i have a year old mixed breed maltese and lately his stool has been soft and close to being liquid. just a few minutes ago he went and only had droppings that were yellow and mucus-y. earlier this morning he had gone and his stool was soft, but it was like very thick liquid. the other day i noticed he was scooting/dragging his behind after he pooped a white mucus-like dropping. he's been eating a mixture of soft and dry food. cesar for soft and beneful for dry.
yesterday he vomitted the the food he just ate (cesar) so that night i gave him boiled chicken and rice, which he was able to keep down. also, he's been vomitting a lot lately. though, not everyday, he'd vomit yellow bile which i noticed occurred after his shot were updated. i don't know if that's the cause or just a coincidence.
right now i can hear his stomach growling but now like hungry growl, more like the sound of stomach acid.
what could the possible causes be? i know he licks his paws a lot and loves to go on grass.
should i continue giving him the food he usually eats, or just continue with the rice and chicken? any food recommendations? thanks in advance!
