I don't think that the wounds you are describing are caused by chiggers. Fleas are still a possibility, I have found that products containing Fipronil do not work very well for flea prevention. I would also be concerned about mites, bacterial or fungal skin infection, or even cancer. I think it is time for Icis to see a vet so that she can get a diagnosis and some comfort. Benadryl will only help with itching if it is caused by an allergic reaction from histamine release, which does not seem the case. Dish detergent baths can be very irritating and drying to the skin, I would recommend a hydrating dog shampoo instead. I rarely use epsom salt baths for skin problems in dogs for similar reasons, it is much better used when there is swelling in the paws.
