Good morning,Customer Thank you so much for your question this morning and I hope I can be of some help to you!
To get right to it, based on your description, I would be VERY concerned that your dog has a UTI, for these reasons:
1) It sounds like she currently has a stone in her bladder, which makes dogs extremely prone to secondary UTI's
2) She is going potty very frequently
3) Her urine has a strange odor
It is very easy to screen urine for an infection, so it would be well worth it in her case to bring in a sample to your vet and have it screened for possible infection. Perhaps she doesn't have an infection, but again it's very easy to check for and would be a good next step.
Here is some information on bladder stones and infections:
The article mentions struvite stones. Dogs usually have one of two types of stones, struvite or calcium oxalate, which are treated differently. If your dog is on SO I suspect her stone might be struvite. These stones are very related to infection and often these dogs need to be checked for infection regularly.
I hope this information helps--let me know if you have more questions!
Dr. Marcia :)
