Hello JACustomer. It looks like Dr. Gabby had to step away for a bit, so she has opted out and allowed another expert to step in to assist.
Its very possible with the vomiting that the pizza crust could be causing this. In fact, we find that people sharing food is one of the top concerns with vomiting (and diarrhea, if it occurs) in pets. Your choice to go to the ER today is not a poor one. If nothing else, this will allow the vet to administer medication for nausea to help stop the vomiting. I can also give you some directions to try at home to see if you can get the vomiting stopped without ER intervention. If not, however, you'll still need to go so that your companion does not dehydrate with the persistent vomiting.
The first thing is to administer a dose of regular pepcid (famotidine) every 12-24 hours. You will want to give 0.5mg/pound of body weight (a 10# ***** would receive 5mg, a 5# ***** would receive 2.5mg, etc). For this, you can buy the brand name Pepcid, or you can use the cheaper, off-brand “famotidine” that’s available. Either will be useful.
2 hours following this, you can either offer a bland diet of boiled chicken and rice or a few teaspoons of pureed chicken or turkey baby food to see if your companion is interested and can hold the food down. From there, try to increase the amount every 30-60 minutes. If vomiting occurs, you're back to the recommended ER visit. However, if the vomiting stops, you can eventually wean over to dog food and monitor for changes.
