Hello & welcome, I am Dr. B, a licensed veterinarian and I would like to help you with your wee one today.

In regards ***** ***** question, their choice of increasing the dose is not ideal. We do sometimes have to use high doses of certain in multi-drug resistant bacterial infections but your vet would have made you aware of this being the case and would have had another test done (called an MIC, which looks at whether the bacteria responded to any antibiotic at a higher dose).

So, if they didn't tell you this is multi-drug resistant (MDR) and if they didn't check an MIC; then we'd need to ring them and ask them to review the culture's sensitivity results. This is because the lab that tested this sample would have checked 6-12 other antibiotics to see if the bacteria was sensitive to anything else. And that is what we usually use in standard cases to choose our antibiotics. So those results would have told them the Noroclav won't help but also should have told them what would. So, that needs to be doubled checked so that a more appropriate antibiotic can be used. And if this was one of those uncommon MDR bacteria, then an MIC test should be checked on all the antibiotics by the lab to tell you which at a high dose may be needed.

All the best,

Dr. B.
