The product is a solution especially made for the dog by the lab/pharmacy that the veterinary dermatologist is affiliated with. It is prepared with various ingredients according to exactly what the dog is allergic to. It is different for each dog.

See my post above (7/25 7:18am) for a detailed description of Intra Dermal Skin Testing,
btw: It can be given sublingually now versus sub q (injections).
The initial testing is expensive but the maintenance is not so bad. We only go to the dermatologist once a year. Only go to the regular vet for annual heartworm testing.
Also, talk to your vet about it, but I avoid vaccines for allergy dogs.
