Question about crate training my pit bull

We just adopted a 8 week old pit bull Catahoula mix puppy and we have her for 2 weeks now she pees in the house about every 30 to 45 minutes even after going outside to pee. we have 2 other dogs in the house and they play a lot together. we are crate training her and she has even had accidents in her crate. any suggestions would be great.

 

Answer from Dr. Gaylord Brown:
TThis is unusual. She may have a urinary tract anomaly called an ectopic ureter. Consult your veterinarian about tests to rule out this problem.
