Hi Sue--
I'm rushing out the door. But yes, it's okay to give both medicines.
The TCC and bladder infections go hand in hand. I've read some people on the board have their pups on a constant low level dosage of antibiotics.
Annie has been lucky--she hasn't had any infections until just a couple of weeks ago and then it was a doozy!!!!! One course of antibiotics seemed to clear it up, but it was back again after two weeks.
The second time I was more on the lookout so we put her back on the antibiotics right away. They clear up the symptoms for us within three days --thank goodness!!!
Good luck
Marty
