My dog got two initial canine flu shots. Does he still need a booster?

My dog accidentally got two initial canine influenza shots. Is this the same thing as getting an initial shot plus a booster shot? What's the different between the two shots?

Thank you for submitting your question regarding your dog. An initial influenza vaccine is given and then a booster vaccine is required 2-4 weeks later. They are the same vaccine, but given at this interval in order to properly stimulate the dog's immune system. So even though your dog accidentally received a second vaccine, a booster will still be required at the proper interval for full protection. I hope this information helps!
