I am the proud owner of a Mastiff Cross. (Old English Mastiff/Rotty. He is
perfect in every way but one. A re occuring problem is that his movements
are not right. He tends to "go" in threes, the first is firm, the second is not
so firm and the third is literally water. This problem keeps returning for no
apparent reason. Is there a new food source I can try. Currently the only food
which agrees with him is Chappie Complete, with Pedegree Chum Meat. He
has always had a delicate tummy when it comes to food, not that his mouth
realises this!! Any advice would be most appreciated as obviously I am concerned
about his weight gain, He is 19 months old and approx 9 3/4 stones.

Kind Regards
Caroline

Have you had the vet check him out for Colitis? It sounds as if that might be his problem. Yoghurt helps a bit.. I'm not sure what else will. But there are others on here who excell in tummy problems :) :) :)
