Why is it when you get a shot at the doctor, they always swab your skin with alcohol, but when they do it to?

Question

my dog, they just shove the needle in without doing anything. I had a dog get infected once that way and it took weeks of treatment for him to get over it.

Answer 1

The dog's skin isn't exposed, so, most likely, the alcohol would be absorbed by the fur before it even made it to the skin; therefore, the skin would never get disinfected.  It would be wasted effort, and vets are lazy :P. (jk)

Answer 2

I think it probably has to do with the fur getting in the way. if a dog gets anything heavy like surgery, they shave and use antiseptics. They  should at least put on an antibiotic cream after the shot though.

Answer 3

To prevent what happened to your Dog. The alcohol cleans the skin surrounding where the needle would go and prevents infevtions.
