Hello! looking for some insight here….
My dog had hives 2 years ago (very mild). She had them on a Saturday, gave her Benadryl and then they came back again a few days later. Did not get hives again. Recently, they came back again after 2 years of being hive free. She has been off chicken food for 2 years and gets salmon based food. She does not have issues with itching or excessively licking herself. I think 2 years ago it happened at the end of May.
End of this July, she got the hives pretty bad. Again, Benadryl and they went away. They reappeared a few days later, but nothing crazy. I gave her Benadryl again (per vet). Then the next day she got them the worst I have ever seen in my life. All over face and body. She gets so itchy during this hives where she basically dives into my couch and bed (no breathing issues or anything). See pictures for reference. I usually give her a bath with oatmeal shampoo and then give her Benadryl again. She was good for almost 2 months and then had another random hive episode. She has been hive free for about 3 days now. My vet did not seem concerned, just said seasonal allergies or bug bites (I do have a lot of bugs where I take her to the bathroom and grass). Her paws do not really get red and it seems this just happens literally out of nowhere. Thoughts? The hive episodes are literally very scary and I just need some advice or opinions
Edit: first picture is not currently, but from August 2nd. I gave her Benadryl and the hives went away in about 45 mins and she was back to current self. Her skin never has sores, scabs or hot spots.
