Topic: Antibiotics

Question:Can I give my 3month old kitten antibiotics for diarrhea just 3 days from receiving first vaccine? Thanks

Answer:There are only a few specific antibiotics that help diarrhea - most will make it worse. It would be ideal to consult with the veterinarian that gave the vaccine - they will know the kitten's history better: what dewormers the cat has been given, whether a fecal has been done, etc. to try to figure out why the kitten has diarrhea and what the best treatment might be.

Topic: Is this normal?

Question:My 14 week old toy yorkie got her parvo vaccination shots they said there would be side effects but I just wanna make sure my baby girl is gonna be ok.... at first she seemed fine but now she is breathing rapidly and panting like she is thirsty but it drinking. Is she gonna be ok? My husband says it will pass but being a mom I am worried...

Answer:She might be a little sore, achy and a little lethargic (mopey) - they can run a low grade temperature, usually just the day of the vaccine. Breathing rapidly can be due to a lot of things, but if she worsens, definitely have them recheck her. Things to look for: facial swelling, vomiting, hives, extreme lethargy - these many be signs of an allergic reaction and you would definitely want to have her checked if you see any of those.

Topic: Vaccine Reaction

Question:My dog got her rabies shot yesterday, 10 hours later she presented with a high fever, loss of bladder control and difficulty with balance (she behaved like she was drunk and is almost falling down) her head weaves back and forth and she flinches and jumps when we reach to pet her or when she gets to close to an object as if her depth perception is off. The vet said she had never heard of this reaction to a rabies vaccine and thought she ate something toxic, however, I know she has not been into anything. The symptoms lasted about 7 hours then she was better this morning. At 6:00 pm this evening the symptoms began again. What could be going on and what can I and should I do for her?

Answer:I would take her back to see your veterinarian - they can run blood tests to determine what is going on. They can also give her anti-inflammatories if it is secondary to the vaccine to kind of calm her immune system down. Record what she is doing on your phone if you can - a lot of the times when they get to the vet's office, they won't do what they are doing at home.

Topic: senior dog

Question:My pet Kayla she is a 59 pound dog 12 years old. I have read that a senior dog does not require shots every year. She is an inside dog that I walk every morning and evening. They say senior dogs can go every 3 to 5 years. What is your feelings on this?

Answer:Yes, if she has been reasonably well-vaccinated throughout her life, she can go 3 years between (most) vaccines (DHPP and Rabies). There are some exceptions - like Kennel cough, Influenza, leptospirosis, Lyme, etc. These are given based on her "lifestyle" and where you live. Discuss all of this with your veterinarian and see what vaccines are best for her.

Topic: canine spectra 9

Question:I gave my puppy his first dose of spectra 9 at 9 weeks. The packaging says to give every 2-3 weeks until 16 weeks of age... if i give a dose every 3 weeks, then his 3rd dose will be given when he is 15 weeks old. Do I need to give one more dose after this?

Answer:You can spread them out just a little longer - the interval we follow is 2-4 weeks - and that last vaccine should fall closer to 16 weeks. It is a good question because that last vaccine does need to be at or even a little beyond 16 weeks. As he is going through his vaccine series (and a couple weeks after the last vaccine) keep him away from "high-dog-traffic" areas like dog parks, anywhere lots of lots go to the bathroom. He doesn't have to come into contact with an actual dog, it's the ground that parvovirus can live in for years.

Topic: Vaccine reaction

Question:My 9 year old 12 lbs chihuahua became very lethargic minutes after being vaccinated for Lepto and Bordetella. She has also been throwing up the water I have been given in my attempt to keep her hydrated. I don't know if I should be withholding liquids and food or if I should attempt to give her Pedialyte. Could this vaccine cause kidney failure in such a short amount of time? I'm so concerned and I would like to know what to do to help her without ending up with a $2,000 vet bill. I'm currently unemployed. I thank you in advance!

Answer:It sounds like she is having an adverse reaction to the vaccine (not necessarily kidney failure - that's not a known side effect). Whoever administered the vaccine will almost always pay for treatment so call exactly whoever gave the vaccine and either they or the vaccine manufacturer will usually help with treatment. Treatment is usually easy and no where near $2000.

Topic: vaccination question

Question:I am wanting to vaccinate our new puppy with the 9-way vaccine and bordetella. I see that the 9-way protects against parainfluenza and I also noticed that the bordatella protects against parainfluenza... is it safe to give them both at the same time since they both protect against parainfluenza?

Answer:That is good question - the puppy definitely doesn't need 2 dosages of parainfluenza at once, so definitely don't give them both at the same time.

Topic: Flea vaccine

Question:I think my dog is having an allergic reaction to the vaccine that was administer to him. He eyes are dilated, he breathing a liitle hard. He doesnt want to move he's tail is still wagging but im afraid the dosage was to much for him since he only weighs 5 pounds . Please help me

Answer:Please contact whoever gave him the vaccine - different vaccines have varying potential for allergic reactions and side effects - you calling this a "flea vaccine" has me a little confused as well, so whoever administered it will know your dog better and what "vaccine" was actually given to him and how much to worry about it.

Topic: Reaction

Question:She appears to have the shakes & her body temp is cool

Answer:It is not uncommon to run a low grade temperature and get the shakes after a vaccine. It shouldn't be too bad though, so if she doesn't improve quickly or if she is really mopey/lethargic, you should have a veterinarian check her out.

