My three year old chihauhau has been with us about a year now, we found her outside of our auction house running back and forth across the busy highway and we took her home. Ever since we've brought her home, she's had some issues. At least once a month she has a day where she is sick to her stomach and has to eat grass, I typically try to keep her away from it so she won't throw up. Along with this, she has a single poo moment, usually ending up in the house, that is really smelly and dark. It is gelatin like in texture, but it is not bloody or anything. It almost reminds me of fake poo from a novelty store. I've already taken her to the vet and they don't find any parasites around her butt area, although they gave medicine for that anyways. She's also been de-wormed now, I've given her the two treatments the vet told me to do. After those treatments, she was fine for a while..but it happened again. I don't know if it is her food, or if it is just a regular issue, or if I should be more concerned although it isn't but maybe once a month. I was giving her a small bowlful of beneful original every day, but thought maybe she was eating too much at one time so I separated it into two separate meals - one at breakfast and one at dinner.
Anyone have any suggestions as to what I can do? My father gets really angry with the dog, he can't stand her..he's not big on little dogs, we've always had chows. I just want to help her get better, and also appease him from getting angry. Thanks for the help ahead of time!
