My dog got a lepto, lime, and bordetella shot Thurs night. We come home today, he is lame and lethargic. How long will his reaction last? Should I rush him back to vet?

I'm so sorry that Buddy isn't feeling well after his vaccinations. I would certainly recommend calling your vet to discuss his side effects and decide if he needs to be seen or not. When we give a vaccination, the stimulation of the immune system can cause an inflammatory process that can result in some joint or muscle soreness. Some dogs will also be lethargic and can run a fever. These side effects will generally resolve within 1-2 days, but sometimes we will recommend giving medications to make the pets feel better in the meantime, so I would recommend discussing it with your vet. For the future, I generally will only give one vaccination at a time to dogs that have the potential to have vaccine reactions to minimize the potential for this to happen again. Good luck! I hope that was helpful and that Buddy feels better soon. Thanks for using Petco Pet Education Center, formerly Petcoach.
