Why did my dog throw up food and then suddenly collapse or faint?

She is cute! Vomiting can cause a vasovagal response and the animal could have a syncopal episode (fainting) but I don't believe it would cause a seizure. Are you sure your dog is having a seizure and not just fainting? I know of dogs that vomiting because of the seizure but since you actually induced vomiting that doesn't make sense. Here is a link to an article with information on the difference between syncope and a seizure which might be helpful to read...... https://www.mspca.org/angell_services/the-approach-to-the-collapsing-dog/

That's not normal at all, and it seems a bit severe to lose consciousness over indigestion. I supposed if Pisty was vomiting hard enough, it could trigger a vagal response and subsequent loss of consciousness. I'd take her into another vet for a second opinion.

It could be Larz vomited so hard that he passed out. Certain stimuli (such as vomiting like Larz did) affect the vagus nerve which has receptors in many areas of the body including the esophagus and stomach. This, in turn, causes an overload to a part of the nervous system leading to a rapid drop in the heart rate and blood pressure resulting in fainting. I'd keep a close eye on him, and if he vomits again, have him seen by a vet.

Hello and welcome to Petco Pet Education Center, formerly Petcoach, Sometimes when animals vomit the pressure on the vagal nerve causes a fainting episode. Animals should recovery completely and quickly from this. Since Sqwrt is so young, and hasn't fully recovered, I recommend you have him seen by a vet. They will check him for an upset stomach, might suggest x-rays or bloodwork, and might give him some medications. Best of luck with Sqwrt, I hope he feels better soon!

I'm wondering if Jax may have had a vasovagal episode after vomiting. This is a reflex that sometimes occurs after vomiting and results in a low heart rate and low blood pressure, and sometimes even collapse. While it is not necessarily a sign of something more serious if the vomiting continues or another episode occurs I would recommend seeing your veterinarian so they can make sure something more serious isn't going on - low blood sugar, ingestion of a toxin, or even liver disease could also cause similar symptoms.

I recommend to have both your dogs examined by the veterinarian. Just like humans, many diseases can have the same clinical signs and so it is impossible to know the cause without a physical exam and likely some diagnostics. Being unbalanced and collapsing is extremely concerning for an issue with the heart, blood pressure or the brain. Other conditions can also cause collapse. Fatigue can be seen with many conditions as well and it could range from internal parasites to an autoimmune condition. Have both pets seen within the next day. Diseases tend to have the best outcome if they are dressed early. I hope this helps.

Poor Bella. She may have been trying to hard to throw up that she lost strength and simply collapsed. It could mean nothing, just a reaction to trying to vomit. If this keeps happening, then I would have her seen by a vet. I hope this helps!
