Hello John and Sue,
I am sorry to hear you are worried about Kallie. My name is Rebecca. I am a veterinarian and will do my best to help.
When a dog squats frequently but little or no urine comes out, it could be a bladder infection, or UTI. It is possible that a week's worth of antibiotics was not enough, and now the old infection has come back, or else she has a new infection.
When a dog has a bladder infection, the lining of the bladder is swollen, and it feels like it is full, even when there is little or no urine inside.
Another possible explanation is that she has a bladder stone. I would do a urinalysis on a urine sample as soon as possible. If you can't get a urine sample to take to your vet, I would take her in and see if they can collect a sample. I would also consider an X ray to check for bladder stones.
This is not normal, and it should not be a forever problem. She may just need another course of antibitoics, with a follow up urinalysis to be sure the infection is clear before you are sure it is OK to stop the antibiotics.
Let me know if this is helpful and what other questions you have.
