I test the dog food with my 8 year old Labrador as part of product testing with "insider". Labbis eat you know, everything, so of course, not a problem as far as the seizure. The food smells very good, especially the fish smell, the packaging is resealable, plus. The size of the kibble I personally find perfect, as they are very flat and small, almond-shaped instead of round. My dog swallows his food always down without chewing, for they therefore certainly beneficial if you are not a huge lump in my stomach. The price I find inappropriate, and I actually have to complain about "brand feed" each time, but you are doing everything you know, for man's best friend.
What I find not so good is the high protein content of the diet! With approximately 30% too high. Furthermore, the fat content of around 20% is not too bad either. For a dog with heart problems (such as ours) is not recommended! I pay much on the ingredients and will probably stay with my "old" feed with 17% protein and 14% fat!
