My dog has diarrhea for days, vomiting. Could it be an obstruction?

Updated On September 23rd, 2025

Pet's info: Dog | Flat-Coated Retriever | Male | neutered | 7 years and 5 months old | 61.9 lbs

My flat-coat has had liquid B.M.'s for the last 7-10 days. My vet has prescribed Proviable-Forte, a digestive health supplement. He is showing no improvement after 2 days. He still has a good appetite but throws up any little bit of chicken meat that I give him to help him eat the paste. He seems to keep his kibble down but drinks lots of water. I am thinking he may have an obstruction but not sure how to proceed.

It doesn't sound like an obstruction - not impossible, but usually they won't be able to keep their food or water down. So, I think it is less likely. He is probably drinking a lot because of the diarrhea. If you are worried about an obstruction though, you need to get him back to your vet for a follow-up and x-rays. If you want to try something else at home I would suggest this: 1. Give ONE dose of Immodium. They come in 2mg tablets. Give him one tablet. Please, ONE dose only or you will cause other issues. You can use generic - loperamide. 2. No food for 6-8 hours. Nothing. Water is OK. 3. After 6-8 hours then start feeding small amounts of a bland diet every few hours. Bland foods like: scrambled eggs, plain rice, plain pasta, boiled chicken or turkey, human baby foods (meat flavors). No butter, oil or spices on the food. If all if going well do this for a few days and then slowly transition him back to his regular food. 4. Continue the Proviable as directed. If he starts vomiting at any time he needs to see the vet ASAP. Otherwise, try this and see how he responds. Hope this helps. If you have more questions you can always opt for a private consultation where we can chat back and forth. That way you can ask as many questions as you'd like. Best wishes.

    I really hate Blue Buffalo foods. I can't tell you how many dogs have diarrhea and intestinal issues with their foods. You need to be very careful with peanut butter as it is very high in calories and dogs get overweight eating too much of it. Also, a lot of brands contain xylitol which is toxic to dogs. Read labels carefully. I would suggest this protocol to get the diarrhea to clear up. The blood is really not a concern. It is just from straining and colonic irritation. 1. Give ONE dose of Immodium. They come in 2mg tablets. Give him 1 tablet. Please, ONE dose only or you will cause other issues. You can use generic - loperamide. 2. No food for 6 hours. Water is OK. 3. Then start feeding small amounts of a bland diet every few hours. Bland foods like: scrambled eggs, plain rice, plain pasta, boiled chicken or turkey, human baby foods (meat flavors). No butter, oil or spices on the food. No carrots, treats, etc until the diarrhea has been cleared up for at least 5 days. 4. Also, start him on a probiotic made for dogs. No human products. You can buy them at any large pet store. I would give it for a minimum of two weeks. 5. Once there has been no diarrhea for 48 hours you can transition back to the regular diet. Hope this helps. Best wishes.

    I suggest you do the following: 1. No food for 6-8 hours. Water is OK. 2. Give ONE dose of Immodium. You will have to use the liquid (1mg/7.5mls) as the tablets are too large for him. You can give him 1/4 teaspoon. ( https://www.walmart.com/ip/Equate-Anti-Diarrheal-Loperamide-Hydrochloride-Mint-Flavor-4-fl-oz/22211158 ) 3. After the fasting, you can then start feeding small amounts of a bland diet every few hours. Bland foods like: scrambled eggs, plain rice, plain pasta, boiled chicken or turkey, human baby foods (meat flavors).No butter, oil or spices on the food. 4. Also, start him on a probiotic made for dogs. No human products. You can buy them at any large pet store. I would give it for a minimum of two weeks. 5. If the diarrhea continues longer than 24 hours after starting this protocol, or if the blood in the stool continues, or if he starts to act otherwise ill, he will need to see a vet. Hope this helps. Best wishes.
