You should withhold all solid food (treats, biscuits, food, scraps). Also, pick up the water bowl and offer only ice chips periodically. Common causes include “dietary indiscretion“ like bottom-feeding in the kitchen trash, foreign material in the stomach or intestines (we’ve removed dish towels, telephone cord, rocks, underwear, golf glove, socks, and one neatly chopped police duty belt from pets’ intestinal tracts). Call the office or our emergency referral hospital for more specific advice.
