Hi, Try the Forthglade salmon and potato, no grains , no rice.Had endless problems with Rosie and taking Her off all grains was suggested by the vet, definately made a difference.She is also on ( or was now on local shops own make) Barking Heads kibble salmon and potato.A friend who is a dog trainer has a pup who wont poo out on walks at all, Her other dog wont use the garden , She has tried all sorts of things to get them to do both with no success lol.Good luck
