In a young puppy, diarrhea can be caused by viruses and parasites. A stool sample to the vet is a good idea to check for Coccidia (Coccidiosis), Giardia, Trichomonas or other infections. If your litter of two week old puppies gets diarrhea, it could be worms. Normally we do not worm pups till 3 weeks, but some do it at 2 weeks. When worms become active, it can cause diarrhea. If the diarrhea worsens, even after using a worming medicine, you may need to check for coccidia. The incubation period is 13 days, and the Dams often carry it. They would come in contact from the Dam at birth, or shortly after. They are not born with it. If a 13 day old puppy has diarrhea, it often means coccidia. This requires vet medicine to treat. It can be found in a stool sample.
Some dogs/puppies can get diarrhea from the excitement/stress of being away and then coming home.
Some dogs get doggy flu bugs, others may eat a strange food and cause stomach upset.
Diarrhea from change is common. You need to deal with it and not ignore it.
Ignoring diarrhea in a puppy lowers the immune system, and can dehydrate even an adult dog.
Puppies can get a bug much easier if they are down and weak, so diarrhea is not something to ignore.
Ask your vet for a sheet on what to do for diarrhea. Each vet has slightly different versions but they all have a sheet, as it is common.
The following home remedy is for early onset diarrhea. A dog with severe diarrhea, needs Vet attention, as he needs fluids.
The greatest worry with ongoing diarrhea is dehydration.
If you are treating the early onset of diarrhea, and the dog is not showing ANY signs of dehydration, you need to fast the dog for a day - no water no food. (I find that a full 24 hours is to long for a puppy under 8 months, and you may want to give her some bland food throughout the day, (rice and chicken), and a bit of water and then NOTHING until the next morning), small pups try 12 hours. This rests the tummy. For a dog or pup with secondary severe diarrhea (uncontrolled liquid squirts), omitting the water is NOT an option, they MUST have fluids, if dehydration is happening. But if dehydration is not a problem, and diarrhea is early onset, and controlled, omitting water for a bit helps. 12 hours is usually ok for a puppy. It is just to give the tummy a rest. This is easier done at night.
BUT... If the puppy has severe diarrhea, (progressed into more Serious Diarrhea), and dehydration could be a secondary problem, YOU MUST give the puppy water, or better yet, pedialac, or sub fluids (lactate ringer), under the skin intravenously, (talk to your vet). Mild diarrhea is soft stools, or pudding texture, serious diarrhea, is projectile, uncontrolled watery texture - LIQUID SQUIRTS.
Do NOT fast any puppy under 7 weeks. A young puppy, with diarrhea, usually needs medical attention immediately. Pups under 4 weeks can die quite quickly with diarrhea.
It can sometimes be hard to determine the cause of diarrhea unless further testing is done. It is a good idea to take a stool sample to your vet, if diarrhea, cannot be stopped in a couple days, OR if it has blood in it, or if it is watery squirts.
It is important to consume the same amount of fluids as the volume that has been lost in order to prevent dehydration.
So, if your dog has a couple runny poops, omitting water for a bit is ok. (For EARLY onset diarrhea.) To stop diarrhea, before it progresses to secondary severe diarrhea.
BUT... If the diarrhea, has turned secondary, and is coming out as fast as you put fluids in, intravenous may be needed. DO NOT OMIT water on a dog, with uncontrolled severe diarrhea.
Diarrhea can be treated at home in the early stages, and if caught early, turned around. The key with diarrhea is to stop it fast, BEFORE it turns into secondary diarrhea with dehydration. Once the immune system is down, it is an invitation for other problems.
If the dog is vomiting and or has diarrhea, and is dehydrated then you must seek VET attention to administer fluids intravenously. A good test method for dehydration is, if the skin on the dog's neck stays up, when lifted and doesn't drop down instantly in place when released.
RECIPE for early onset diarrhea,
Pepto Bismol every 3 - 4 hours. (You will need a syringe... good luck!)
liquid pink Pepto 1/2 to a tsp each time, for every 10lbs of dog
PEPTO... still highly recommended by the vets. For puppies over 6 weeks old... (for younger pups, call your Vet)
2nd Day: (or first day with puppies)
Boil rice - 1 cup rice, 2 cups water, 1 chicken breast... the chicken flavor permeates the rice, when you cook it together making them LIKE to eat it. (You can use Rice Pablum). Feed ONLY the rice mixture, for the first day after fasting. REMEMBER, if your dog has secondary Diarrhea. Uncontrolled watery squirts, YOU MUST get fluids into him/her. This can be done by syringe, or intravenously.
Another vet recommends a little bit of low fat plain yogurt and a little bit of low fat cottage cheese is added. CANNED Pumpkin is also known to help treat diarrhea... I give it to my lactating Dams.
I feed mine with this RICE mixture, three or more times during the day with small amounts of water.
You can also buy a tube of Nutri-Cal from the vet. It is a toothpaste type tube of Nutrition and Calories and will give a weak puppy, the sugars, nutrition and calories he needs. It is a very good, miracle pick me up paste.
3rd Day: You can start mixing in the chopped up boiled chicken with the rice. (You can also purchase a Gastro food from the vet, which is an easily digested food for this purpose, and start mixing that in too.) The Vet may recommend that you keep the dog on Gastro for quite a few days and then start mixing in his normal food over a period of a few days.
Sweet potatoes are also a natural stool hardener.
If your puppy or dog has diarrhea, that is getting WORSE, not better, call your vet ASAP and follow their advice.
