Excessive urination

[bumzhabum]

We've had our basenji, Ninja, since he was 9 weeks old. He is 10 months now. Up until about 2-3 weeks ago he was generally potty trained. He started sneezing a lot over multiple days so we brought him to the vet. The vet determined that Ninja had a bacterial infection in his nose and prescribed an anti-inflammatory and an antibiotic. He mentioned that the anti-inflammatory would cause excessive peeing. Well, it did cause Ninja to drink and pee more than normal and he started to have accidents in the house and even soil his crate nightly. He was only on the meds for 5 days. Since then, the urination issues persisted. He is still having to go pee every 1-3 hours and wets his crate every night. He also drinks it. I plan on bringing him back to the vet this week but someone please help. Has anyone been through something like this? My previously house broken basenji has suddenly reverted back to a bladder control-less invalid dog… Oh and I have called the vet to voice my concerns but he said it may still be the meds...but really, 2 weeks later??
