We have a 17 month female Cockapoo spayed. Recently has become incontinent but it is intermittent with no pattern. All tests are negative, no infection, PH 5, feed on Eden. Any ideas? Vet suggests changing food to Royal Canin and an ultrasound to check for crystals. Just wondering if anyone has any ideas, as don’t really want to feed low grade food, when she has been successfully fed on Eden with no problems.
