I hate t hear Max is having this issue. Most puppies with Giardia are fine to vaccinate as long as they are not lethargic, not eating well, vomiting or have severe diarrhea. Mild, non-bloody loose stool in a puppy who is active and eating well can generally be vaccinated (though you may space them out to be more safe). Also, giardia testing needs to be done 4-6 weeks after treatment to be sure the parasite is gone. Some pets will need a combination of medication to kill the parasite. Make sure to check with Max's vet to make sure it is ok to vaccinate him and to make sure Max is getting the correct medication. I hope this helps and please feel free to post any additional questions.
