Senior Guinea Pig
Allergies are definitely a possibility but I would speak to the vet, they may want to try a different antibiotic first. I do have a pig that is sneezing at the moment and her chest is also clear and I think it is related to the hay. I think some harvests affect them more. You could ask your vet about an anti-histamine? I believe they can have Children's Piriton but you would need your vet to agree.
