WOW.....That vet never should have done that.....Vaccines are supposed to be done
one at a time, including rabies....Each one is supposed to be spaced apart by 4 weeks....When multiple vaccines are done it's like a person being hit by 4 different viruses all at once, that is way too much for the immune system to handle, along with the preservatives in the vaccines.....
When more than one vaccine is given the first vaccine will block the others from even working......Most people don't give the kennel cough vaccine, this is a
very mild condition
if the dog where to contract it. It's equivalent to us getting a cold. Lepto is another vaccine most people do not do, Lyme is questionable also. I'm shocked by this, apparently this vet is lacking in knowledge about administering vaccines and the complications that can occur.....
This is a schedule that is very helpful to use as a starting point if your in need help:
