My Siberian Husky (DIVA) has on ocasion suddenly vomited bright yellow bile! any body have any idea what may be wrong? she is eating normal but for some time has had the odd loose bowel then returns to normal the very same day? and now she is vomitting then back to normal again? I understand these dogs are very fussy eaters and very little change can upset them but this seems very odd! in all other ways she is a perfectly happy/active Husky.
