The side effects your dog will likely suffer from eating human vitamins will depend on the dog the amount he consumed and the vitamins content.
Your dog will likely vomit blood if he received an overdose of Vitamin D. He will also not touch his food but he will drink a lot of water from excessive thirst. As a result he will be peeing a lot more than normal. Additionally he could have bloody stools and constipation as well as general weakness. You should pay attention if your dog seems limp and not himself. You may notice that your fur child drools a lot has abdominal pain tremors and seizures. Things are not looking good.
Things get a bit tricky when it comes to iron. He may be seriously ill they seem to be recovering and then he may suffer liver failure. Therefore it is often difficult to tell when dogs with iron poisoning are actually getting better or if they are in the early stages of liver failure. There are several signs to watch for including fever fatigue shock agitation abdominal swelling and collapse. Each of these is a cause for concern.
Xylitol is a nasty substance. We already discussed why xylitol is so toxic to dogs in the section on xylitol but we have yet to discuss the symptoms. Drowsiness restlessness and weakness are common symptoms.
Blood sugar levels have dropped sharply because of this. In addition your poor fur kid might suffer from muscle tremors convulsions diarrhea (often accompanied by blood) increased heart rate and low blood pressure. Hypoglycemia may progress to the point where your dog loses control of his body movements and eventually collapses.
Its serious stuff folks. When you suspect your pup has consumed your vitamins do not wait until he shows symptoms. Seek medical attention immediately. If you notice any of these symptoms contact your veterinarian. Your pet may be in danger.
