My adult dog's vaccine history is unknown. Primary shots or boosters?

Updated On September 23rd, 2025

Pet's info: Dog | Pit Bull Terrier | Female | unspayed | 68 lbs

My family was given a dog which is possibly 8 years of age. This dog MAY have been vaccinated before but we are not for sure. The person who gave us the dog is not available to give us the dogs health information. Should I go ahead and give the dog a primary vaccination (2 doses, 2-3 weeks apart. Which is the recommended time frame for the particular vaccine that I give myself.) OR should I just resume vaccination booster annually? I will be using Solo-Jec 6 dog vaccine. Thank you.

Do not vaccinate yourself, I never recommend it. Owners often give the vaccine wrong, rendering it ineffective. In addition, places that sell vaccines often store them wrong, making the vaccine ineffective. I cannot tell you how many cases of Parvo and distemper I have seen in dogs who have been vaccinated at home. In addition, Cali need rabies, it's required by law and can only be given by a vet. I strongly urge you to have her vaccines done by a vet, her heath is too important.

I have recently adopted a female boxer from a ad situation, she is perfectly healthy but has never had any vaccines, she is a year old. Would it be ok for me to give her a 5 way shot myself as I cannot afford for a vet to do it. If so what kind woul
Hi and thanks for using Boop by Petco. If at all possible you would want to take Chevy to a veterinarian so they can discuss the best vaccines and vaccination schedule for your area. She also needs a rabies shot and that has to be given by a licensed veterinarian or licensed technician. Vaccines given by your vet are tracked, handled and stored properly, and the manufacturer will stand behind the product if there is an adverse reaction or event. The problem with just buying the vaccine from a feed store or catalog raises the questions of shipping, storage conditions, quality of the product, and lack of back up from the manufacturer if something did happen. Vaccinations are vitally important to Chevy's health so they should be done by a professional so you can have piece of mind. I wish you the best.

I have 8 puppies and want to give the vaccinations by myself at home. I do not want to take the risk of taking them to a vet. Clinic , it could sress them and may acwuire diseases.
I do not recommend this. It's your choice, but their health is too important to take risks. Puppies usually are just fine at a clinic, people get their vaccines done all the time with no issues. I have found owners who try to give them at home often do it wrong, rendering the vaccine ineffective. In addition, places that sell vaccines to owners sometimes store the vaccines improperly. leaving them ineffective. I cannot tell you how many dogs I've seen get parvo and distemper who have been vaccinated at home by their owners. It is your choice, but I strongly urge you against it.

My dog hasn't undergone any vaccine. Where do I go? We haven't been into any veterinary clinic. Can I get her vaccinated in our town hospital? Pr there is really a need to go to veterinary. Really dont know what to do since its my first time to adopt
Primo will need to go to a veterinary clinic. There, a veterinarian can perform a complete physical exam to confirm good health before vaccination. Core vaccines include distemper/parvo combination and rabies vaccines. She will need 3 combination vaccines spaced 3-4 weeks apart. A rabies vaccine can be given now and repeated next year at this time. She should also be dewormed and tested for heartworm then placed on the appropriate monthly preventatives against fleas, ticks, heartworm and intestinal parasites.

So I have been an awful dog mom! I have had Buster since he was 10 weeks old and he has never had any vaccines except for his Rabies shot. He is now 3 years old. I would like to administer the shots myself. What shots does he need? And am I able to a
Good on you for wanting to get Buster's vaccines! While you can get the vaccines he needs from a tractor supply store, I never recommend it. Tractor supply stores are notorious for handling and storing vaccines improperly, and I have colleagues with numerous stories of dogs coming down with parvo and distemper who had been vaccinated with vaccines from stores. It's too much of a risk, and if he did come down with something serious like parvo, it would cost you so much more to treat than the cost of having a vet give the vaccine. In addition, diseases like parvo and distemper have no cure, and are very often fatal. It's best to take him into your vet to get the DHPPi combination vaccine (distemper, hepatitis, parvo, parainfluenza). I hope this helps!

