Chronic vomiting, has multiple causes but may cause an electrolyte imbalance which could account for the symptoms you are seeing. If he is drinking more water than usual, he should be seen by your vet for an exam and bloodwork to rule out kidney disease, diabetes or other GI issues. When a pet is vomiting, withhold food for 12-24 hours. Allow small amounts of water or unflavored PediaLyte. Resume feeding a bland diet (1:1 ratio of plain boiled boneless chicken and plain white rice). Feed in small, frequent amounts waiting at least one hour between feedings. If he won't eat, serve the food warm or mix in a teaspoon of baby food to stimulate the appetite. If the vomiting stops, transition slowly to the regular diet. If not or if the appetite does not return, then you will need to see your veterinarian.

    Thank you for contacting Petco Pet Education Center, formerly Petcoach with your question about Joey. Oh no, poor boy. Feed him a bland diet of boiled white meat chicken (no bones) and white rice in small amounts several times a day for a couple of days. Then slowly add back in his normal diet. If he refuses to eat the bland diet, he vomits the bland diet, develops diarrhea, continues to not drink water, starts vomiting water, or becomes very lethargic, he will need to see a vet right away. I hope this helps!

    Reasons for this could be parvo, food indiscretion, intestinal obstruction, gastritis and other. Take your dog off food for about 12 hrs, then feed bland food such as boiled rice with boiled white chicken meat in small quantities over several small feeds a day,. Do this for a day, then start replacing small quantities of rice with his normal food over the next two days until he is at the normal quantity of his regular food. If the vomiting persists, or your dog is lethargic and dehydrated or deteriorates you will need to take your dog to a veterinarian for an exam.

    I'm sorry to hear that Mabel hasn't been feeling well recently. Try to encourage her to drink water so she does not become dehydrated. You can hold her off of food for 12-24 hours depending on her size. Resting the GI tract can resolve simple causes of vomiting. If this does not help, she will need to see her veterinarian. I hope this information helps!
