Hello, my name is***** and I have over 20 years of experience as a veterinarian. I am sorry that your pup Chico has a poor appetite suddenly today. Lack of an appetite can be related to eating something he should not have, too many treats
or table food, eating foreign material (which could cause a full or partial gastrointestinal obstruction), chronic pancreatitis
, a dietary allergy or sensitivity, toxin exposure, a viral or bacterial infection, Addison's disease (hypoadrenocorticism), inflammatory bowel disease
, or even infiltrative cancers such as lymphoma
.If he isn't drinking well either he will quickly become dehydrated.Ideally he would see a veterinarian if this continues for more than 48-72 hours. Simple stomach
upset should pass within 24 to 48 hours. They could examine him, run blood tests and possibly check radiographs and/or an ultrasound to evaluate him and know best how to treat him.In the meantime they can administer injectable anti-nausea drugs and fluids to rehydrate him.Tonight there are some things you can try at home.At home to try and settle his stomach you can give either:1) Pepcid ac (famotidine
) at a dose of one 10mg tablet per 20 to 40 pounds of body weight every 12 hoursOR2) Prilosec (omeprazole) at a dose of one 10mg tablet per 20 to 40 pounds of body weight every 24 hoursThese are acid reducers and may help him feel less nauseous so that he will eat and drink. They are quite safe and can be used for several days if necessary.A couple of hours after giving the acid reducer I recommend offering meat baby foods or a bland diet of 1/3 boiled, minced, white skinless chicken
or boiled, lean hamburger and 2/3 boiled white rice mixed with some low salt chicken or beef broth to make it easy to lap up and swallow.If he continues to not eat he should see his veterinarian for an examination, diagnostics and intravenous fluids and supportive care.Please let me know if you have any further questions.
