Sounds like a bladder infection that, while responsive to Clavamox initially, remains and is persistent. When we see this, then we must move to a culture and sensitivity check. This helps the veterinarian determine the exact cause of the infection and which exact antibiotic to use. The antibiotic may need to be used for a long time to clear a persistent infection.
Work with your veterinarian to get this special test done and highly specific treatments.
Hello,
In addition to Dr. Humphies comments, with which I agree, I wanted to mention that the majority of urinary tract infections in dogs are due to gram negative bacteria which respond best in general to antibiotics specifically geared to kill gram negative bacteria.
Baytril and Orbax are both the same antibiotic. The difference is that Baytril is given twice daily and Orbax is given once daily. Both are specific for gram negative bacteria and in most cases are effective to clear up urinary tract infections.
Clavamox is an antibiotic effective against gram positive bacteria like Staph, often responsible for skin infections.
I agree that having your vet send in the urine for a culture and sensitivity is wise as this will tell the the exact bacteria(s) responsible and indicate the specific antibiotics, best to clear this up.
Thank you,
Dr. Carol Osborne, DVM.
