My dog vomited after oral Bordetella vaccine. Is it still effective?

Updated on September 23rd, 2025

If a dog (daschund) vomits on the car ride home after receiving the oral Bordetella vaccine does he need to be vaccinated again?

No - this vaccine is absorbed through the mucosal tissue in the mouth, so it "works" as soon as it's given and comes into contact with her gums and the inside of her cheeks. Vomiting after the fact will not affect its efficacy at all.

I would be a little surprised since the Bordetella vaccine is a little less likely to cause a reaction, but technically it is possible. I'd recommend notifying your vet of the possible reaction. Watch for vomiting and facial swelling or hives, and ask if it would be okay to feed her a bland diet for the next few days to help with the diarrhea. They may want to give her an injection before she receives a Bordetella vaccine in the future.

Dog sneezed out bordetella vaccine. Is he protected from kennel cough?

Yes, the way this vaccination works is contact with the mucosa of the nose. Typically there is more than enough vaccine in the bordetella vial because many times it is sneezed out or runs out, so yes, he should be protected still.

My dog snorted out her nasal vaccine. Will it still work or hurt?

No, this is completely normal with intranasal vaccines. The entire volume doesn't need to stay inside her nose, it just needs to make contact with the nasal lining - most dogs immediately snort most of it back out. The vaccine will still be effective. Licking it will not hurt her at all.

Dog threw up antibiotic, then ate it. Is the dose still effective?

Because Pesci threw it up not long after taking it, yes it will still be effective. Antibiotics can cause upset stomachs, so I would give him his pills with some food such as boiled white meat chicken (no skin or bones), cheese, or peanut butter. I hope this helps.

Dog puked after dewormer. Is it still effective or needs redosing?

If your dog vomited more than an hour after the medication was given it is probably OK and in his system. However, if the dog vomited before an hour had passed then you will need to redose your dog with another round of dewormer. This medication is very safe and redosing should not cause a problem. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck

My puppy threw up after getting his shots. Does he need them again?

Poor Rocky. No, rocky does not need to get the vaccines again. The vaccines absorb through the mouth so him vomiting will not affect them. I would recommend talking with your veterinarian to see if they can help give rocky medications to decrease his car sickness! Hope that helps

My puppy got Bordetella. How long do vaccine-related coughs last?

The Bordatella vaccine is what we call "modified live" . This means that the actual virus is altered slightly to make it non-infectious, but still recognizable and stimulating to the immune system. If your dog is coughing, my suspicion is she contracted it based on exposure pre-vaccine. Generally this virus will run its' course within a month, but antibiotics can help prevent any secondary bacterial infections. A cough suppressant can also help keep her more comfortable.

Is twice-yearly Bordetella for kennel cough safe for my dog?

Actually it sounds like that grooming facility is very responsible. There are two types of bordetella vaccines, one is an injection of killed vaccine, the other is a live vaccine that is given orally. Bordetella vaccinations should be repeated every six months to a year. The live vaccine is much more effective. The bordetella vaccination given twice a year will not harm your dog and will ensure higher protective titres, and so protect your dog much more effectively from kennel cough.
