Vitamins are essential for dogs just as they are for humans. Its unfortunate that whats good for us is potentially harmful to our furry friends. Among the worst culprits are vitamin D vitamin A and iron. If your pet consumes any of these it can die. In the case of sugar-free vitamins xylitol is likely to be present which is even worse. More on that later.
Your pup will experience muscle tremors and seizures when he consumes too much Vitamin D.
Dogs suffering from iron poisoning experience shock and toxicity.
Vitamin A will have long-term effects on the coat and skin of your dog if he receives regular doses. His hair will become dull and lack its usual shine while his skin will become dry and itchy. He may even become paralyzed.
Your pup will suffer immediate and severe side effects from large doses of vitamins. There are times though when they regularly consume a little bit of the stuff not too much at a time but enough to have long-term effects. Watch out for any signs of illness in your pup or unusual behavior.
