Sadie is my much loved poodle/border collie mix (and prob other things). She is 5 years old and has had the occasional "accident" but usualy only after vigorous exercise. She has now developed full blown incontinence. Vet has done lots of tests, but nothing major has shown up. She has been on anti biotics for 5 weeks and hormones for two but neither has done any good. She is also on Hills u/d special food because she had some crystals in her urine - which now seem to be disappearing. She is drinking a lot, and wets herself when asleep or relaxed and doesn't know she is doing it - when she realises she tries to clean herself. Does anyone have any thoughts or advice?
