Hey! I recommend that you bring your dog back to her vet to get her checked out! A young puppy that is lethargic and vomiting will probably need to be hospitalized on IV fluids and anti-nausea medication. -Dr. Lindsay Butzer

Hey! Some animals are prone to seizures due to a variety of reasons that aren't always known! I personally have never experienced an animal having a seizure due to a vaccine! I would suggest that you talk to your cat's vet about this. They might recommend doing some diagnostics and starting your cat on a seizure medication to help prevent another one from happening! -Dr. Lindsay Butzer

Hey! Sometimes vaccines will make puppies a little lethargic for a day or so but if it persists, I would suggest bringing her back to the vet especially if she isn't eating, is vomiting, or is having diarrhea. -Dr. Lindsay Butzer

HEY! Some cats stop eating after getting this injection. Please ask your vet to examine the cat, which they should do complementary if you did the vaccine at that vet. Your cat may benefit from a steroid injection! This is what helps my cats after they get vaccine reactions. I hope this helped!

Hey! If your pet is having a vaccine reaction they need a steroid injection and Benadryl injection. Benadryl pill could work 1mg per lb, but steroid is the best! Please go to your local vet for this. I hope this helped Dr. Lindsay Butzer! Please check out my YouTube channel here! https://www.youtube.com/channel/UCBvlURdNKSJ2oRbzUB1_JQw

HEY! There are many medications for seizures. You need to speak to your local veterinarian or possibly a neurologist however your local vet should be able to handle seizures just fine. They may start out weak with Gabapentin and Keppra then the strongest medication for seziure control is Phenobarbital. Please talk to your vet. I hope his helped! Dr. Lindsay Butzer

Hey! I would first suggest going into your veterinarian and letting them know that she did not do well after the bordatella intranasal vaccine and that she needs her shots spaced apart. If you can't go in tomorrow try giving your boxer puppy some Benadryl 1mg per pound and see if this helps with an allergic reaction. If she is eating and drinking that is a good sign and she may just need to ride out the lethargy but keep monitoring her. I hope this helps. Dr. Lindsay Butzer

Yes. Please go to the veterinarian for a steroid injection to fight the allergic reaction happening! The steroid injection is what he needs to get swelling down fast. I hope this helped! Dr. Lindsay Butzer

It is probably coincidence, but really impossible to guess. Divide up all of his vaccines in the future - waiting at least 2 weeks in between and talk to your veterinarian about which ones are absolutely mandatory for him based on his lifestyle.

Your question did not come through. Feel free to submit another question if you still need help.

No - that is not a normal reaction. I would have your veterinarian recheck him.

Good question - the research is ongoing. Most vaccine companies will say they continue to need it every ~3 years for life.

Have your veterinarian recheck her if it continues. Even if she is better by now, let them know, so they will separate the vaccines the next time she needs them and not give 4 at one time to such a small dog.

If it doesn't continue, she isn't lethargic when you get home, she has no facial swelling, etc. I would be more suspicious of motion sickness in the car than a vaccine reaction.

No, this is not a common side effect. I would have your veterinarian recheck her and aspirate that lymph node if it is still enlarged.
