Do not confuse the rattlesnake vaccine with anti venum serum. They are two different things. The vaccine is given to dogs is less than 20 bucks. It creates antibodies in the pooch for use if he is bitten. A yearly booster is recommended.
Then anti venom serum for dogs runs around 500 bucks a dose and in general a vet only gives one dose and sees if it is going to affect the bite. Rarely do they give more than one ,unlike humans where anti venom serum is very expensive..2000 dollars a dose and they might give you 10 or so depending on the severity of the bite.
Many people are alergic to anti venom serum and it can kill you before the snake bite does.
You can also have an unpleasant reaction to anti venom serum and break out in hives..sometimes days after you have taken it. Very serious and this can kill you as well.
If your dog is exposed to rattlers, see your vet about the vaccine...Jerry Burney
