CA­NINE ADE­N­OVIRUS

EQUUS - - Barn Dogs -

Ca­nine ade­n­ovirus is re­spon­si­ble for two dis­tinct ill­nesses in dogs: Type 1 causes in­fec­tious ca­nine hep­ati­tis. Dogs typ­i­cally pick up this virus through con­tact with another dog’s urine. As the virus spreads through the blood­stream and de­stroys cells through­out the body, the dog’s liver be­comes stressed as it at­tempts to clear the re­sult­ing cel­lu­lar de­bris. Signs of ca­nine hep­ati­tis in­clude vom­it­ing, high fever and jaun­dice. It is usu­ally not fa­tal but it can be if the dog’s liver is se­verely dam­aged. Ca­nine ade­n­ovirus Type 2 causes res­pi­ra­tory ill­ness and is one of the agents as­so­ci­ated with “ken­nel cough.” This form of the virus, of­ten spread by in­fected, cough­ing dogs in en­closed ar­eas, causes a fever, nasal dis­charge and a char­ac­ter­is­tic dry, hack­ing cough. Treat­ment is sup­port­ive care and rest. Most dogs re­cover quickly, but the virus can also lead to pneu­mo­nia.

► Rec­om­men­da­tions: Vac­ci­nate pup­pies against ade­n­ovirus start­ing at 6 weeks and then again ev­ery three or four weeks un­til they are 14 or 16 weeks of age. A booster is needed no longer than one year after the ini­tial se­ries and then ev­ery three years there­after. Adult dogs can be vac­ci­nated with a sin­gle in­jec­tion and again ev­ery three years.
