My name is***** and I am sorry to hear that your pup is vomiting tonight.
You did the right thing by trying to get her to take the pedilyte this weekend as this is the best way to hydrate her.
What kind of flea collar was it? This will help me tell you if that is the cause of the problem or if the vomiting is from something else.
Okay, most flea collars (especially the cheap ones) usually are plastic with a coating of a pyrethoid based pesticide.
There is only a little bit of the pesticide on the collar, so you likely won't see toxicity from it. The signs of toxicity include muscle tremors, shaking and hyperactivity.
If she ate enough of the plastic, it could cause a potential obstruction of her intestines.
Other causes of vomiting include pancreatitis, blockage from something else that she ate, liver disease, kidney disease, cancer, and others.
