Although an antihistamine may help slow down the reaction, if your dog has any of these signs it is very important to have him or her checked out as soon as possible. Cats rarely have this type of reaction, but it is possible and should be examined if noticed. Overall, these reactions occur very infrequently. The diseases the vaccines help prevent are a much more serious threat to your pets' health than the potential vaccine reaction. If you have any concerns or if your pet has a 'family' history of vaccine reactions, please discuss the issues with your veterinarian.
All pets benefit from a thorough physical exam, regardless of health.
Many illnesses are very subtle in the early stages, and a physical exam by a veterinarian may reveal an illness that is not yet causing major problems. As in people, diseases are usually easier to treat and cure in the early stages than later. Cushing's Disease is more properly known as Hyperadrenocorticism. This is a condition where the adrenal gland's cortex overproduces one or more different cortisone-type steroids. Although it can affect any dog, some breeds of dogs are especially susceptible to developing Cushing's disease.
