Dog food made my dog extremely sick!!!

Purchased Dr Hahnz Dog Food from Checkers Hyper<br> The day after giving my dog her 1st bowl from the 8kg bag, signature range for adults she was unable to move, throwing up all over, constantly crying.<br> <br> At 1st I didn't think anything of the dog food and thought she had just gotten sick in general.<br> <br> She stopped eating during that stage. I purchased tin wet food that she likes, she ate that until she got better.(4days of being immobile and vomiting)<br> <br> She was feeling better and got back to her old self, tail wagging and running around like normal.<br> Once again filled up her bowl with Dr Hahnz. The next day immobile, loud breathing, vomiting and diarrhea.<br> At this point I started to think the food could be the cause. exactly the same as the 1st time she stopped eating, I again purchased wet dog food so she would eat. took her again 4 days to get better after being unable to move and yelping when someone touched her her stomach.<br> <br> She was back to her old self this week, last night Friday 19th I gave her a hand full of the dog food in her bowl. Low and behold this morning she can't move, heavy breathing and tail between her legs!!!!!<br> No answer from Dr Hahnz contact centre, will try again Monday
