My dog has vaccine reaction: what to do for swelling, blisters, hard spots?

Your dog should get an antihistamine before the vaccination. You should ask your vet about giving him a diphenhydramine , or chlorpheniramine injection about an hour before getting the vaccination. This should avoid the reaction or at least reduce the impact. Your veterinarian should have these injectables available.

If the Benadryl was effective, I would have expected to see a reduction in the swelling by now. Sometimes allergic reactions require stronger drugs to treat such a steroids, and it sounds like this may be the cause for Moose. Because the swelling hasn't reduced and the reaction appears to be progressing, it's time to see a vet immediately. Please take him into an ER vet clinic if your regular vet is closed; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

It is only dangerous if the swelling is causing her to have difficulty breathing. Getting her to a vet is the best option but if you want to try something at home you can give Benadryl by mouth at 1mg per pound of body weight (example, if she is 25 pounds, she would get 25 mg). Always let the vet know when she is vaccinated in the future that she had a previous reaction.

A swollen face, swollen lips, red eyes, severe itching or difficulty breathing may all be symptoms of a vaccine reaction. An antihistamine, such as diphenhydramine (Benadryl), can be given but only under the advice of your veterinary. Legally, we are prohibited from recommending you medicate her in the absence of a physical exam and a VPCR (veterinarian-patient-client relationship). If her symptoms persist or worsen, have her examined by your veterinarian or at the nearest veterinary ER.

Hello and thank you very much for your question. What you were most likely experiencing is an injection site reaction. D’s can sometimes go away within 24 to 48 hours for these can stay for months. Sometimes these reactions can also be painful and elicit other immune responses such as difficulty breathing, etc. My best advice is to contact the veterinary clinic that administered the injections and tell them what you are experiencing. What most likely will happen is that they may want to re-examine your animal and possibly give you some topical or oral or injectable medication to offset the inflammation. Generally, these appointments do not cost anything and be makers of the vaccine take care of the costs associated. But this all depends on the veterinarian and the clinic involved. So I Urge you to call the veterinary clinic and schedule an appointment as soon as possible to get this lump checked out. We really appreciate you using our service. I hope I have helped.

You can give her an antihistamine tablet. This is probably an allergic reaction due to an insect bite or a plant outside. those reactions tend to resolve within 48 hours without treatment. if the swelling becomes too large or if Arturo is lethargic, take her to the vet in order to get an antihistamine injection.

Thank you for submitting your question regarding Bella. I try to avoid chronic high doses of steroids in dogs whenever possible as there are side effects internally and externally. However, an injection to control a reaction is not something that concerns me if she is not taking other medications. Steroids can interfere with certain drugs. If her veterinarian deams it necessary after seeing her, then I would go ahead and have it administered. Great question!
