We've finally relized that our GSD dog has food allergies!!!.... so according with our Vet we started an exclusion diet.
We started to giving him boiled rice+plain yogurt+flexseeds oil for 5 days, than recently we add about 200g. of kangaroo mince... he's doing fine!!
The only thing that we couldnt work it out was the amount of the cooked rice per day!
do anyone able to halp us??