My adult dogs have a 5 in 1 vaccine (DA2P + Parvovirus) once or twice. Can these protect my adult dogs from Parvo?
Hi and thanks for using Boop by Petco! Good question. I always advise that your veterinarian administer vaccines and not the owners. Veterinarians are knowledgeable in the diseases of your area and can advise which vaccines they would like to give your pets. The vaccines are manufactured by known sources and are guaranteed from the manufacturer. If you give your own vaccines, you don't really know who made them, how they were shipped, what temperature they sat it, and if something happens they typically won't guarantee anything if your dog gets sick. If the vaccines are modified live vaccines, your adult dogs only need one shot which will last for one year. If the vaccines are killed, they will need one shot and then a booster shot in 3-4 weeks, and then one year later. No vaccine is 100% effective but most adult dogs don't get Parvo as long as they have been vaccinated for it. Good luck

I have a puppy that is due for a a 5-1 vaccine shot. Last time the puppy received the shot from the breeder it had an allergic reaction hives and swelling. I gave the puppy benedryl and it helped a lot but the hives were still present and swelling. I
I never recommend giving vaccines at home. First off, vets and places like boarding facilities typically do not recognize vaccines given at home, so Jasper would be considered unvaccinated. Places that sell vaccines such at Tractor Supply often store the vaccines wrong, rendering them ineffective. In addition, owners can and do give them wrong. I can't tell you how many cases I've seen of dogs coming down with Parvo and distemper who have been vaccinated at home. Take him into the vet to get it done correctly. Plus, by law he needs rabies, and that can only be given by a vet. I hope this helps.

i just recently adopted my dog and she’s about a year old. she never got her vaccines so i was wondering if i get them now , if it would hurt her or be bad to get them now ?
No - it will not hurt her and I would definitely recommend getting her vaccinated! There are many dogs in shelters who get their vaccines as adults. Some core vaccines like the DAP combo might require a booster while others like rabies don’t.

I have a pitbull/bull mastiv/boxer mix he was born on mother's day 2017. I got him as soon as he was ready and he has already had his first shot when I got him. It's now been a while and I wanted to know do I just continue with the second shot as n
Since Bailey is older than 16 weeks old, he should just need a booster vaccine now, and then one more in 3 weeks. After that, he'll be good for a year :) He should also have a rabies vaccine. I would recommend having the shots given by a veterinarian, if you can. The ones purchased over the counter for home administration are often not effective, in my experience. You also won't be able to get a vaccination certificate to prove that he's been vaccinated unless the shots are administered by a vet.

I adopted a dog ladt month, I had the rabies done but I don't know if she received her regular shots. The person I got her from never got back with me. His sister said he gave her the 5 in 1 from a feed store, but not when. I want records so that if
I would not rely upon this person having given the vaccines properly nor that the feed store kept the so-called cooling chain, ie that the vaccine did not get warm somewhere along the way and became useless. I suggest you start from the beginning. Take your dog to your vet for a basic exam to make sure she is healthy, and have her vaccinated as per recommendation of your vet. Also discuss having her spayed if you do not want to breed her.

I gave my 3 month old puppy her first puppy shot but I don't think it all went in what should I do?
If you don't think all of the vaccine went it, she will have to have another one in a week. I would recommend very strongly you take Lucy into the vet to have her vaccines done. The vet will be sure to get all of it in, plus you know for sure the vaccines are stored correctly at a vet's office. I have many colleagues who have seen cases of parvo and distemper in dogs who were vaccinated at home. Places that sell OTC vaccines often store them inappropriately, rendering them ineffective. In addition, by law, puppies need to be vaccinated for rabies by four months of age, which can only be done by a vet. You would need to take her for that anyway, so get the vaccines done there as well. Your puppy's health is too important to risk. I hope this helps.
