Thank you all for your support. The results are in and Winnie definately has a very bad case of bladder infection. This does nto rule of incontence however, but we will see after her dose of antibiotics. Being a lab I think there aren't any diapers big enough so I will just keep washing the floor and washing her fur.
Her poor bottom was all raw mostly due from the heat and laying in her own urine...I feel so helpless right now. I feel for her...the vet shaved her so that it may prevent the urine from smelling..anyway I hope she will recover soon. She's is a remarkable dog...smelly as all h***
