Kitty Posted February 18, 2009 Share Posted February 18, 2009 A friend with a healthy labrador puppy in France has had a rabies test failure and so another test has had to be done. Why anyone know why this happens? What are the chances of failing again?I have done a search, assuming that the question will have been asked before, but can't seem to find the answer.

ViVienne Posted February 18, 2009 Share Posted February 18, 2009 our puppy has just had his rabies jabs and we are waiting for the results, there are 2 or 3 different jabs on the market and if one lot fails they can try the others. Our vet said it is very important to have the blood test 21 days after the jab because the antibodies are at their highest at that point and more likely to pass the test. I'm keeping my fingers crossed for our dog, although the results are late coming through, the vet will have to chase them up tomorrow and as we have to wait 6 months from the date of the test results we're cutting it a bit fine for the August hols. Good luck to your friends and their dog, hope it goes ok. Link to comment Share on other sites More sharing options...
Patf Posted February 18, 2009 Share Posted February 18, 2009 I don't know why this happens with some dogs, Cathy. Perhaps someone with professional knowledge can give an answer.Our two (at the time) border collies had the same rabies injection regime, but when it came to the blood test one was well over the required level of antibodies, and the other just scraped through.Perhaps it's something to do with an inherited partial immunity.

Bugsy Posted February 18, 2009 Share Posted February 18, 2009 The test results (blood) have to achieve an SNRAGE rating higher than 0.5 IU/ml to be acceptable.We've just had our boxers results back and he is OK with a 0.87 figure.It can, apparently happen that some animals need two injections before sufficient antibodies are produced.Hope this helps Cathy.

Martin963 Posted February 18, 2009 Share Posted February 18, 2009 When we had the two English cats vaccinated in 2000 our vet recommended giving two doses, as it was far cheaper than subsequently failing the test!Our French vet only gave one dose, but the French-born cat passed his test anyway.
