  Any puppy having that much diarrhea needs to be seen by a vet. Diarrhea can make them dehydrated even if they are still drinking water. The reason for the diarrhea could be diet change but it could also be from internal parasites (worms) or it could be from a virus (like parvo). I strongly suggest you get Elsa to a vet for an exam. She definitely needs to be eating puppy food, I can tell you that and really, dry food would be best to give over the canned food. Hope this helps. Best wishes.

  Poor Piper! There are a number of reasons why she may be having diarrhea. If you just brought her home, stress from being in a new place may be causing some GI upset. If you've also switched her food suddenly, that can also cause GI upset. Feeding the same food she was eating at her old location, or offering a bland meal of boiled chicken and rice and gradually switching over to the new food, as well as giving her a few days to settle in may help settle her stomach. If she is having severe diarrhea, is lethargic or refusing to eat, has other symptoms in addition to the diarrhea, seems dehydrated, or you are seeing blood, worms, or other issues with the stool, then a trip to the vet before your already schedule appointment is a good idea as puppies can quickly become dehydrated if they are ill.

  Dogs don't usually get a "cold" like humans do. The symptoms you have mentioned (decreased appetite or anorexia, vomiting, diarrhea) can be caused by many things, some serious and some not so serious. Common causes of these symptoms in a puppy include food intolerance or allergies, intestinal parasites, dietary indiscretion, bacterial or viral infection, stress colitis, among others. One virus that can cause these symptoms is parvo virus. This can be a life-threatening infection. I would strongly recommend that you have Sasha examined by a vet as soon as possible so that her illness can be diagnosed and the appropriate treatment can get started. Until her appointment, continue to encourage her to drink water or pedialyte to stay hydrated. You can offer her canned or dry puppy food, baby food, or small amount of boiled chicken breast.

  HI, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Little Bit! A normal temperature for a a dog is 100-102 F rectally. A temperature of 101.3 is normal. I don't go by ear temperature, nose wetness or dryness, etc. There sadly is no rhyme or reason to that. I am glad she stopped vomiting and is eating (hopefully). Possible causes of vomiting and diarrhea in a puppy are: intestinal parasites, viral (parvo being the big one) or bacterial infections, ate something gross outside that is upsetting her stomach, food allergy or intolerance or toxin ingestion. If she is eating and not longer vomiting I would feed her a bland diet of boiled chicken or hamburger with rice. Feed 1 cup per 20 lbs per day until 2 days or normal stool. If she is not eating, starts vomiting again or the diarrhea isn't improved by Friday she should see your Vet. Once she is better, it is very important to have her seen by a Vet to start her vaccinations and have her dewormed. I hope this helps and I wish Little Bit a speedy recovery!
