On July 31st my dog Ozzie licked some incesticide which caused immediate vomiting. He was taken to the vet immediately and the vet called poison control who said that he did not get enough to cause any lasting effects and the vet gave him a famotidine
shot and sent him home. He seemed fine after that but then on 8/2 had diarrhea all day. Called the vet back and it was attributed to the stomach
upset that he'd experienced from the poison incident. The problem was gone by the next day.
Since then however it seems that Ozzie is having at least one day each week of diarrhea. Tonight is at least the 4th time this month that he has had it. It usually begins after his 30 min run (in the evening) and then it will last all night until the next morning. After that everything goes back to normal and he is fine. There is no blood in the stool at all but he is definitely straining and after he goes a couple of times he will just strain and nothing will come out or just a little bit of liquid, like a few drops. On 8/10 he began taking Metronidazole, 500 mg twice a day for 5 days. He finished all the medication successfully and seemed fine during the duration of the meds.
He is back to having diarrhea tonight. One thing I noticed was that last week the night before he had diarrhea, he had bad gas. I noticed this in the bedroom when we were sleeping that night, but the diarrhea didn't start until 6pm the next evening. The same thing happened today. Last night when we went to bed I noticed that he was having bad gas and now today he is having diarrhea again.
I'm not sure what to attribute this problem to. There has been no change in diet, no change in exercise (he always has his 30 min runs in the evening ever since I've had him) no change in household dynamics or stress. Other than this he acts completely normal. I am thinking to bring a stool sample to the vet tomorrow as one of my other dogs has an appt scheduled but I'm not sure what else to do or check.
The only thing that I can think of that is different is that my roommate has a cat who has been insistent on going in the backyard lately. I think she is going to the bathroom out there and a couple of times I have caught Ozzie digging in the dirt where she hangs out. I always stop him when he does this but I can't guarantee that he hasn't swallowed any cat poop. He is never left in the backyard unattended so I don't believe he could be eating anything else.
