I took my dog to the vet like 2 weeks ago for a vaccine (rabies). Yesterday I felt a small mass just before his knee. Could this be caused by the vaccine or should I be worried?. I know I have to take him to the vet. I just need to save some money. The mass is soft and it does not causes him any pain. What could it be?

I doubt this is from the vaccination.Please get the dog to the vet ASAP. Could be something simple as a fatty tumor, but also could be something very serious as Osteosarcoma ( bone cancer ). Good luck and I hope it is the first that I have mentioned.

No, it would not be caused by the vaccine. The lump that you are feeling could be many things...take him to the vet as soon as you possibly can.
