Hi I have got two GD's my 9th and 10th.
To me they are the best dogs in the world, apart from the droole,the passing of wind and the zoomies ( a mad 10 or 15 minutes every morning and night , where nothing or no one is safe ).
As for the gastric problem, you can buy a stand to raise the feeding bowl or as I do get a strong sturdy cardboard box and cut a hole in it so that the bowl sits in it.Then when it gets to dirty or soggy chuck it away.
The choice is yours but I wouldn't be without my two.
