Rocco may be sore at the vaccination site. Do you know did they give the booster vaccine in that back left leg? With animals we give vaccinations under the skin and not in the muscle so it is pretty rare for them to be sore afterwards but it is possible. Some older vets still vaccinate in the muscle in which case they have a higher chance of being sore. Do you know if it was given in the muscle? I suggest you ice the area where the vaccine was given for 5 minutes 2-3 times per day for the next 2 days and let him rest. You can also give BUFFERED aspirin for 2 days ONLY to see if that helps. If he is not improved in two days then get him back tot he vet for a follow-up. You did not mention his weight for me to be able to give you an aspirin dose. If you can't figure it out from this dosing information sheet you are welcome to post again for more help or you can opt for a private consult and we can chat back and forth.
