Loki has had a history of having random diarrhea and vomiting. Since we got him as a puppy, he's been to the vet at least once a month, and we've come home with a prescription for Metronidazole. He's also been stuck in the butt at least once a month, etc.
We thought that the diarrhea was because of allergies or whatever, so we switched his food to raw and grain free. That cured him of constantly chewing at his feet and itching his snout. But no avail on the diarrhea. That continued up until sometime in the beginning of January, and he's been fine since then.
I took him to the vet today because he's been playing with my friend's two puppies - one that was diagnosed with Coccidia two weeks ago, and one diagnosed with worms last week and he's been having diarrhea for about a week now. Apparently, we used up all our fecal samples through Banfield, so I had to pay for that. When the fecal test came back negative, they decided to test for Giardia since I told them about him playing in the lake and at the beach. Plus, they figured with him being such an active dog, it wouldn't be hard for him to get into something.
Negative negative negative. He had NOTHING (which, don't get me wrong or anything, if he had something, it'd probably be all the more expensive. But I spent $50 for them to tell me that he's fine!)!
Right before we left, the vet mentioned something about Loki being stressed and reacting to it by having diarrhea. I joked that he was just a dog, and what does he have to be stressed about?! Well, she mentioned something about Jason being gone for a longer period of time (i.e. a pack member being gone) and said that that could be a very good reason why Loki's having stress and diarrhea.
Got home and looked at this website.
"Apparently the "stress" of the new environment, possible kennel noises during the night and separation anxiety from missing his owners triggered a hypermotile gastrointestinal tract. The rapid passing of intestinal material creates stool that did not spend enough time in the large intestine to have the usual fluid reabsorption processes take place. Since semi-fluid intestinal contents must spend some time in the colon to have fluid reabsorption take place so that firm stool can be passed and rapid transit or early expelling of stool will result in loose feces rather than firm or hard feces. As in this specimen, even small amounts of blood will occasionally be seen in loose stool of neurogenic origin."
Also, "Neurogenic diarrhea or loose stool is seen in dogs that are boarded, suffer from motion sickness or travel stress, are suddenly placed in physically demanding situations or are frightened from storms or strange situations."
Sigh. Poor Loki.
