Dog threw up, swollen face after allergy shot. Is it anaphylaxis?

It's probably an allergic reaction to either an insect, something in the environment or something he ingested. if it seems to just be getting worse you need to take him to the vet right now in order to get a steroid injection.

These are signs of an acute allergic reaction and immediate check up would be required to confirm this clinical suspicion and treat appropriately. Steroids and antihistaminic drugs are very likely to be needed.

Swelling of the face and mouth/facial swelling are often initial symptoms of an anaphylactic/allergic reaction. These reactions can occur in dogs after vaccines, after exposure to a food or substance they are allergic to, or after a bite from an insect. As it is impossible to predict whether an anaphylactic reaction will remain localized or progress to trouble breathing, which can be life threatening, it is safest to contact a 24 hour vet for Bella at this time to have her seen. The ER may recommend a treatment plan including anti-histamines, corticosteroids +/- epinephrine and montitoring until the selling has gone down. They will also likely recommend an at home dose for Benadryl after establishing a valid patient/client relationship if this should occur again as it is uncertain at this point what Bella is allergic to. Wishing Bella a quick recovery!

Hello, thank you for your question bout Sophie. Based on the symptoms you describe and the photos you’ve provided I believe Sophie is having an allergic reaction. Reactions can become quite severe and can cause breathing problems. Please contact or have her seen by a veterinarian as soon as possible so that they can treat the reaction and prevent it from worsening. Good luck!

Oh no, this isn't good. At this point in time, you cannot treat this at home, Pepper needs to see a vet now. Please take her into an ER vet clinic; 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.

Hello and welcome to Petco Pet Education Center, formerly Petcoach. Allergic reactions after bug bites in dogs can result in a swollen face, and can also result in some gastritis (vomiting and diarrhea). It looks like the swelling is improving which is good. I would suggest a vet visit if you can for the vomiting and diarrhea, however if that isn't possible then I would suggest to feed a bland diet of boiled/boneless/skinless chicken breasts and boiled rice, in small frequent meals for the next couple days. This will heal up a mild gastritis. The swelling will take time to come down, so just monitor that it isn't getting worse. If the diarrhea continues or if it becomes very bloody (looks like jam) then you will need to figure out how to take him to a vet. Best of luck with Charlie!

Hi, and thanks for your question. This presentation is likely to be due to a gastritis due to dietary indiscretion. The ey seems normal as far as I can see from the pic. As a first approach, I would suggest to start feeding with a bland diet based on boiled chicken and rice in small portion every 6 hours for the following 48hours. Then gradually reintroduce the normal diet over 5 days. I would definitely recommend a veterinary check up if the signs persist or you notice diarrhoea, lethargy or inappetence.
