We have a 10 week old puppy that has an e-coli uti infection and bladder stones. Has anyone had experience with a puppy this young having stones? Is there anything we can do other than surgery to dissolve the stones? We purchased our pup from a breeder two weeks ago and noticed blood in the urine within four days. The vet is 100% sure the dog had the infection and stones prior to us receiving the dog. The vet did a culture on the urine and found the e-coli infection. Also, ultrasound confirmed stones that did not appear on the xray. Because of this the vet thinks they are urate stones.
