his deworming treatments, you will need to get one for him. I'd recommend giving him Panacur. He will need another deworming treatment in two week, as it will take at least two treatments to kill all the worms. The first treatment kills the adults present, which the second kills the one who had not yet hatched at the time of the first treatment. Luke will need then a deworming treatment once a month until he is six months old, then one every three months. If he is up to date on his deworming treatments, then his diarrhea could be caused by GI illness, eating something rotten, or a foreign body. You can try a home remedy to see if that helps before having to take him to the vet. 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.
