Both my dogs became incontinent of urine on this food
I used Markus muhle food for ages for 2 dogs, but last year both dogs became incontinent of urine and started drinking a lot of water. I didn't realise it was both of them at first, assuming it was one of them, then the other. I spent over £900 at the vets on blood and urine tests for them both. There were no conclusive results from these tests. I suspected it could be the food and changed brand. I have not had an incident of incontinence from either of them since.
