Welcome! My name isXXXXX am a 2003 graduate from UC Davis, and currently a Medical Director of a veterinary hospital.
I am sorry to hear about this concern for Mumbles.
Before throwing more drugs at this problem:
1. Got to get a fecal test done to rule-out possible giardia causing illness.
Bring in a fresh poop sample to the veterinarian. Ideally, within a few hours. Request that it be sent “OUT” to the laboratory instead of being looked at in the hospital (more accurate that way). We are not interested in only worm eggs, but also checking for the very common microscopic bugs like giardia and coccidia. These types of parasites will not be cured with over-the-counter dewormers. Giardia can also be difficult to identify on routine fecal tests, so ask your vet if they always add a “giardia elisa” to the fecal test. Here is more detailed information about fecal testing:Fecal Testing
2. With THIS MUCH repeated vomiting, abdominal x-rays are a must to check for a retained foreign body. This is a critical test.
3. I would now ask the vet to do a simple blood test called a PLI. It is very accurate for assessing for pancreatitis, a common cause of repeated vomiting, and would help to determine if Mumbles should be hospitalized.
Well, you are trying a bland diet.
I would start an antacid for sure.
To help settle the stomach you can use of the following, but not as a replacement for veterinary examination include
1.Pepcid A.C. (famotidine) comes in 10mg, 20mg, or 40mg tablets.
You can give it every 12 hours. You can give 0.5mg per pound of body weight. So, a 20 pound dog would get 10mg.
2.Prilosec (omeprazole). It comes in 10mg or 20mg tablets.
You can give in every 24 hours. You give 0.5mg per pound of body weight. So, a 20 pound dog would get 10mg
3.Zantac (Ranitidne). It comes in 75mg, 150mg, or 300mg sizes.
You can give it every 8 to 12 hours. You give 0.25 to 1mg per pound of body weight. So, a 20 pound dog would get roughly 1/3 tablet of the 75mg. Even with bigger pets, it is easiest to get the smallest size tablet. Even a 75 pound dog would only need one 75mg tablet.
Not sure what antivomiting pill was prescribed, but one of the best and now most commonly prescribed by vets is the once a day medication called Cerenia. Excellent for vomiting!
Tarry colored feces suggests there was bleeding in the esophagus or ulceration in the stomach. So, also ask the vet to start Carafate (Sucralfate), which can help the stomach to heal.
I hope that information has been helpful.
