Neurotoxins affect smaller animals more than they do larger animals. I did a whole study in grad school on metabolism and the animal’s size. Vaccines have the potential to cause more harm to a dog or cat than a human.
And *why* is the rabies dose for a teacup Chihuahua the same as for a Great Dane?
*My* rabies shots were geared to my weight and I *still* had terrible side effects.
What is it doing to the dogs, who cannot tell us how they feel?
