My puppy has non-red welts under fur. Is it an allergic reaction?

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 your dog is lethargic, take her to the vet in order to get an antihistamine injection.

This sounds like your dog has an allergic reaction to possibly an insect or spider bite or allergen. As long as your dog has no problems breathing or does not appear ill, you can wait it out. Should your dog have breathing problems or appear ill, vomits or the welts do not go away within 12 hours, you should take Romeo to your veterinarian or a petER for an exam, an antihistamine and/or a steroid injection.

These do indeed look like part of an allergic reaction (wheals/hives) and generally settle down after 12-24hours. Monitor closely for any internal complications such as vomiting, diarhhea, panting or weakness from an increased heart rate which may require hospitalisation and intravenous fluid drip. It can be difficult to identify the original trigger allergy bloods and a hydrolyzed diet such as royal canin anallergenic should be considered if recurring often

This is probably an allergic reaction to the shampoo, this reaction should resolve without treatment within a few hours, if it doesn't- take her to the vet in order to get an anti histamine injection.

Hello there. It sure looks like Wookie has some hives! He must be having an allergic reaction to something. I highly doubt it is food related. Food allergies are actually quite uncommon in dogs. It is more likely to be something in the environment or he got stung by an insect. I would recommend you give him some Benadryl (diphenhydramine). NOT the non-drowsy kind. He is a big dog so he can have 3 capsules/tablets. Hide them in a small piece of hotdog or cheese or something he likes to eat. I know it sounds like a lot of medicine but dogs take a high dose as they metabolize it much faster than we do. It may make him sleepy but it usually doesn't. If the hives are not gone in the morning or if you notice him have any trouble breathing, you need to take him to the vet right away. I hope this helps. Best wishes to you and Wookie! Dr. Amber
