Why did my senior dog vomit after eating human food and a burrito?

I would recommend taking him back to the vet if he is still vomiting. Those type of treat are very high in fats and salts. This could lead to sever gastrointestinal upset or even pancreatitis. Most patients will need medications to help stop the vomiting if the stomach has become very inflamed. I would recommend a bland diet of boiled chicken and white rice for at least 24 hours and staying away from high fat dog treats.

You could feed boiled chicken breast and cooked white rice and see if she feels better within 24 hours. If she doesn't want to eat that or she continues vomiting she should probably get checked out by a vet since she is an older girl. If she isn't normally bothered by thunderstorms, then it is unlikely that they would cause her to lose her appetite this morning.

Throwing up can have many causes such as a problem with the stomach and intestines caused by a food over sensitivity, eating something that does not agree with the dog, intestinal parasites, an intestinal blockage, bacterial infection, viral infection, the weather, food change, stress, etc.  I would fast Misty for 24 hours and then put the dog on bland food for two days, such as boiled white rice and boiled white boneless chicken meat, fed in small quantities over several feeds and then transition back to regular food slowly over a few days. If this does not clear up the vomiting or if the vomiting increases, or if your dog gets lethargic, it needs to see a veterinarian for an exam as there may be something more serious such as an infection going on.

If this is a new, sudden behavior, it's a good idea to have Jazmine examined by your vet, especially since she is a senior girl. Sudden symptoms like this could indicate an underlying illness, something obstructing the GI tract, or even changes to the tract itself affecting motility. If she is gulping her food down, feeding smaller meals more often may help prevent her from throwing it all back up as well.

Chronic vomiting is always a good reason for concern, it could be a sign of an internal disease such as a tumour, kidney failure or pancreatitis among other things, you should take Wolfie to the vet in order to get it checked, he will need to have a blood test done so the vet can gather some more information.

Some medications might help. Antibiotics and pain killers (anti-inflammatories) can definitively improve his condition clearing up mouth infection. Symptomatic treatment for vomiting might help as well. I would recommend to have him on a bland diet based on boiled chicken and rice. Please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

I would recommend having Oliver examined by a vet. Vomiting in an older dog is always a little concerning for issues such as liver or kidney disease, pancreatitis, IBD, etc. Once he isn't vomiting any more, switching to a senior diet is a good idea.