Topic: 2 years old German Shepherd

Question: Hello I have a 2yr old male G.Sheperd o take him to the rabies vaccine they want to add the parvo booster shot but after one day he came walking adnormal so i take him to the vet he say i can't be the shots maybe something else but i'm too worry because after he came back home he start urinating red! Like blood and i call them they say that is normal but i don't tink so!!! so they prescrive him amoxixiline 500mlg 2 tables twise a day and novox 75mlg a day before i contact the vet again because he still pee red after i removed novox please tell me what can i do? I'm so worried

Answer:I have never known a vaccine to cause a dog to urinate blood unless he is having some sort of very rare reaction - the two things are more than likely unrelated. Urinating blood is never normal. If it hasn't improved with the antibiotics they need to recheck him and probably take some x-rays looking for stones, etc. They will need another urine sample so try to keep him from urinating before he gets there.

Topic: Spayed and shot reaction

Question:My dog was spayed and had the parvo and rabies shots she is 2 yrs old. She has had a fever and chills for 2 days she is drinking alittle water and has at alittle too she isa small dog 8.4 lbs. Is there anytging i can do for her?

Answer:BEst to take her to vet if signs persist or worsen. In future you should know that immunity to core parvo/distemper vaccinations lasts for YEARS TO LIFE OF ANIMAL, and that further vaccination for these are likely not necessary. Also try not to allow vets to vaccinate your pet at times of physical, emotional or surgical stress, especially in toy breed like this. If signs still persist in coming weeks, you may want to consult with homeopathic vet trained in detoxing pet like this www.doctordym.com

Topic: Treatment for seizures after a vaccine

Question:Hi Dr. Dym and Vet Team, My dog Maya, a 12 lb white Maltese Mix Rescue had her last Distemper vaccine when she was 8 years old. Less than 12 hours later, my incredibly healthy, loving and happy dog had a seizure and almost died. She was so sick for almost 7 days to the point where she couldn't even walk. I worked with a herbalist and we got her through it. We put her on herbs, cottage cheese, benedryl etc. However, many things happened after that. Her allergies increased so much so that she is not only allergic to pollens, trees and most grasses, her food sensitivities soared and her diet is very limited. She now has random seizures once or twice per year and I'm not sure how to help her. I've tried everything. As soon as it starts I shove raw honey in her mouth and it stops faster. I'm not sure if she is now hypoglycemic as a result as well so I make sure is fed every 3.5 hours. I'm never late. She eats organic, free range eggs, turkey, boar with spinach and green squash. If I feed her anything else she starts itching uncontrollably. She also gets yeast infections if she eats anything else that is carby - like lentils, carrots, etc. She has dog clothes on right now as it keeps her from itching so bad. If not, she cries and bleeds. I put her on rounds of probiotics and digestive enzymes - one month on/one month off to keep her system as strong as possible. She gets fish oil almost daily. She's sensitive to coconut so I cannot give her that as well. Her blood work is good. Her liver enzymes are just slightly high but that may be due to her eating prior to the blood test. The vet says the blood work is normal. I can't let her have an empty stomach as I'm afraid of a seizure. That's the quick summary. My question is - She is now 11. It's been 3 years since the vaccine. Is it possible that she has toxins from that vaccine in her system still that could be causing the seizures? If so, how can I detox her? Is there a way for me to test if she is hypoglycemic for sure? Any other suggestions as to how I can heal her would be so appreciated. She is just the best dog, I love her so much - she's my whole heart. Any thoughts are so welcome. Thank you! ChrisAnn

Answer:The adverse effects from the vaccine should not be causing her a problem 3 years later (that we know of). It is very rare for an adult dog to have issues with hypoglycemia but it is really easy to check for - in fact, it sounds like she has had a good bit of blood work done and glucose is on almost every panel we run. Getting a fasting blood sample might be a good idea on her to be sure - you could also recheck her liver enzymes with a fasting sample. Allergies are really frustrating but there are many new medications out now that make them more comfortable that have less side effects than some of our older medications. Work with your veterinarian to find the one(s) that might work best for her.

Topic: Is this normal

Question:My dog has had vaccines in past with no problems. This time he thru up 4 times and today he is sleeping a lot but no longer puking. What should I do

Answer:At a minimum you need to call and alert the veterinary office where he got the vaccines - they will want to know that and note it in his records and maybe spread out his vaccines next year or recommend a longer interval for him, etc. If he still feels bad, it would be ideal for them to check him out, take his temp, etc.

Topic: Severe fatigue

Question:I got Cole 3 vaccines this morning, DAP-pv Vac-3yr, Leptospira 4serovar 1yr and Borrelia 3wk. Cole is a very active 2yr old APBT and around 3 hours after shots barely moves and when he does whimpers. I have had to hand feed him and give small water bowl. Shots where giving in both back legs and one front leg.

Answer:It is not uncommon to run a low grade temperature after vaccines but it should not be "severe" and he should not "barely move" so you probably want to have him rechecked as soon as you can, preferably where he got the vaccine. They can give him medication to calm down his immune system and make him feel a lot better quickly. You will need to spread out his vaccines in the future - by at least 2 weeks is what an internal medicine specialist said at the last conference I went to (for dogs that seem sensitive to multiple vaccines given on the same day).

Topic: Vaccines

Question:I took my cat to the mobile better yesterday for his shot. Now all he does is lay around and sleep. He was healthy and active before he got the shot. I thought he was having a reaction to the shot but now I'm worried it's killing him. He's 5 years old and just lays around sleeping He's drinking some water and he ate some last night. But he hasn't eaten today. Is there anything I can do? I don't want to lose him because of a shot. Please let me know what I can do. Thank you

Answer:You should contact the company that administered the vaccine - for a lot of reasons : they need to note it in his chart, they will often pay for treatment if he needs it and it is related to the vaccine, they will know if other cats are having problems with that lot # of vaccines, etc. A little lethargy can be normal for about 24 hours after a vaccine but if you are "worried it's killing him", you should really have him rechecked immediately.
